(multiple sections are contained on each page; scroll down if you don?t see
the data you want)
You might wonder why your PS2 isn't working. Well, if you're getting Disc Read Errors on multiple discs, all of which appear to be in good condition, then you most likely have one of two common problems. Either your laser is being obstructed by dirt and dust, or the laser's voltage is not properly adjusted.
Note that this FAQ was written for people with little or no knowledge of electronics. The technical-speak has been highly simplified for those without the electronic know-how.
If you are WELL versed in electronics and own an oscilloscope, and a 10:1 test probe with ground clamp, see MrB / DNA's very detailed FAQ. it includes directions for adjusting laser voltage, and replacing the laser unit. You will need software to unzip the file, and Adobe Acrobat Reader to view the PDF file. Another file that will aid you in using an O-Scope to adjust your voltage is located here.
The Playstation 2 is a precise gaming console. Fixing the console yourself should not be done unless completely necessary. You may also risk electric shock, so do anything within your power to remain safe while attempting these repairs. If you can, use an anti-static wrist band to ground yourself. This device is available at any electronics store (e.g. Radio Shack.)
These repairs require opening the case, which WILL void your warranty. If your console is still under warranty think twice about cracking the seal.
Adjusting the laser's voltage requires some precision, being too rough can cause damage which you will not be able to fix. Be very careful when doing this process!!! Be prepared to pay Sony over $120 to fix this part if you damage it!!!
Always attempt the laser CLEANING before trying to adjust the voltage!!!!!!
This is the easiest thing you can do to attempt to fix your PS2, while it hardly ever works it only take a minute or two, and should be done first before you take apart your machine.
1) You must be in the "main menu" screen of the PS2 console, the first screen that comes up when you start with no disc in.
2) press the "triangle button"
3) Select "Console" from the top using the up directional buttons and press
the "Triangle" button
4) Select "On" using the up and down directional buttons and press the "X"
5) Insert a disc. The console automatically starts the diagnosis.
CLEANING THE LASER:
-Normal phillips head screwdriver
-Jewelry (Small) phillips head screwdriver
-Rubbing Alcohol (Isopropyl)
-Can of Air
Taking the PS2 apart is fairly simple, nothing too complicating. All that you're basically going to do is remove the upper shell, remove the lens cover, clean the lens, and put everything back together again. Just be sure to follow the steps, and read through each step and understand it before going through with it. Sometimes the instructions may seem a little too in depth or complicating, but just use your common sense and you should understand what I'm trying to say. It's a lot easier if you print it out, as well.
1. Make sure that you have a neat, clean area set aside for taking the PS2 apart. A small box or cup to put screws in wouldn't hurt, either. Flip your PS2 over so that the bottom (horizontally speaking) is facing up. There should be 6 screw covers, 4 plastic and 2 rubber, which need to be removed. You can use the butter knife for this, or your nails, whichever is easier. Screws should be uncovered under them. There should be 2-4 more screw covers on the outer side of the base, underneath the controller ports (where the system goes out a few inches from the base). The older model PS2's have 4 screw covers, while the newer ones have only 2. Remove them all, and you should now have a total of 8-10 screws unveiled. Set the screw covers aside.
2. Using the normal sized phillips head screwdriver, remove all of the screws. REMEMBER where the longer screws go, or mark the holes with a piece of tape or anything that will remind you of which holes the long screws go into. If you do not remember where the long screws go, you could put a hole through a circuit board by trying to force the long screw in where it is not supposed to be. Make sure all of the screws are removed, and put them aside.
3. The PS2 shell should now be ready to remove. ONLY the UPPER side (with the PS2 logo) needs to be removed to clean the lens - Leave the BOTTOM side on. But, be very careful when taking the upper shell off, or you could damage the PS2. To take the shell off, you first should place the PS2 horizontally, with the PS2 logo facing up. Next, you need to move the side of the shell out a little, sideways, so that the Eject/Reset buttons are not blocking the shell, and it can be lifted off. Just play around with it a little and you should get it. Then, lift it at an angle, like opening the cover of a book. Take the bottom (Vertically speaking) of the shell, with the PS2 logo on it, and lift it an angle. You should notice a small wire around the area where the Reset/Eject buttons are. The wire should be taped to the top of the Lens cover. Remove the tape, and then carefully lift the cover so that it is laying flat, and the PS2 is open like a book, connected at the middle by the wire. The Lens is now almost accessible.
4. To gain access to the lens, you need to remove the lens cover. The lens cover is located right in the area where the PS2 ejects the tray out, just above the tray. Its square shaped, and has a small white circle piece on it. To remove the lens cover, simply take out the 2-4 screws located on the side with the Jewelry screw driver. Place the screws aside, and lift the lens cover. You should now see the lens, a small circular glass piece located in the back of the disc tray.
Now comes the optional part. If you have a Can of compressed Air, you can use that to get all of the dust out of the PS2. Spray all around the area, especially the fan. You don't need to remove anything, just spray. When it seems that the dust is removed, go on to step 5.
5. Now, the lens can finally be cleaned. Take the Q-Tip and swab it generously in the rubbing alcohol, but make sure that there's not too much on it so that it's dripping. Take the Q-Tip and carefully yet firmly rub the lens in a circular motion for a good 30 seconds. Then, flip the Q-Tip over to the dry side and dry it off in the same circular motions. The lens should now be clean.
6. All that's left now is putting the PS2 back together, which should be fairly easy. Place the lens cover back on, making sure that it's tight and snug in position. Screw it in place. Then, tape the wire back onto the lens cover and flip the shell back into place on the PS2. Screw the screws back in, making sure the longer screws are going into the correct holes. The screws don't all have to be tight, so don't sweat it if 1 or 2 of them aren't seeming to fit into the holes all of the way, as long as they're in the right holes. Put the screw covers back into place, and you're done. Congratulations, your PS2 is now cleaned, and working like new, without having to spend a dime! Feel free to repeat this process in the future, as well, if Disc Read Errors ever occur again.
DO I NEED TO ADJUST THE VOLTAGE?
To determine whether or not these repairs are necessary, read the following carefully...
You may need to adjust the voltage if:
1. Your PS2 reads games on DVDs but will not read games on CDs
2. Your PS2 reads games on CDs but will not read games on DVDs
3. Your PS2 will read no games; you have already cleaned the laser and you are using undamaged discs
Do not adjust the voltage if:
1. You do not receive the message "Disc Read Error" in the browser screen when trying to load problem discs
2. You have a Playstation 2 Version 4 or higher: a PS2 with 8 screw covers on the bottom rather than 10. (directions for fixing these models will be available sooner or later)
3. Your PS2 only gets errors on certain CD or DVD games, not All CD or DVD games. Try cleaning the problem disc, or using a Disc-Doctor
4. You receive "error reading CD" during games such as GTA3/VC or other games that stream data (clean the laser in this case)
Please note that fine tuning may be needed if your PS2 reads CD games but not audio/PS1 CDs (or vice versa)... Or if you?re PS2 reads DVD games but not DVD movies (or vice versa)... Personally I don't suggest fine tuning without a voltage meter.
CLICKING AND SQUEAKING EXPLAINED
Clicking is most likely the laser unit moving back and forth trying to access a piece of data. If it can't find that data it will move back and forth until it does. In the case of a DRE, since the PS2 never finds that data it will continue clicking until you receive the error.
In case clicking is loud, or you hear squeaking, it might be a good idea to clean the slide rods that the laser rides on, and then add some oil or grease. I will be adding more information on this very soon.
Loud clicking can be the result of warped discs in the drive, check to see if your disc is warped if you get loud clicking.
ADJUSTING THE VOLTAGE:
Read this instruction all the way through, and make sure you understand all the steps before doing anything!
1. Remove your warranty sticker, located next to the power cord. Take off the cover to the expansion bay.
2. Remove the screw covers on the very bottom of your Playstation 2. There are six total. Four of them will be rubberized and two will be plastic. You may need a flat head screwdriver to remove the plastic ones. Ignore the extra 4 plastic covers on the raised, upper portion of the underside of your PS2, these are for removing the top shell.
3. With a phillips-head screwdriver remove the six screws under the covers you just took off. Four short and two long.
4. Pull up on the bottom portion of the case to remove it.
5. Remove the metal shield covering the circuit board (the shiny one). With the front of the PS2 facing toward you, it is on the right. There is only one screw holding it in place, it has an arrow pointing toward it.
6. Remove the expansion bay plate (the dull one with holes). With the front of the PS2 facing toward you, it will be on your left. Once again there is only one screw holding it in place with an arrow pointing toward it.
7. Lift out the expansion bay housing. It is attached to the circuit board by a short ribbon cable. Under this are the laser control screws.
8. The laser control screws are on a small amber circuit board slightly recessed in the plastic case. You will be adjusting one or both of the two small silver screws with a black screw in-between them.
With the front of the PS2 facing you, the silver screw on the LEFT controls the voltage for the CD reading. The silver screw on the RIGHT controls the voltage for the DVD reading.
I suggest putting a small dot, with a sharpie pen, in the 12 o'clock position of each screw to help with the adjusting process...
9. Stand the PS2 on its side (vertically, memory cards at bottom, power button at top) at a slight angle. You won?t be able to stand it at this angle unless it is done on carpet floor. Having a friend hold it in position might be better. Make sure that the expansion bay housing does not come in contact with the circuit board, as you will be turning it on, and you don?t want the
metal housing to short out the board. Let it hang down, away from the board.
10. With the PS2 plugged in (power and video) turn it on. You are ready to adjust the voltage for the laser. Only adjust the screw for the type of disc you are having problems with. If you are having problems with both, do them one at a time. Remember, now that the unit is on its side the CD voltage control screw is above the DVD control screw.
If at all possible use a non-metallic screwdriver, as static electricity can ruin this portion of your PS2 (a $65+ part!)...
11. Turning the screw clockwise increases the voltage, counter-clockwise decreases the voltage. Because you risk of blowing the laser if you give it too much voltage, always start by decreasing voltage. In my experience, you generally have to add voltage, but for safety, I suggest you reduce voltage first.
Using a small screw-driver (non-magnetic & non-metallic if possible) turn the appropriate screw counter-clockwise two degrees. Load in the CD and wait, if you still get a disc read error move the screw another two degrees. Repeat the process...
If you still get disc read errors after about 20 degrees of rotation, put the screw back to the 12 o'clock position and start moving the screw clockwise two degrees at a time.
It may take a while, but you will most likely find the sweet spot where your discs begin to read again. I have never had to move the screw more than 30 degrees, although I have heard as much as 180 degrees are needed for a modded PS2 to play backup CD-Rs.
12. Try a few different trouble discs before re-assembly to make sure you don?t need more fine adjustment. As well, hold the PS2 elevated in the horizontal position and make sure it reads while in this position. I have found that slightly more voltage (2-6 degrees) is needed to run discs in the horizontal position than the vertical position.
13. Turn off the PS2 and re-assemble it.
PROneTworks is not responsible in anyway for any damage you may do to your Playstation 2 while attempting the procedures within this document. Please note that this FAQ is not guaranteed to fix your PS2, you may actually end up doing more damage!
To get the free repair you need to call up Sony at 1-800-345-7669. Their
regular business hours are Monday-Saturday from 6AM to 8PM and on Sundays
from 7AM to 6:30PM Pacific Standard Time. You need to call during those
hours. When you call up you will get an automated menu, when the options
start playing just press 0 to be connected to a Consumer Services
Representative. One thing to remember from this point on is to NEVER say that
you found out about a free repair on the internet. There's no dishonesty in
this, but the reason you shouldn't tell them is because they may then think
that the only reason you're calling is not because you have a real problem,
but because you want a free tune-up. Be wise with your words. Another thing
to remember is to not volunteer information. Only answer what they ask,
nothing more, nothing less. When they ask you why you are calling make sure
you specifically mention that you're getting Disc Read Errors. Those are the
magic words; you won't get very far without saying "Disc Read Error." After
this they will ask you several questions before offering the free repair in
order to see if you qualify for it. The answers they're looking for are
quite obvious. However, I don't think I would be allowed to list either the
questions or the answers here since that would clearly be dishonest and
probably against GameFAQs policy. But they are very easy and really
no-brainers. They will ask if you've tried using the Diagnosis Mode. If you
haven't they will walk you through it step-by-step. The Diagnosis Mode rarely
has any effect, but Sony wants you to do it before giving out a repair, so
just go along with it. Once you've gone through the song and dance they
should offer you a "waived fee" repair. Listen to and follow the instructions
they give you very carefully. They'll ask you if you want to write down the
information or have them email it to you. I suggest having them email it to
you since it'll have the number that gets you the free repair already written
at the top and it has all the blank spaces for you to fill in the necessary
information so you won't forget to put down anything. Once all of the above
is completed, you can move on to the next step. Shipment.

10. Final Notes
1. REVISION HISTORY
Version 0.5 - First version. FAQ is nearly complete.
Ah, the dreaded PlayStation 2 Disc Read Error. Taking one step into the
GameFAQs.com "PlayStation2 General" message board sends plenty of "I have a
Disc Read Error, please help!!!" messages flying onto your screen. Hopefully,
this FAQ will change all of that.
If you clicked on this FAQ, you are likely suffering from Disc Read Errors (or
"DREs", as the PlayStation2 General board lovingly refers to them as). But for
those not in the know, a Disc Read Error is when the PlayStation 2 refuses to
play a certain game. The game won't load, and the PS2's browser screen will
display the tragic message of "Disc Read Error."
This FAQ details every method that I know of to repair DREs. I RECOMMEND (but
not demand) that people using this FAQ should perform all of the repair methods
in the order that I've set them as in the Index section. Meaning, start with
the "Quick Fixes for Disc Read Errors", and if those don't help, move to the
"If your PS2 is filled with dust..." section, etc.
Before we begin, I'd like to say that I take no responsibility if you destroy
your console using any method depicted in this FAQ.
3. WHY AREN'T MY GAMES WORKING?
Your PS2 is having trouble reading discs for one of two reasons. Either the
lens is filled with dust, or the amount of voltage going to the laser isn't
balanced. However, repairing these problems can often cost either money or
time, sometimes both. That's why I recommend you starting with the "Quick
Fixes for Disc Read Errors" section before anything else. These usually will
not fix your machine to the perfect working order that it was when you
purchased it, but the Quick Fixes take almost no time and no money.
You may also be wondering why your CD games work, but not your DVD games, or
vice-versa. If not all of your collection of games is giving you trouble, then
you most likely have a voltage problem, although the other methods I describe
in this FAQ can also help. Why do some games work while others don't? Because
the PS2 has to spin CDs much faster than DVDs, both disc formats require a
different amount of precision control from the laser. If you don't know if
your game is a CD or DVD, look on the disc's packaging for either a "DVD-ROM"
label (for DVDs) or a "Compact DISC" label (for CDs.)
(Just a note, all PSOne games are CD-based)
4. QUICK FIXES FOR DISC READ ERRORS
Quick, cheap, and easy, these methods are useful for the "gamers on a budget"
that cannot afford to buy tools or perform big operations of their consoles.
4.1 - CLEANING YOUR DISCS
Cost efficiency - 4.5/5
Convenience - 5/5
Effectiveness - 4/5
Tools you will need:
1. The problem disc.
2. Lint-free cloth.
3. Rubbing alcohol (optional).
Ever since CDs replaced casettes as the main audio format, discs have gotten
dirty. And dusty. And grimey. And this oftentimes can lead to problems
reading said discs.
I've developed an effective way to clean discs. Take any lint-free cloth (such
as CD wipes that are sold in record stores) and use it to cover the lid of an
opened bottle of rubbing alcohol. Turn the bottle upside-down so that the
alcohol spills into the cloth. Now, crumple the cloth in your hands, so that
the alcohol spreads across the cloth without making it soaking wet. Use this
moist cloth to wipe your disc. You should move the cloth from the inside of
the disc (where the CD hole is) to the outside when you wipe. Circular motions
are very dangerous and can scratch your disc.
4.2 - DIAGNOSIS MODE
Cost efficiency - 5/5
Convenience - 3/5
Effectiveness - 2/5
Tools you will need:
When you e-mail Sony about your Disc Read Error problems, they are guaranteed
to say two things when they respond to you. The first is that "Disc Read
Errors on our console aren't common, the PS2 is omnipotent and you are not."
The second is that Diagnosis mode could be the solution.
Load your PS2 without a disc inside and wait until you get to the main menu.
Press Triangle and highlight "Console", then press Triangle again and set
"Diagnosis" to ON. What does this setting do? Basically, it focuses the laser
on the disc so that it has an easier time reading discs. This trick has never
worked for me personally, and I rarely ever hear of it being a success. In
addition, you must turn this setting on EVERY time you load your PS2, as the
PS2's system settings are never saved when you turn off your console. Boo.
4.3 - ROTATING THE SYSTEM
Cost efficiency - 5/5
Convenience - 5/5
Effectiveness - 3/5
Tools you will need:
Remember how the original PlayStation had a much better time playing CG videos
and music properly when it was turned onto it's side? This method is a lot
like that. Basically, the PS2 seems to have an easier time reading discs when
it's in the vertical position than in the horizontal position. Yep, it's that
simple. Don't worry if you don't have the PS2 vertical stand - you really
don't need it.
This trick has never worked for me personally, but has been reported as a big
help on the GameFAQs PlayStation2 General board.
4.4 - SCOTCH TAPE METHOD
Cost efficiency - 5/5
Convenience - 5/5
Effectiveness - 2/5
Tools you will need:
1. The problematic disc.
2. Scotch tape.
This was the trick that personally fixed all of my problem discs.
I first heard of this trick in the September 2002 issue of GamePro. In every
issue of GamePro, they have a one-page section called "Buyers Beware", which is
a Q&A section where readers write in if they're having a problem with their
games. As you might expect, a common problem in previous issues of GamePro has
been the PS2's Disc Read Error. But in this issue, a reader named "Jim M."
wrote the following letter to Buyer's Beware.
Jim's tactic involved placing scotch tape on the face of the actual discs. By
taking two 1-inch long pieces of scotch tape and putting them on opposite sides
of the CD (as close to the CD hole as possible), the PS2 suddenly has an easier
time reading discs. How is this possible, you ask? The disc is using the two
symmetric pieces of tape to balance itself on the laser, making the disc easier
to be read by the laser. According to Jim, an offset of balance on the disc
can occur when dust builds on the magnetic rubber device that holds the disc in
place. The tape fixes this.
However, this trick didn't work for me...right away. After pondering for
awhile, I took Jim's tactic one step further, and added TWO MORE strips of tape
onto the two sides of the disc that previously had no tape on them. Lo and
behold, it works! These two new strips of tape should still be 1-inch long and
should still be as close to the CD hole as possible.
I understand that these instructions may be confusing, without a diagram, so I
made a little picture that will hopefully explain it better, which can be
viewed at http://www.geocities.com/sonicquestc...tapemethod.bmp.
While this trick definitely worked for me, it doesn't work for everyone.
Namely, I've heard that this trick only works for CD-based media, and not
5. IF YOUR PS2 IS FILLED WITH DUST...
If you're reading this section, then obviously, the "Quick Fixes for Disc Read
Errors" didn't help you. If this is the case, then your PlayStation2's laser
lens is likely clogged with dust. Here are the known methods for fixing this.
5.1 - USING A LENS CLEANING CD
Cost efficiency - 3.5/5
Convenience - 5/5
Effectiveness - 3/5
Tools you will need:
1. A lens cleaning CD
Available at several electronics stores are "Lens cleaning CDs." These discs
are made for all disc-based electronic equipment. On the bottom side of these
discs (the side that is usually read by laser lenses) is a small cleaning
brush. As the disc spins, the cleaning brush wipes the laser lens clean,
freeing it of any dirt or dust that may have accumulated on it. If your PS2 is
suffering from a Disc Read Error because of excess dust, this will almost
definitely fix it.
Sony claims that these things can scratch the PS2's laser, but this is simply
not true. The cleaning brush is made of very light string, just like the
string you could find on a kite.
5.2 - VACCUMING THE MACHINE
Cost efficiency - 3/5
Convenience - 2/5
Effectiveness - 4.5/5
Tools you will need:
1. A vaccum cleaner.
2. Tube extension for vaccum cleaner.
Using the tube extension on your vaccum cleaner (which most every household
has), take the vaccum to the PS2 and let that bad boy go! The front vents,
ejected disc tray, and back fan should all be targeted. This will definitely
suck a lot of dust out of the inner workings of the machine, as the PS2 is not
an airtight piece of machinery.
5.3 - MANUALLY CLEANING THE LASER
6. IF YOUR LASER LENS NEEDS TO BE REALIGNED...
If dust isn't the problem, then an inproper amount of voltage going to your
PS2's laser is. You must fix this by finding two silver screws nestled deep
within the PS2's inner workings. One of these screws alters the amount of CD
voltage, and the other alters the amount of DVD voltage. If your PS2 only has
problems with CD-based games, you'll only want to tamper with the CD screw, and
vice-versa if your DVD games don't work. If your PS2 won't play anything,
you'll have to tamper with both!
However, this method for repairing the problem depends on which model number
your PS2 has. To find out what model number your PS2 is, read the General
Questions section. If your model number has "SCPH-30001" *ANYWHERE* in it, go
to section 6.2. If not, read on...
6.1 - Adjusting the voltage
6.2 - Adjusting the voltage for PS2 model SCPH-30001 (Version 4)
Cost efficiency - 4/5
Convenience - 1/5
Effectiveness - 5/5
Tools you will need:
1. Phillips screwdriver
2. Very small Phillips screwdriver (same as above)
3. Exacto knife
First, unplug all of the PS2's cables, and take the back expansion bay cover
off of your PS2 and flip your console upside-down. Take all of the screw
covers off of the bottom of your machine. If you're having trouble getting
some of the screw covers off, use a flathead screwdriver to pry them off. Now,
take the screws out. Not all of the screws are the same sizes as each other,
so try to remember where they originally went. Now, you'll notice that you
cannot take the system apart because of a large sticker on the backside of the
machine. DO NOT TAKE THIS STICKER OFF! If you do, it will leave "Void" marks
all over your machine where the sticker once was. Use your exacto knife to cut
the grooves in this sticker so that the system can come apart. Now, remove the
bottom part of the PS2 (the smaller part) from the top part. Be very careful
when doing this, as there's a ribbon wire connecting the two pieces together
that will ruin the machine if it is ripped or torn. Now, there are two screws
that hold a metal cover and the expansion bay down. Remove the screws and the
metal cover and expansion bay. The expansion bay cannot be removed entirely
because of another ribbon wire. Now, here's the hard part. While you are
still holding the expansion bay, you have to adjust the two silver screws.
They are recessed inside a cover but you can see them and get to them with the
screwdriver. One of them and adjusts the CD voltage and one of them adjusts
the DVD voltage. How do you tell them apart? If the front of the PS2 is
facing you, the left screw is the CD screw. Turn the screw you want about two
degrees clockwise, then plug everything back in, load the problem disc and turn
the PS2's power on. If the game still doesn't work, power everything down,
unplug everything, and turn the screw and additional two degrees to the right
and try the problem disc again. Keep repeating this method until you find the
right spot. When your games work, put everything back together and enjoy!
Have fun with your PS2s.
I think Sony stop offering this. It's $80 if you want to fix it now.
