Failed Laser Deck Installation - Grinding Noise And Drive Will Not Feed discs
Failed Laser Deck Installation - Grinding Noise And Drive Will Not Feed discs –
I have attempted to replace the KEM-400 laser deck in my ps3 today after it stopped reading discs a few days ago. Now when the console is switched on, a grinding noise is heard and the blue led on the front of the console flashes a few times and then stops. The console appears to function otherwise normally.
The drive will not feed in any discs and I have not attempted to force any into the drive.
Please could somebody advise if they know what I have done wrong and how I could go about repairing it?
I have tried checking the cog alignment as shown in this video: [ame="http://www.youtube.com/watch?v=CEN1kk31-zs"]YouTube - PS3 loader alignment[/ame] but it all seems to look present and correct as far as that is concerned.
One question I have though is are those two grey arms on top of the white ones at the front which move the mechanism supposed to be attached to the white ones and control their movement? As they don't seem to on mine and they both seem to move independently of one another.
Apologies if I'm not explaining this very well but if it helps then they are on the detachable part at the front which you need to remove to see the cogs underneath.
I have checked every other part of my drive and it all seems to be as he describes in that video.
Just to be clear, I mean these parts highlighted in blue below:
Any guidance which anybody could offer would be very much appreciated as although I've done PS2, Xbox, and Xbox360 repairs before, this is my first time I've had to work on a PS3 and it does seem to be a particularly fiddly drive to deal with.
The little grey parts circled in blue on your picture should move by themselfs, just make sure the little spring is in the right place causing the grey part to move back when no disc/movement.
The two arms above them should move together, and when moved the right one will flip a switch causing the motor to start, and the wheels will spin pulling the disc.
To get this drive working, it is best to work in sections with it apart until you figure out what piece is in the wrong spot, normally it is the big long left and right slider arms that raise the disc which is in the wrong spot.
A common problem in reassembly is to have the left arm too low, and touch the loading gear, this arm should be all the way to the back, without it touching the loading gear, and it is connected on the bottom with a arm to the right side. -- tapping the right side up, should cause the left side to go down and just touch the loading gear. -- if not, you might have gotten the connecting arm on the bottom loose or out of the plastic groove. -- i will see if I can find the pictures for that part of the drive which might be the problem.
Trust me, the ps3 drive is the most pain in the neck for loading drives, and even with mine tons of repair experience, the first time I came across the ps3 drive is was real headache maker, since I didn't have another working drive to compare to, and my first drive was already messed up.
Even now, with doing over 15 to 20 laser replacements per week, once or twice I will run into this problem, and due to time frame just put the drive aside, take the good replacement laser out and stick in another drive on the shelf, and work on the grinding one later, as sometimes I find it can be caused by a small little peg missing in the upper lid, and one of little cogs needs to get replaced.
Thanks Gary, I thought that may be the case to be honest, I did check the sliders and the one on the left doesn't seem to be engaged with the small black cog next to it at all and moving one slider upwards forces the other to move down so I'm assuming it is probably those bumpers that are causing the problem.
The Wikihelp article where that picture was taken from also mentioned the grey bumpers and to check they were correctly aligned with the springs, but I have taken then off and had another look at them and the only spring I can see is the small thin metal coil which is currently wrapped around the stand for the white bumper underneath and is running along the centre dent in the spindle on both the left and right white bumper. I suppose the main problem in question is like you said of not having a working drive to use as a template which is causing me the most headaches here.
I am glad that it isn't just me though, I have done work on PS2 lasers and the internals of 360 drives etc before and there has never been any hassle but I just can't believe how fussy these BD drives are. Admittedly, I always found the PS2 to be a particularly unpleasant console to deal with though so I suppose it may just be Sony games hardware in general.
After reading thru this thread again, and also the one you made in the ps3 section over at "xbox-scene".
I thinking also maybe you should double-check the sensor area, and the small wire running down the top of the lid to the bottom of the board, as this shorting out might be making the noise you here, since you saying the blue light flashs a few times, so the sensor thinks there is a disc going in when there is not.
See this other thread made by another user with the same problem for more info:

im running into similar problems. the main trouble for me is that my setup seems different than every one i have come across in pics and youtube vids.

after the swap and firing it up and trying to put a disc in, the long left arm engages and brings up this white tab that blocks me from putting anything in
everybody seems to say that the left arm should not be engaged into the gear, but when i put it all the way back and try to put the "boomerang" shaped piece back on, it has nowhere to grab onto the left arm
it only slots in when the left in gear
i tried the setup with the arm all the way back. thats the only way it allows a disc in, but it wont read or eject the disk....im assuming because as the right arm goes up, the boomerang piece has nothing to push the left arm into gear to get it eject
am i missing something?
you said you do a lot of replacements, so i thought maybe you worked on the model thats the same as mine
