M2 V7 pal DISK READ ERROR...

**Endr_PS2** · 10-12-2003,12:20 PM

After 2 days that my client was very pleased from the modchip I fited for him he returned the machine to me.
M2 pro V1.3 on a new V7 pal machine work fine for 2 days, suddenly stop reading any disk that work on other machines.
The browser is come up, after pressing X the screen change to NO DATA and down blinking READING DISK... for long time

The CD/DVD drive was replaced to ensure that is not a laser issue
All the fuses are OK.
The M2 took out completely with all the wires, all the soldering point cleaned and the bios checked with a big magnifier for bridging.

How do I continue follow up this problem?

My client says that the problem causes from the chip installation and demand a new machine from me.
In my record about 300 machines that I fitted, I never stand with a problem like this.

What do you think guys, is it the fitter problem? (The machine work fine for 2 days), did anyone know or hear about M2 that affected the machine after it was tested and run fine?
Or the client is right with his demand?
Is any one stand against a similar situation?

I'm quite sure that the modchip can't screw the PS2. It takes 3.45v in to power itself and the other wires, if not in any way shorted directly with power, read and write data to the apporpriate PS2 cache. SCEx is the exception, which is a pulse, as are A, R and W which enable/disable BIOS or CD/DVD activity on behalf of the Messiah 2.

There are many possible causes including:

1 Something in the disk cables - come adrift, not locked down, damaged

2 Some solder bridge or tracking at a voltage point and something else

3 Bridging on the CD/DVD controller

4 The chip moved and shorted a part directly without blowing a fuse or the client dropped the PS2

You are between a rock and a hard place I'm afraid. Your customer will say the only thing that's changed is the addition of a modchip, you won't know whether or not the client dropped the PS2 or somethig.

If there is no evidence of physical damage to the PS2, I'd say you need to take a view of your future intentions in the business as a matter of goodwill.

Not the best of situations to be in and I hope that others may shed more light on the symptoms.

Yes charlie there is more then somthing in this opinion of goodwill
as you act with me lately and I thank you for that.

I also had the same problem with both V9 machine with 1.31 messiah2, the ps2 worked 3days and the other 2weeks and then the disc error happened...

I'm not blaming the M2 but it never happened before with any other ps2 I modded (with 1.30 M2)
the problem is that one or both of the BA chips are blown even if the fuse under them are ok...

It's a very strange problem but it's a fact that it's happens sometimes (mostly with M2 1.22 and V7)

Try to change one or all of the BA chips and see if it works

By the way where could you find BA spare parts for the new V9 PS2 ?

Thanks

**Endr_PS2** · 10-12-2003,05:05 PM

Is there a way to check the ba chips with ohmeter to verify they are faulty?

**uns97** · 10-12-2003,06:55 PM

BA's can be partially damaged, and so that it's hard to check them for sure. The symphtom you described seems to be a partially blown BA chip, we repaired a lot boards with this problem. Anyway, I wrote about this that strange things may happen after modding a machine, even it is done with the biggest carefulness. And strange but mostly with V7 machines. (and BA) And to avoid this, phew, there's not that much I can advise, this is something that some of us have to live with, I also burnt a few BA's when modding, and no matter what chip I used, I had a few that killed BA's at the first powering on, or some days later...

Terminator-0: Don't blame this whole thing on Charlie, or Messiah2. As I said, I have seen several chips that cause this, Magic3, NH3, even Matrix can do this. (and I am sure even DMS3 too) I am not that happy that things like that happen, but can live with it, to be honest, it's even easier to get the BA replaced than replacing the whole MB. Anyway, yes it would be great to know how this can happen, but I am almost sure we will never know it for sure.

regards, Stephen

**uns97** · 10-13-2003,07:25 AM

Terminator-0: I see your point and accept that. I also installed some Messiah 1 and all work fine. Yes maybe the big rush in the competition changed everybody to turn from quality to quantity. Anyway, yes I also heard and saw Charlie's suggestions. And many others aswell. Some people always think every fault is because of a bad install, or a lame installer. To be honest, I don't think that Charlie is among them, as his tutorials and thoughts helped (many people) many times. As he was telling not that much bad thing about messiah2, phew, I don't care. As said, I saw other chips to fail too. (so why do we blame it only on Messiah2 ?) We have to accept that modding isn't always just fun and grabbing up money. It's sometimes a hard work, when something went wrong. I hadn't been the happiest man on the Earth when a NH3 killed two boards in 2 hours sometime back in April. I opened a topic about it. Got answers like I was too lame to install and it was surely my fault, and so on. I could admit that, after modding about 100-150 machines without having any trouble. I could learn that I have had a bad branch of chips which kills PS2. And none ever mentioned that with a "simple" desoldering of the BA and replacing it will solve my problem. I have been reading this forum for almost one year, and well got a lot of serious answers, and met helpful people. As always there are a few people that just crap and blame everything on the installer(s). (and now I don't think that it's Charlie, anyway) Well, it is totally offtopic but just wanted to say.

regards, Stephen

I need 2 new BA chips to try solving the problem.
Can you recommend me a reliable and good price that sale those chips?
Is their replacement for those chips?

I never replaced the BA on PS2 mobo but I disassembled an old CD drive for PC and found similar chips to practice. I bring closer to the chip a professional hair drier and wait until I can take it out.
Is this method good? Can I cause damage?

**danzig455** · 10-20-2003,04:04 PM

I thimk nearly ALL of us mke mistakes that cannot be easily figured out. I've learned that you ALWAYS have an extra stash of motherboards for all versions.

Who knows? maybe it is your fault, maybe not but replace the board and either try and figure out the problem on the faulty one (everything is fixable, it's just diagnosing that's the problem.)
This can be a stressfull buisiness. Nobody wants their machine to go belly up, especially after a cool new addon like a mod.

There are severel times that i've dealt with angry customers who are unbelivebly stupid, to the point where it's mind blowing, but be glad that your there and the're not. Replace the board/whatever and save it for a time when your bored and fix it then.

It's not worth it to artgue with customers, regardless of their stupidity. You should be making a FORTUNE on these installations
I know people who made $100,000 in six months. I haven't made that much but we should all be doing very well, well enough to replace a board or even an entire machine and not blink twice.

There's nothing worse or more cheap than a well off person who refuses to budge when it comes to buisiness. So we make $800 today instead of $1000. Let it slide
