PS2 Drive Don't spin

**supermathieu** · 03-24-2006,10:25 AM

I attempted to install a matrix infinity green dot in my US ps2 v.10 when I boot the ps2 for the first time everything went fine, but after a few sec. the cd stop spinning and bring me back to the os, now when I put media in the cd drive nothing happen. I can navigate on menu, I can open and close the cd tray but the ps2 don't see cd in the drive. All ribbon are well connected, Is the motherboard I have to change or the ps2 cd drive?

Bad BA chip?

**supermathieu** · 03-24-2006,11:32 AM

well, what is the ba chip? is it in the dvd drive unit?

this problem is common on v9-v10 and also some v12 consoles... its the BA chip that might have burnt out... you can replace the BA chip on your console, a replacement will cost you about $14-$15.... and this should fix your prob.. but it could even be the LA chip that might have burnt out but LA usually does'nt have probs.. try replacing the BA chip, thats all i can say.. if you cant buy it then take it out of a dead ps2, if you have one... the name of the chip is "BA5815FM" and its printed on the chip...
Now to talk about the location.. the BA/LA chip resides on teh ps2 main board.. search over it and you'll find it(written on the chip)... now you say u have a v10, right? Then you should have done some research on it cause this is a known issue with v9/v10's... now if after replacing the BA chip the problem still persists then you'll have to change the LA chip also otherwise if your ps2 behaves normal then do the following to prevent it from happening in future..
1) Carefully lift Pin17 of the LA6508 Chip,
2) Ensure no solder links it to the pad it was just lifted from,
3) Link Pin17 to 5 volts

Well, thank you very much!

hey just a thought but might work... replace the LA chip first and then do wat i told you... maybe u wont have to replace the BA chip...

Ehmm Xmod your not quit right
Ba5815fm is not in the v9/v10/v11 range but only in the v4,5,7,8
The La6508 is in the v9/v10/v11 and thats the one what is making the problem

Man ... I think his PS2 got bitten by the "gold disc" syndrome.
It's when some resistors on the mobo get shorted. Since they carry the address lines from the I/O Processor (IOP) to the DVD drive DSP chip (It's also the interface to the DVD drive, how the PS2 access it and gets the data out) it can cause the "gold disc" problem by causing address information to be mangled, thus causing the IOP to read/write to wrong registers on the DSP chip. Sometimes this is serious enough to cause BSOD. It's easy to fix but requires a scrap mobo to take out the resistor pack.

small thing that came up in to my mind and that is ps13
if that fuse is blown you can have the same symptome

its not very common but it is possible !
