I'd like to expose a problem to the community. Please give me advice.
Yesterday a guy brought me back a V/ (gh-019) I modded 2-3 months ago with a Magic3.1, saying that suddendly it doesn't take any media. I take it and verified that it turns on correctly, the leds are ok and the eject works correctly. The problem is that any media you put on (cd or dvd, original or backup), the drive start spinning with a loud noise and the ps2 stays in the electrons screen without boot (no RSOD or other things).
I opened up and removed the Magic chip, checked all the solder points for bridges etc (especially cd/dvd points) burt found nothing. The ps2 continued working in this bad way. I looked at the drive while inserting a media and saw the it was spinning and the sled with the laser was moving slowly (probably trying to find a correct groove). At this point I took a gh-022 mobo from MY ps2 and mounted it on the 'bad' ps2 and IT WORKS CORRECTLY! So I assume that the drive and lens are all right. The problem is on the mobo. Next move was to check the BA chips and fuses. All the fuses are good, PS11 and PS12 are all right, and pin 8 of BA5815FM chip doesnt' give zero. Well, I'm a little concerned now...
Anyone has an idea ?????
Tnx for all. Byez !!!
