PSX won't read discs
Posted: March 3rd, 2019, 3:44 am
Hello, I have had a problem for the last 3 months with my SCPH-9002. It spins for a while but then it goes straight to the menu. I can see a red dot when I press the door tray sensor. I tried these things so far to no avail:
1. Swapping laser with a new one (both are KSM-AEM)
2. Tweaking pot on both lasers (though lowering resistance made the red dot stronger and disc spinned faster)
3. Turning it upside down (it's noisier, but something pops in there after it stop turning, it could be laser hitting the disc)
4. Changing IC702, except I swapped it with an incompatible one so the old motherboard is dead as I can't find a new part (AN8732SB)
5. Changing the whole motherboard (PU23, I ordered it from FullyRetro, no modchip was installed on the board)
No matter what I try, it won't work. One thing I noticed is that the disc is kinda wobbly when it spins, but it's on both lasers. Any help is absolutely welcome.
