ps1 modchip identification and repair
Hi, I have a modded playstation that was working well, but yesterday during a play session the console suddenly stopped reading the disc, the disc was still spinning but the reading head/laser was making noise, and now the console is unable to run any CD, original or CD-R copy. The console model is SCPH-7502 PAL.
First I would like some help to identify the modchip (12C508A) on it (I don't know the history of that console) as the chip has only 3 wires used + one bridge on the motherboard. Then I would like some suggestions of what could be wrong with that console because, as described, it was perfectly working but suddenly is unable to read any game.
I found an old modchip that I bought a very long time ago, but I no longer have any information allowing me to identify it, do all the chips of this model (12C508A as well) connect in the same way or is it specific to the firmware it contains ? It was provided with 6 wires to solder it.
Thanks.
