PlayStation Development Network

I happened to have purchased this DTL-H1001 dark blue debug PS1 off Ebay. I love the thing to death, and it was manufactured in August of 1995 (And the doesn't use a power adapter like the other debug units) For the first week the thing started to work perfectly fine and played just about any game I had, but after that, whenever the console would display the Playstation logo, it'd be all corrupted and wouldn't load past the screen...Ironic given the fact that the CD and memory card menus work and the thing can play any CD fine. The corruptions would look different each time I tried to load a game, and I've tried adjusting the pot on my laser and have used other lasers to try to get the games running but still no cigar. I would also start to hear some audio corruptions, though not present every single time I start the console. I have come to notice that these corrupted screens look and sound exactly as of Fearful Harmony, which is in itself strange and creepy. I've been curious as to what has caused this, whether it would be the IC102 (Bios chip) or something else. Am looking for help as I would love to get this thing fixed!

Is there visible trace damage on the board? Does the machine work after it warmed up?
Is there a chip called CXD2922 on the board?

Those CXD2922 (SPU chips) appear to be prone to failure.

Open the console and whilst it's running, press on all the IC's one at a time whilst it boots up (except the power supply of course, don't touch that at all and stay clear of it!). Sounds like one of the chips isn't soldered well anymore, and I have a feeling it might be the RAM.

You could be right, I didn't press down on the console with the power running (Nor could I because I'd have to store the laser somewhere) but I did press on the IC309 and it feels a tiny tiny bit stiffer than the other chips? Not exactly sure but it could also be the CXD2922

It could be the CXD2922 on the PS1, but not exactly sure. I don't see any damage on the board, and the machine works
