Chip stopped working?

I installed an H20 in my friend's v14 PSTwo a couple weeks ago. It was working fine, booting backups. Occasionally, it would show a red screen display on backups, but a quick reboot would boot the disc. Well, sure, that was kind of annoying, but it was something my friend was willing to live with. But, all of a sudden, the chip stopped working. Now, it won't boot any backups ever. It's showing red screens on all backups. The PSTwo was fine one day, my friend was playing his backup of Guitar Hero. He turns it on the next day, with the same disc in, and it doesn't boot. PSTwo wasn't unhooked and never moved, how can it go from working to broken? I opened up the PSTwo and none of the wires came unhooked and all the soldering looks clean. Any idea what happened? The PSTwo still plays his original retail games, just not any backups.

looks are one thing..... you might want to use a DVM and test it thoroughly, especially the CDVD points.

I checked the points with a multimeter for continuity and everything is checking out. I also removed the chip completely and soldered it back in, tugged on the wires, everything was connected fine. Backups still giving rsod and retail games are still playing fine. So then I take out the chip again and redo the entire mod from scratch, starting with new wires and everything. Still no go, it's the same situation. Is there anything I can do to troubleshoot where the problem is? Right now, I'm lost, it could be anything. I would really like to get this $50 chip working again.

sounds like the chip is toast.

just as an off remark, it's really amazing that modchip creators don't build any kind of troubleshooting features into their iron. chip should check if it's is not recieving signal on [insert point name here], and put some code on the screen. E.g. B or G, etc

I would imaging that kind a feature would be pretty hard to do with the chip not installed correctly to begin with. However the CC has something similar to this with an onboard LED that flashed different diagnosis codes.

@Textbook

If your sure the install correct, is the chip flashed?
