green dot in v5, really strange behavior

[aewysiwyg]

so here's the deal--I've put a matrix green dot in my v5 ps2. I wasn't exactly sure where to put the chip itself, so I put it over on the empty spot to the right of the board. This made somewhat of a tight fit when I put the metal plate back on, but everything seemed to work fine.

So on first boot, everything was fine. I tried a backup, worked great. I then updated to v1.93, and unplugged it, where it sat at home for a while while I was remodeling. Then I plug it back in, and it works, but won't load backups--just shows a black screen, after the ps2 home screen and MI logo.

So later I decided to flash back to v1.88, but the the ps2 decided that it didn't want to turn on at all. The power would come on, but nothing would show on the screen. The eject button wouldn't even work.

Then today, I come turn it on (hadn't moved the ps2 at all), and it works perfectly (using v1.88 firmware). I'm playing guitar hero 2, the game freezes, and when I restart, the system is dead again.

So now what's going on, is when I turn the system on, all the buttons work fine, but no output. Then if I reset the system, the blue light of the reset switch goes dead, and I can't eject any more.

Sorry this is very long winded, but any help would be appreciated (other than the generic "check your soldering"). Thanks much!

the chip may be shorting out, so I would put some electrical tape over the chip on the metal shield. Try that and see what happens.
