In an effort to get my WoW running I purchased 2 untested PCB sets (1 complete and the other missing the CPU board). I mixed and matched between those two sets and my set to FINALLY find a mix that worked...
...unfortunately about 5 minutes in to the game the playfield disappears as do the characters and the starfield starts blinking.
Sometimes I can get it to restart with a cycle of the power... but as of late it's been sticking to the blinking screen. I pulled the chips on the CPU board and cleaned them up... it worked great for a few minutes then back to the same issue. I try the other CPU board I have and the starfield is stable and the game plays but the graphics are all corrupted aside from the starfield.
After doing some chip swapping I determined that the middle top socketed chip on the CPU board (not the one with the heatsink) seems to be whats tripping out, though I am not sure if it's the reason for the blinking starfield. If I put one chip in either board the starfield works, game plays, but the graphics are all jacked up... put the other chip in and it plays fine...sometimes...sometimes it boots to the starfield blinking thing...and when it DOES play blind, it will, within a minute or two, drop the graphics off and the starfield starts to blink.
I've tried to increase the voltage from 5.09 to 5.16... and when I did that it worked after being a pain in the ass and not working for a few minutes...I figured "GREAT! It just needed a bump in voltage"...nope...as I finished the 2nd maze it dropped off screen and the damn starfield started blinking. A recycle did nothing (still blinked) so i got frustrated and came in here to bitch.
My only saving grace is that I have yet ANOTHER untested board set coming. My hypothesis based on pulling and replacing boards is that the issue lies in the CPU board... and likely with the one chip 0115 SX I think is what it's marked.
Any suggestions? Tips? Tricks?
