I have a Terminator 2 board that boots but shows a U99 error. The U99 was pulled out and put into a Mortal Kombat; where it ran ok. The game will try to boot after self-test into a black screen with no sound but after 40ish seconds arnold schwarzenegger's face pops up (the hi-score screen). I can see no visible damage; any ideas on what to check first?
