Messed up Ninja Gaiden

[Jarofmayo]

Got a Ninja Gaiden board today, powered it on and got some funky rainbow stuff going on screen here:

Board looks clean/fine. Any ideas on where to start?

Probably the usual to start. Check the voltage on the board for 5v-5.1v and reseat the socketed chips.

Edit: maybe add some board pics?

Try playing it to see if it's just the graphics messed up. Insert coin, press start. See if music is fine etc. if it doesn't play at all, verify the program roms first.

did you have your jamma harness plugged in all the way?

Harness is plugged in nice and tight.

Checked the voltage on the board, and it's running at 5v volts. Haven't tried reseating the chips yet, but I did take some pics of the board.

Nothing seems to happen when I insert a coin and hit start. Forgot to mention the audio isn't playing either besides a faint sound pop every few seconds.

Here's the board pics:

Another update, reseated the roms 1,2,3,4, and the one in the blue socket. Still getting a rainbow mess of glitches on screen, but the buzzing sound it makes is louder now. Any other ideas on where I should go from here?
