smash TV grey screen ?

Post by sven666 »

I have two smash TV PCBs, both have the same problem.

game boots up fine, all the roms check out, they both run fine in attract mode for any period of time.

when you start a game it runs fine untill halfway thru the 2nd screen when the screen turns completely grey, it remains grey untill you game over and then it turns back to normal.
if you start a new game it turns grey again halfway thru the 2nd stage and again back to normal once you game over.

what could be causing this?

both pcbs are super clean and 5V is good..
