Question about if this is a fried PCB or not

knave:

I'm just a fellow noob but the first thought I had upon seeing your screen is that it's a startup screen and just frozen.  It doesn't scream fried (or baked) to me.  Just stuck.

I second the multimeter thread. I also reccomend reading up on your specific game board, there might be some troubleshooting tips in the manual and for some games you can even find the schematic.

Next I would gently reseat all the IC's and Roms (just press them to be sure they're in place.)

Level42:

1) Is that screen completely static ?
2) Is there a reset button on the PCB set, and if so did you try it ? Does anything change then ?

If 1=yes and 2=no, check out the reset line on the CPU (Z80 I think). If it's low, for some reason, the CPU is constantly reset = frozen. I had the same thing with my Centipede.
