On a whim I bought a non-working Happy Fish v2.0 PCB for $18, when powered up the green LED on the board lights but no picture or sound comes up. I noticed there's a dipswitch with position 1 glued to the 'off' position, and the rest came set to off.

There appears to have been some solder work done on it, mostly to the electrolytic caps which look like they had been either replaced to resoldered, and surface mount resistors R11, 115 and 114 look like they had been messed with, poorly reflowed and slightly chewed up, I tried to redo it with some flux and my hot air rework station and while they look a little better the board behaves no differently.

I'm very early in messing around with this board but I thought I'd throw it out there to see if there's a common thing known to go on these boards. Also I don't suppose there's a schematic I can download from somewhere?
 
Those are basically a micro-controller running MAME or something, right? If that's true, then if you can identify the CPU, you should be able to get the chip docs and use that info to start your debugging.

I get the impression it uses a custom FPGA so I doubt I'll be able to find any info on it, but the rest of the chips I might be able to, hopefully the problem is in one of them. If the FPGA itself is toast then the board is basically a paperweight, the only way to get one is from another board.
