The first thing I'd check is the Program ROMs. Pull 'em and read 'em in an EPROM programmer. Check the 32bit checksums against the MAME archives OR download and use ROMIDENT.

To use ROMIDENT you save a copy of the EPROM image to disk and run ROMIDENT against it. If it has the checksum in its database it will tell you what it is. If it doesn't then you take the checksum ROMIDENT gives you and search Google for it. If Google doesn't have it (which it typically will return a MAME page for the game) then either the ROM is bad or it's a version that there is no MAME dump for.

Beyond that, those big square surface mount chips with many many tiny pins like to pop those pins loose from the board. They'll need reflowing.

If I have a board like those on the bench that I can't easily identify problems with then those are the first steps I take in working on them. You'd be surprised at how many boards are fixed that way.
