I just picked up a Williams World Cup pinball machine for $200. All main capacitors have been replaced and the game is only missing 1 part (goal spinner) and it works about 75%. It powers on does the self test and I can get it to do its diagnostic and everything works but I can't get it to go into attract mode let alone play it. I have run the cpu onboard test and the prom test and it passes. Just looking for some suggestions I think it was worth the $200.

That's an...interesting...paint job on that cabinet; better than just a solid color I suppose!

Ball in the trough, and trough switch appear to be working? Batteries installed on the MPU board, and battery holder in good condition (not rotted by battery acid)? If you turn the game off/on quickly, does it then come in attract mode?
 
Battery holder seems to be good with new batteries. When you say ball in trough what do you mean? The ball right now is between the flippers next to a kick switch. When I turn it off then on it powers on but the credit / player display show 01 04 all the time. I can run the diags and everything seems to be working. Could it be the connectors joining the MPU board and driver board together. Here is a link to my photobucket album for the pin. Please feel free to leave comments if you spot something.

Your battery holder has a busted terminal, left side bottom. If it's booting into diagnostic mode, my guess is that the battery holder is the only problem on there.

I'd suggest either a remote battery holder or install an NVRAM (Looks like the 5101 is in a socket already, would be an easy update)

Alright I took out the driver board and MPU board to replace the 40 pin connector and battery holder and I found this on the left side of the driver board. Is this acid damage. Is the board toast.

This is the back of the board.

Nah, that's not acid damage actually. The green solder mask on that era of boards tends to bubble and flake off like that, almost every board has it to some extent, and it's nothing to worry about.

Looks like the board has seen a fair amount of repair already, and one of the transistors looks a bit ugly, but nothing critical that would make it unrepairable by any means.

Not an electrical issue, but when looking at the flippers I see the roll pins sticking up above the play field. It almost looks like someone raised them up so the flippers would stop against them. I've never seen a machine where the roll pins were not flush with the surface of the play field.

Just looked at ipmdb... There are pics of two world cup machines on the site one with the roll pins sticking up, and one with them flush to the playfield.
