Area 51/Max Force Motherboard Repair

[otacon6530]

Howdy, I just purchased a motherboard for an area 51 machine. Honestly, it is just a backup board for my existing setup (I play through my lcd monitor), but I would like to get this secondary board working if possible.

This is the old board motherboard that has a daughter board with the roms. When turned on nothing appears on the screen and no hard drive activity. The rom light is blinking, which according to the installation instructions (TM-405) tells me that is the watchdog light and to check my eprom pins.

Here is what I have done so far:

• I took the entire eprom daughter board off and put it on my other board and video works. It complains the hard drive is not installed and when I install a hard drive it shows corruption but appears to play(The hard drive is for Area 51 only and the eprom are for Area 51 and Max Force, so this is expected and I deem the daughter board not the issue.
• All other stuff I am using works fine with my working board, so I can only imagine this is an issue with.

Anyone have any other general suggestions to help isolate the issue before I just start checking the ground and voltages on every chip to try to find an issue? I don't see any visual issues with caps or resistors.
