I picked up this cabinet for nothing and need to do some repairs to get it running. Aside from the outer lights (Marquee) the game would not power up. I got into the back and took a look. There was power to the control board ON TOP of the CD-Rom drive (red light was on).. but I noticed there was no power to the CD unit in the housing underneath the control board. I tried hitting the POWER button on the CD-Rom and got a millisecond of life but then it blanked out again. I reset the game a few time (off/on) and tried this over and over. It finally stayed on and I heard the POST beep of the CPU unit.
Went to the front of the console and stuck on the POST screen with a CHECKSUM ERROR but it gives me the good ol' "PRESS F1 to continue". Is there a keyboard input somewhere I can tie in and get past that POST?
On a second note... is this an issue that can be fixed PERMANENTLY with the upgrade of a board? I tried looking for Ultracade and they are defunked and I dont know who is picking up on the repair parts, support.
Anyone have any thoughts? I appreciate your time !
