I just picked up this machine late last week. I was told it operated the last time they had it on but its had been sitting unused for quite a time in their finished basement. It lights up and has static coming through the speakers.
Ive researched the machine and motherboard issues on this site. I'm confident the battery is toast. It is brown on the end under the plastic wrap that appears to hold the cells together. The board had a little corrosion by the battery. I've cleaned it and the surrounding areas with alcohol. While I had it out I pulled the roms, checked for corrosion on each, and reseated them. Upon holding the reset buttons and turning the machine back on I'm seeing either a single led lighting or all 4 leds blinking at the same time.
I've also checked different plugs and cables for bad connections. When checking one plug behind the hopper all lights and reels were energized but only when the plug was barely touching the pins and wiggled just right.
My first question is...would the bad battery cause the motherboard not to boot properly or are there other reasons I should explore?
Thanks! Looking forward to getting it going!
