I picked up a 4 player Demolition Derby yesterday that was in a barn. It worked before we loaded it, it worked for a little bit when we got back to the store.. Now it's not booting and this LED circled in this picture is blinking on and off. The power seems to go on and off with the blinking.
The battery was badly corroded but had not leaked onto the board yet, I just cut that off. I have not tried anything else other than reseating connectors to the power supply.
I can't seem to find any directions on testing an MCR III. Anyone know where they are some or anyone have any tips on what I should check?
Thanks.
EDIT: I realized i had the same power board in Crater Raider so I swapped it into there and it's fine. I'm now thinking maybe it's the Turbo Cheap Squeak board since that's where the led is blinking and the sound never worked right when it did work last night... I reseated all the chips and reflowed solder on it but there is no change.
