My mate's been offering me his JPM Monopoly quiz machine for a while, it's been in good working order and hasn't given him any problems but he's got newer machines and no space.

So I went and collected it today. It was on in his house, happily flashing away, we unplugged it, carried it carefully to my car, loaded it carefully, drove the 2 miles to my house and carefully carried it in.

I plugged it in a few hours later but it won't come on !
Power supply is running, various LEDS on the board inside are lit. The monitor is running with full HT but just showing a blank raster. No lights on the front of the machine or anything.

I checked all the supplies coming from the PSU, made double sure everything was plugged in tightly etc, but still no video to the monitor and no other sign of life.

I did notice that the back-up battery was just beginning to show signs of leakage, would a duff battery stop it from booting up?

Any ideas guys ?
