Hi again. When I touch the screen the green light on the touchscreen controller does respond. I also reset the game using dip switches 4 and 7 which went through the reset ok but still displays touchscreen controller not responding?  If I turn the machine on about 10-15 times it does boot to full game and works and plays fine til I turn it off. Any ideas what I can try next? Many thanks

Sounds a liitle strange that it works only occasionally....

If its not a bad connection maybe its bad caps on the motherboard?.... See any swollen ones?

Not much you can do here without any spare parts to try...

Sounds like you have a short or a loose connection in the touchscreen controller, or the glass overlay. I had a megatouch where one of the wires soldered to the glass tore off and was barely making connection. I had to gently resolder the wire to the glass overlay. Worked like a charm.

I had a touchscreen wire come loose before too but was unable to resolder it because the trace just melted

away when the iron hit it...if this turns out to be your problem... be careful and use the lowest heat possible.
