Roadblasters Cockpit

[Sirius]

Hi, I'm looking for some help troubleshooting a Roadblasters cockpit I have. The problem lies in the video display.

I've tested with two different monitors, do I know it's not the monitor.
I'm trying to determine if it's the main pcb or the cartridge. Thanks for any help.
Its also seem to be getting worse and worse. Now there is only a sliver of the video display showing, and it goes blank or black during certain parts of the attract mode. The game also refuses to go into test mode.

I'd say main PCB (since text looks OK, test mode should be readable!)

I'm suprised it won't go into test mode though, thats dealt with totally seperately. will it turn on in test mode ?

I have a similar fault on mine, but nowhere near as bad! (the road suddenly jumps sideways randomly in sections)

When I turn it on in test mode it starts up as normal. When I press the right thumb button on the steering control, it resets.
