Ok so not really part 2, because it still has a problem but the new power PCB rebuild seems to have gone well.

Voltages are good on the gameboard and it sounds like the PCB is starting, but I cannot play the game blind. So there is either a PCB fault or the PCB is semi working but there is no sound.

I hooked up the monitor and am still getting the following:

Space Invaders Problem

Space Invaders Problem

So I will build an adaptor to output the video of the Space Invaders to a Commodore 1084-D monitor so I can see what is going on.

Likewise I may be able to feed another RGB signal into the monitor to confirm if that is working or not
