Re: Asteroids no video

That sounds like a HV failure. Often the HV diode. Condensation forming on
the HV lead might have drawn to much current through it. I would have to
wonder if this is the customers fault. After all you should NEVER plug in a
electrical device after it has been outside in the cold until it has warmed
up to ambient room temperature. Did the customer plug it in as soon as it
was brought in? There is the problem. The solution is to find out if the HV
cage is producing secondary voltages (400VDC and 90VDC come to mind) and if
so, then you need a new HV diode. If you find a B&W TV from the 70's it
should have this diode in it ready to be stolen and used in the game...
