Re: Asteriods G05 -802 Blooming screen

 From this description my guess is you shorted the HV anode directly to the
metal case without a 1 meg series resistor and fried the HV diode. This
happens a lot with the B&W monitors.

You can find these diodes in old B&W monitors that you often can pick up
for free at computer shops. Or old B&W TV's from the 70's...save the tube
as well if it is a 19" one, that will work in your Asteroids/Lunar
Lander....or raster B&W game.
