Title: -Commodore 1942 Monitor goes Black Screen
Post by: Drummerboy on August 31, 2010, 03:48:20 AM

Hello,

i have here a C=1942 Monitor, work fine.. But 2 times, the monitor goes black screen, then if you turn off and turn on again, all returns to normal..

Anybody happen something like this with any C=1942 Monitor too?.. I do not think that is about to die, but you never know what could happen.

remember .. do not pass any other problem, such as fading, or toher problems..

Comments?..

regards.

Hi I had the same problem a number of years back on my 1942, its was simple enough to fix. The problem was some dry joints on the Line Output Transformer and a quick resoldering job fixed it. Sound like thats what's up with yours. If you need the service manual for it just let me know and I'll send you it in PDF format.

Hi,
If the screen goes dark and you still have high voltage on the screen (you can feel "static" when you touch the screen), check the heater circuit on the small PCB on the back of the picture tube (on some models the two pins are labeled "H"). The solder often cracks. If not most likely a poor connection on the flyback transformer.
