Sometimes and without any warning my Commodore 1081 monitor completely loses its picture. It's like somebody pulled the plug, the screen goes black, but the sound still works. After punching and hitting the monitor a little (just a little!
), the screen often returns, but only to go black after a while again.
When I opened the case I noticed a spool which is glowing when the monitor works correctly, but once the screen goes black, the glowing stops. Somewhere in the monitor there must be a loose contact that is causing this picture failure. Somebody told me that this monitor has certain solder spots that often broke, which could cause this problem. But does anybody know where these spots are?
Maybe somebody has experienced the same problem on his monitor or just heard about this problem and can help me here?
