I have an old 1991 14" TRL VGA monitor which I would like to fix.
It was working until it started making a horrible noise. I took the cover off and could see the flyback transformer flashing over to the chassis. I cleaned out the burn marks and covered them with several layers of epoxy glue.
When I turned it on the monitor worked for about a minute and then it started arcing on the PCB that plugs onto the tube. There seems to be a spark gap on the connector itself.
Is there something wrong with the flyback transformer - voltage too high?
