Recurring Monitor Problem

Thanks, Glen. I was just trying to avoid cross posting. And thanks for
your input.

HI DaffyD,
I think glee is probably right ... you have a loose solder joint or a
connector that needs to be disconnected and reseated ... has a little
corrosion (from time) coating it.

I am writing this mainly as a caution ... before you open the monitor and
look for solder joints to resolder or for connectors to unseat and reseat ...
let the monitor sit overnight, possibly longer. Why? To avoid getting
electrocuted. Monitors, like TVs, use a flyback transformer that put a high
voltage on the CRT. The voltage is on the front of the screen and is there
to attract electrons emitted from the electron gun located at the back of the
CRT. To help stabilize the voltages, the set uses some large capacitors that
store 'juice'. When you turn off the monitor, the capacitors take some time
to 'reverse' discharge through the electronics.

Good luck - BR.
