Recently, my 1084S monitor which has served me faithfully for some time quit abruptly while I was using it. The picture and sound are now completely defunct, and the monitor makes a high-pitched whining sound when the power is turned on. Can anyone suggest what part of the monitor may have failed, and is it likely to be repairable?

Commodore 1084s ?
A high pitched whine from a switching mode power supply usually means overload or short circuit somewhere, usually shorted horizontal output transistor.
Here you go. Have fun!
