This is a coil, now a NOISY coil.. It is a common problem, and happens often. The whine is caused by current passing thru the copper windings and making them vibrate! A commonly accepted repair for this situation is to squirt some regular old super glue into the copper windings and let it harden for a few minutes..Viola! no more whine!

if you can get another one for a reasonable i would certainly consider that. the cost to get these lcd's fixed sometimes is not worth it. you seem to have more than one problem with the set.

Trouble turning on tv. High pitched noise/click.


The mainboard might have some loose components, or cold solder , or may be the filter capacitors are becoming faulty. Yes it is worth repairing, bring it to the repair shop. Cheers.

Sony Trinitron KV-19TS20 Screen displays purple static or awful image.


This unit needs a tuner. A new one from Sony will run over $70, so I doubt that it is worth it. It is possible that poor ground connections could cause something like this, but the symptoms seem a bit too severe. I think it is time to invest in a newer set.
