Most likely the TV has a power supply related problem. It's possible that it maybe a bad capacitor or transformer on the power supply board. The most common board to go bad is the Backlight Inverter Board. That part supplies power to the screen. But, I can't say it's 100% the problem because I can't actually look at the tv over the internet. I can only make guesses with the symptoms.
You have a few choices:

1. You can try leaving the TV unplugged for 30 - 45 minutes so the TV can discharge and reset itself.
2. If by chance the TV is still under warranty, go that route.

3. If you have some electronic experience, if you can find and purchase a Service Manual over the internet; It will help you diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you circuit diagrams, test points, and part# lists.Usually, cost under $20. And most cases the new part cost less than $15.

4. Pay a TV shop to do the repairs. It maybe costly, but get an estimate of how much they will charge. That way you can decide if it worth repairing or replacing the whole TV.


I hope I shed some light on the subject for you.

TV on, sizzling sound, smell smoke, picture goes out but TV still on


It could be any number of components on the main board/power board which could be frying..But if you are hearing a sizzling sound, it could be something probably like a capacitor or the board itself. Difficult to say unless it is opened. First thing, though, is unplug the TV from the mains as a precaution against fire.
Since you are a technical guy, it shouldn't take you long to figure out what the components are thats burning. However, if your TV is under warranty, I advise against opening up the set as that will void your warranty. However, if its not under warranty, go ahead and open up the set and see what components need replacement, or replace the whole power board itself (if you are comfortable with electronic soldering/desoldering).

Cheers!

ProScan PS32500 32"-Picture has white static line & Static/burning smell


It sounds like the circuit board is arching over somewhere. It could be as simply as cleaning and digging out the carbon mark to stop the arching. This is most likely the screen or focus voltage causing this, if there are no parts that have broken down. This will damage the printed circuit board and make things worse the more you let this cook. This could be dangerous for you to mess with because of the high voltage present, so my best advise would be to get this into the repair shop as soon as possible before this board burns up. It should not cost all that much if the CRT board can be repaired. Good Luck
