Question about Protron PLTV3250 32 in. LCD Television

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

I woke up to find my wife searching for the source of the smoke with a flashlight on our TV. I came to find that the smoke was coming from the what I think is the power board? I'm not sure, I'm a technical guy. The sound and the TV still work, but the picture goes out immediately once the TV comes on? Is it the same problem with the burn diode or is it something completely different?

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!

You need to look inside to see which board has smoked, I will suspect the power supply module. This is poorly designed TV!

Could be the signal board has a bad cap, in this case it sounds like you are getting intermitten power to the inverters....when the tv goes down and of course you have audio....Shine a flashlight on to screen and see if you have a picture...look carefully. If this is the case..you have the above problem!

TV was working just fine.. no issues at all.. turned TV on.. and got a click click click sound... no picture, no sound (other than click) smelled like something was hot. TV is about 7 years old. TIA.....


It sounds like it is time for a new TV, unfortunately. Nowadays you can get a new one for about the same as your repair costs would be. If you smell something burning you probably smoked a circuit board.

I have the same issue. If you click the source change button it will come back- (whilst on the wrong source) for a while. I think your getting inferior LCD panels. Try smelling at the top  of the tv, see if it smells a bit burny.
