TV started popping then died

My TV started out by making a loud crackling sound from the speakers, then started going off and coming back on every 15 minutes or so. This went on for a day, then the next day, when you press the power button, it just makes a little humming sound, never powers up or gives a picture, then goes off. Before it quit working, the picture was perfect.

Sounds like the sound amplifyer IC in the set went bad and it holding down or blew out the voltage regulator. If your a tech first thing I would do is find the sound output IC and disconnect the main b+ lead and see if the tv will come on. if it did I would replace the audio output IC. If it didnt i would have to troubleshoot the Power supply for the missing voltage. if your not a tech its not advised to try to do this repair as there are no user serviceable parts inside this set. Seek A Pro to assist in this repair as there is hi voltage in this set even when its unplugged. Good Luck

I have a powered sub for my surround sound and every now and then its starts crackling and popping. i can make it stop by playing with the volume knob or even tapping it sometimes. my old sub did the same...

Does the crackling and popping sound comes only from the sub, or from the other speakers too? Try switching of to check. I think that it is problem on volume control potentiometer. In that case all the speakers must sound crackling and popping. If the problem is only in the sub you have to check its connections.

Continuous crackling from TV speakers

I'm sure you have figured this one out. TV itself is causing the problems.
The circuit board that produces the audio signal seems to be the problem.
Before you call the repairman, go to the web site Shopjimmy.com just to get an idea of what the parts will cost. That way he doesn't rip you off.

I hope I answered your question correctly. Please rate me. :)

Snap, crackle sound from Sanyo TV

It sounds to me as if possibly ya Main IC Amp Chip & OR the Output Capacitors are failing... Sometimes it is a sign of a power supply on it's way out... Either way it's time for a repair shop quote. Either that or it may be the speakers crossovers... to check this, if you can, try another set of speaker... see if problem is still there. If it IS, then it IS most probably as I said above.. If NOT then it may be one or both of the "Crossover Network" in each speaker...
