Question about RCA P56950 56" Rear Projection Television

1 Answer

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

The green power LED probably is merely indicating that power is getting to your TV but the internal power supply is failing as evidenced by the loud "pop".

When i turn the volume up to(17-20) my sound cuts out and my speakers make a cracklin noise.i have bought new speakers and rechecked all wires.my speakers are rated at 50 watts rms and my stereo pumps out...


It seems you needs more power to maintain the level of good sound.Maybe the maximum volume is 30 - then the mininum is 15 and you can't hear any cracking sound. If you exceed 15 the minimum, as you said starting 17 - 20 you hear crackling sound .Then you reach ,what they called the "cliping level"so much distortion and crackling sound,your stereo too small to accomodate .You must add a power amplifier so crackling will gone and to fit your listening pressure...

Hope it may help you;

You have a bad audio output IC in the main board, you have a couple options as long as you don't use the sound from the TV...one is order a new main but if it was me I would take the back off and follow the wires that go to the speakers and unhook that plug.

You have likely almost but not totally fried a voice coil in your speaker. Most speakers get cooked from underpowering, not from being overdriven. What are the speakers rated for and what are you driving them with?

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. :)
