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.

Re: TV started popping then died

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

My 50 inch dlp makes a crackling and popping sound, then starts to fade out and eventually makes a loud beeping sound. how do i fix this?

Look to see if this happens at all inputs--tuner and rear first.

This issue is not clear to me---sound is popping or you are hearing a sound from inside the set?

When I turn my tv on my speakers work for apprx 5 minutes than start crackling very loudly then go out.What could cause this ?

Hi, My samsung dlp 46 tv was making a loud crackling and popping sound from the speakers, I turned OFF all the volume
control on my tv from the menu the srs, the auto tune volume, the internal volume which, is the main one which silences the crackling sound immediately! But, you must have surround sound and play the tv volume through your surround sound and wa laaaa, it WORKS! The tv may eventually stilll go out before or if I decide to have it fixed. It is about 3 years old.

No picture (black screen); making popping/crackling sound

there is a possibility that the semiconductor in power supply side damaged due to electrical surge. more likely the STR IC of Diodes.
