Question about RCA P56950 56" Rear Projection Television
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
