Question about Televison & Video

1 Answer

I have an 8 year old RCA P52940 rear projection TV that blew the input 5 amp fuse but now after I turn the TV back on the picture is not very clear and almost makes it look like you are looking through a balloon. And the figures on the screen have shadows making it look like you are seeing double vision.

The model number of your TV probably falls under the ITC-222 chassis design. Do a search based on that criteria and it should point you in the right direction. If I remember right, you need to replace FL231 on the deflector board though. Good luck

Picture flipping


The P52940 uses the 195 series chassis. The vert/hgt control is for vertical height. It adjusts the size of the picture from top to bottom. If your picture is flipping, it most likely means that something is wrong in the vertical circuits. I have seen fluid leak out of one of the CRTs and drip down on the vertical output IC, causeing the picture to go crazy vertically. The set should be serviced by a qualified tech experienced in the RCA 195 chassis.

RCA P52940 Television


The P52940 uses the CTC195 series main chassis. The most common reason for the set not to start up is a shorted flyback (high voltage) transformer. The set actually does try to start, but the computer immediately detects the extra current drawn by the shorted flyback and instantly shuts the set back off. The chassis should be checked and the flyback replaced by a qualified tech familiar with RCA projection TV's.

Rca 52 inch rear projection


This is a problem common with some RCA/GE TV's. The fix in the past was to install a capacitor between ground and pin 15 of the microprocessor which keeps a data signal riding on the video stream from muting the sound on most stations. By installing this capacitor, you would be disabling the closed caption feature so that feature would no longer work. An authorized RCA TV repair shop may be able to give you more information.
