Rca 52 inch keeps shutting off and picture is curved
Today i turned on the tv and the picture is curved looking and it keeps shutting off.. we took off the back and cleaned all the dust and this did not fix it..Picture quality is still excellent but doesnt look right when its curved.. It almost acts like its surging when it shuts off then comes back off but the menu doesnt show up its just a black screen then goes back to the show and will be normal for awhile then goes back to being curved.
This tv is only 3 years old..

Re: rca 52 inch keeps shutting off and picture is curved
The curved picture indicates failing parts in the pin amp section and probably some faulty parts in the scan amplifier sections. The set is being turned off by the uPC because there is a fault indicated, and it is going in to protect mode.

Most likely the Horizontal output transistor has shorted. When it shorts it causes the power supply to chirp. This is a common problem with this series of TV. Have a shop check it out. It should not be real expensive.
You have a problem with convergence and all you may need to do is replace a fuse. Look up convergence for your tv model and hopefully you will get an answer as to where the fuse is located and how to replace it. Very common for RCA tv's
Your TV is overheating.. easiest remedy is to point a fan at the back of the TV or... clean the inside of the TV, Im sure its full of dust and stuff... this prevents air circulation inside the TV thus creating more heat...
