Rca 52 inch tv model r52wh74yx66/power on problem/three lines

I had a problem with the convergence and replaced the fuse and it fixed the problem. it happened again 6 months later i replaced the fuse and it worked for a while then it went out but the fuse wasnt blow this time becasue the option was still there it just wouldnt adjust. Now for some reason it will work but when it goes out you have to unplug the tv for a while for it to work or beat the side and front of the tv(im serious) something loose mabye?

OK, so the last time i used the tv it was working fine then all of a sudden it showed 3 small horzontal lines green, red and blue then it powered off. When you try to power it on it turns on for a few seconds then turns off by it self. it will turn off and on by it self a few times and every time it turns on it shows the 3 lines then nothing.

any help would be awsome

My R52WH74YX66 HDTV shows in 3D and double vision


This is a common problem in these sets; if the set does not show "convergence" in the customer menu there are three pico type fuses on the deflection board and one is blown.


To be perfectly honest most shops do not like to fix this brand of set as the convergence circuit is spread across 3 circuit boards that are not available--all parts of course are RCA only and delays to get parts needed are common here.

Look in the customer menu and if convergence does not show, one of the protect fuses (really labeled as a "coil" is bad---these are usually located next to the High Voltage transformer and are usually tan in color about the size of a one watt resistor.


Let me know if you have questions as I am here to help.

Older RCA projection flickers and convergence out of whack


you can check the three little red fuses next to the flyback transformer , but then if not that then the convergence IC's will need to be replaced and the resistors checked on it for possible replacement
