Question about RCA D52W20 52" Rear Projection HDTV-Ready Television
My RCA R52WH74YX66 HDTV shows in 3D and double vision and the color red, green and yellow lines run across the front of the tv, what is the solution to fixing this?
There are 3 brown square-shaped fuses located on the power supply module located right beside the flyback transformer. Most likely one of those fuses are open. You will have to replace the open fuse and resolder the connections to the flyback transformer, which has a few pins that gets loose on bottom of board and makes that fuse blow. This is a very common problem on these rca's. I've had to fix a lot of them by doing this at our shop. I would definately start there.
From the back of the set, the flyback is located on the left corner closest to you on the board all the way to the left. It is large, either gray or black, and has 2 or 3 wires coming out of it. One of the wires will be very large in diameter and red. The brown square fuses are located just to the right of the flyback transformer. The values that you will need to replace them with is written both on the board next to the fuses and on top of the fuses.

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.
