I have an RCA HD52W59 HDTV and my kids were watching the other day and all of a sudden the screen went bad. The sound is ok and you can still see the picture however it looks like your watching in 3D...


This is normally an easy fix. I've fixed several of these. When you get the back off of the set, there are 3 small square brown fuses located at the back left corner of the set, if looking at it from the back. They are located next to the right side of the flyback transformer( the large gray or black thing sticking up with the thick red wire coming out of the top). One of those fuses will be open and needs to be replaced, and the pins on the flyback transformer need to be resoldered on the bottom of the board. They will come loose and make the fuse blow. This will fix the problem 95% of the time on this set.

Double Vision & Bowed Screen


Chances are that the convergence amps are bad.
If those are mounted on a separate board, replacing the board would be the easiest thing to do. Running the magic focus or touching up the convergence in the customer menu may be required.

I have a convergence problem. My Sony KP-65WS510 has a picture that looks like 3-D and bows at the bottom and top of the screen. I already replaced both the IC's STK 392-560 (2 qty.) and check all six 3.5a...


You have a convergence problem. Here are some of the most common symptoms. 
Screen looks 3D
One or more colors can't be adjusted when using the convergence menu. 
Screen is bowed in but stationary.

Here is a quick test....

Using your original remote go-to the tv settings then goto the convergence section.

Try to adjust the red and then the blue convergence.

You should be able to move them up, down, left, and right.

If you can't move them in all directions your convergence chips are bad and should be replaced. This is a common problem. 

>>>Solution<<<< 

You need to replace the convergence chips and convergence resistors. 

Check the site www.TvRepairKits.com. They have put together a kit for your exact model. The kit includes a photo instruction guide, original Sanyo STK chips, convergence resistors, etc. Everything you need to fix it yourself.

Help with RCA projection TV P46812BL (chasis ptk195AA)


You have probably blown one of the convergence ICs. Effectively the easiest thing to do is replacing the whole convergence board, so that no soldering is involved.

Here you can buy a replacement convergence board, just select your model.

Let me know if you need further help.

Distorted Screen for RCA HD56w66


convergence is the problem. first question do you have convergence in the customer setup menu. if you do not it could be a special small fuse if you do have "convergence" in the setup menu then you most likely have a convergence power board issue. and generally they are replaced. in our shop such board replacement average 124 labor and about 100 for part. if the fuse bout 15 for part and 80 for labor. there are solder connection that cause the blown fuse
