Question about RCA HD56W66 56" HDTV

2 Answers

I have a RCA 56" hdtv model # hd56w66 with an ITC222A chassis. The red convergence is way bent on the left side, especially in the top left. When I go into the service mode to manually fix it, the red lines are very bent and will not move. What could be causing this? Also, the picture will look fine at the start, other than the red on the upper left side, then it will flicker to "3d" and warped then go back normal. It will do this a few times then just stay warped and 3d looking. If I turn it off and back on it will look fine in the beginning then do the same thing. What should I do to fix this? Any help would be much appreciated.

    Thank you for your detailed answer. I have searched several times on all the boards and I cannot find any heat sink with STK convergence ic's on them. The only ones that are on the heat sinks have three prongs. I asked the question where are the convergence ic's in this type of television and someone answered it didn't have any because it didn't use them. If you have a picture, or could tell me exactly where they are, it would be most appreciated.

Your symptom sounds like a intermitant or damaged convergence IC.

There are two and large IC’s that control the convergence in a big screen set. They are secured to a very large aluminum heat sink. They will have a part number stamped on them that will start with an STKXXX-XXX, like STK392-110, and they are located on the signal board (on the left as you look into the back of the set).

Along with the convergence IC’s there will also be some associated components that will need to be replaced as well. There are some resistors that are part of the convergence circuit that will be open and need to be replaced. Most likely these will appear charred in the center. If you have an Ohm Meter or a DVM, check all the resistors that are close to the IC’s and you should be looking for either ones that have opened or have changed values.
There are also two resistors on the front of the board located in the middle that are fusible link resistors, these should be checked for opens and replaced if they are found so.

I would suggest that you contact a service center in your area for a complete diagnosis and repair, as this type of repair can get a little tricky. But if you want to repair the set yourself, just remember to be careful. The capacitors and CRT’s can hold a charge and may shock you.


If one of the convergence IC’s are found to be bad, I would replace them both, if one has gone bad the other may go soon. I usually order my parts from Andrews Electronics in California, they will have the OEM components that you will need.
Their site is http://www.andrewselectronics.com/welcome.aspx
And their phone number is a 24-Hour Order Desk: (800) 274-4666
I recommend the phone order so you can talk to the person about the different types of IC’s that are available.

I would also advise that the convergence IC’s be OEM or better, just because they are cheap does not mean that they are a good deal. I have seen the cheap IC’s fail after a short time, even though they look exactly like the OEM IC’s. I think that the bottom line is that you will get what you pay for when it comes to the parts.

You can also try http://www.tvrepairkits.com/ , I have not tried them yet, but they do carry OEM or better parts.

I hope this information allows you to resolve this issue.

My screen looks like its 3D.


Your tv has a problem with the convergence, adjust it using the original remote go to the setting's menu then go to the convergence section. Adjust the convergence color red and blue the green color is your guide you cannot move this green color, then you should move the red and the blue in all direction left to right, up and down. If you cannot move the red and the blue far enough the convergence IC is defective it must be replace in order to align this convergence. Feel free to send feed back good day and best regards.

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
