Question about RCA D52W20 52" Rear Projection HDTV-Ready Television

3 Answers

RCA D52W20 has a shadowed picture.

The RGB on the television is not aligning. I ran the auto convergence and the manual convergence several times. The image got better, but the center of the TV looks pretty good but not perfect while the image gets more distorted as is got further to the edges. I adjust the RGB lenses and the picture got much better but is still distorted. When adjusting the RGB lenses is seem like more of a focus than an alignment. If I adjust the lenses so the center looks good, the image on the bottom left of the screen is shadowing slightly downwards and to the left, while the image on the bottom right of the screen is shadowing slightly upwards and to the right. The top of the television does the same thing as the bottom but not as much shadowing. I have a computer hooked up to my TV so I looked on-line and found color adjustment screens to see if it would help with adjusting. This is when I noticed what was shadowing. The red is shadowing downwards on the bottom left of the screen while the blue is shadowing upwards on the bottom right of the screen and green is just in between, this is the same type of issue left to right. Adjusting with black and white bars it is impossible to adjust it to a clean black to white line. What I mean is, it’s more like the white fades into red, yellow, green, cyan, blue to black. I’ve checked all of the fuses and carious if an IC went bad or if I need to replace a board. Any help will be much appreciated… oh… sorry for the essay.

Hi and welcome to FixYa,

Initially, this normally indicates failure of the convergence circuitry, 2 STK ICs involved, a couple of resistors, perhaps some pico fuses and alignment thereafter. Are you considering a DIY (do-it-yourself) repair? If yes, pls post back.

Pls post back result(s). Good luck and Thank you for using FixYa.

In that case if the manual tuning is not helping much u will have to replace the convergence ic on the board.

How do I adjust the convergance? I have a shadowing problem


Press menu on the remote then scroll down to setup then enter setup. The auto convergence feature is listed there which will reset it automatically. If auto convergence disappeared from the setup menu then you will need the RCA convergence option missing repair kit from www.tvrepairworld.com which does contain the instructions.

Shadow effect on picture. Picture is fine but there is a red shadow tint to everything (basically everything is written twice, but not in the same spot)

Rca r52wh74 - no auto convergance


The model number of your TV probably falls under the ITC-222 chassis design. Do a search based on that criteria and it should point you in the right direction. If I remember right, you need to replace FL231 on the deflector board though. Good luck

52 inch rca look like 3d picture


You have a convergence problem. The Red and Blue are out of convergence meaning they are out of synch, causing shadows. There should be an Auto convergence option either on the television or through the menu options on the remote. If this doesn't fix your problem, then there's a manual convergence option. Should that fail, a service call is in order. Best of luck!

Broken TV


you will need a convergence amp board or a convergence power supply board depending on wether its one color out of alignment or all of them. Let me know what color or colors are out of alignment and I can help you out with board selection.
