I have an rca 52w20 rear projection tv. Lost the red and thats the only problem. What could be the cause


You more than likely lost the red tft panel in the optical engine. Repair would require a new optical engine. I have a tip at which explains the process and where to get the parts.

Thanks for using FixYa and for the great rating.

My 52" RCA P52937SG screen bows on the top and on

What you are describing can be due to a number of different settings.

Focus on the red and green guns
Sharpness on the red and green guns
Horizontal position and size
Vertical position and size.

Please consult a professional for adjustment on these items as they are all near or connect to parts that have Hazardous Voltage.

Toshiba 57h81 green will not focus

Typically this is a convergence problem and can be repair relatively easy. Refer to this video to determine if you truly have a convergence problem. Also make sure you use your TV's original remote to make this adjustment.

Big screen tv

Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

This is a very common failure on these projection sets and a fairly simple DIY fix. All projeciton sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

Common Symptoms include....
  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.
  • TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.
Here are some photos of convergence problems.



Here is a quick test....

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

Try to adjust the red and then the blue convergence.

You should be able to move RED and BLUE in all directions - up, down, left, and right. And you should be able to get the grid straight.

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

Note: If you TV has as flash focus or magic focus button only try pressing the button. If it fails to fix the convergence your need to fix it. See below for a fix


You will need to replace the convergence chips and possibly some convergence resistors and pico fuses.
This is a a fairly easy DIY job if you are handy and can follow directions. You can get complete repair kits from or click here. They have put together DIY repair kits that include the OEM parts and step by step photo instructions for each repair. If you are not handy or can't follow directions we would suggest calling a shop.

RCA P46921. Just changed flyback.

First, this assumes nothing else is going on to cause it. Here's what I did. Go to the 'green grid' via the v76 menu and go through the alignment there. Notice that there are red letters, blue letters, and a green grid. While you are in this screen, adjust the red, green, and blue focus watching the individual color's item until they are in focus. If they won't focus here, they won't focus and you have something else wrong (what I do not know). Then, return to normal programming, then select menu on the remote, then screen, then adjust projection tv convergence both horizontal and vertical crosshare. That ought to get it.

RCA 52inch TV

If the screen control for the green picture tube is set too high, then the colors will be greenish, there will be green where there should be black and there will be fine curved lines (retrace lines) in the picture. If you feel confident then you can open the set and look for the focus block which has the 3 focus and 3 screen controls. One row is labeled Screen and the green control will be the center one. Try turning that control down a little and see is the green background and curved lines go away. If they do not go away then there is something more serious wrong. If you do not have experience working on projection sets then allow a qualified tech to handle it for you.
