    yes I will need the model number and chassis number off the rear tag in order to help you . As RCA used different chassis designs in the same model numbers.

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.

Picture problems


check for cold solder joints around the flyback transformer and a open pico type fuse very close to it. they are rectangle in shape and ususually the one in the middle of the three is the culprit. The problem is in the pincushion circuit

Bowed picture on rca p52955


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 TvRepairKits.com 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.

The issue is the Deflection board. The Fl1231 is open. The Deflection board needs replaced
