Use a unit called an electromagnet, and wave it around the TV. Your picture probably had a magnet too close to it.

You have a problem with convergence and all you may need to do is replace a fuse. Look up convergence for your tv model and hopefully you will get an answer as to where the fuse is located and how to replace it. Very common for RCA tv's

We have a RCA D52W23 rear projection TV. Now the color looks like it is in 3D. A friend has the same problem a few years ago and bought a part on line and fixed it themselves. What is the part and where...


projection TV sets have two very common problems. One is convergence ( 3D/Warped video) the other is CRT fluid ( Dull Video). Here are more details and solutions for both.

Common Problem #1) Convergence has gone out

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 projection 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 pics of convergence problems.

Common Problem #2) CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

Picture of a set that needs the fluid changed.

52'' Projection TV SONY


this is a problem with the convergence chip. you can try to adjust the convergence in the menu settings of the t.v.
pin cushioning will correct the curves, convergence fixes color seperation.

write the number down before changing them, in case you make it worse.

The picture curves in toward center of tv and looks like the colors are out of line.


These units had problems with there convergence power supplies. If the supply quits it will loose convergence correction. It could also be the convergence correction PCB itself. Have a repair shop check it out for you. Thanks

My rear projection 51mp392h has color distortion on the bottom third of the screen,it curves up in the middle. Is this a picture tube


Hello tj444,

This is not a picture tube problem. This could be what is called pincushion distortion. It is caused when the is a malfunction in the deflection coils and the inability to correct for the curvatures caused by the CRT. The pincushion distortion can also be caused by the degradation of the functionality of the convergence amplifiers in the TV set. I would suggest that you have a TV technician examine the deflection circuitry and the pincushion circuit, this would also include the convergence amplifiers.

I hope this helps,

Thank you,

Tv will not turn on


If it is a convergence issue, you can unplug the cable that connects the two boards all the way toward the front. If the tv comes on with a VERY bad picture(no convergence) then your problem is in the convergence ckt. If not, you could have problem with your small signal board. Also, the "yellow" problem you are having is that the cooling fluid in your blue tube is getting cloudy and needs to be changed.
