Your TV most likely has one or more possible problems.

Problem #1: Convergence Chip Failure ( common problem )

Here are some of the most common symptoms and example photos of a convergence problem

  • 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.

Here is a quick test....

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

Try to adjust the red and then the blue convergence.



You should be able to move them up, down, left, and right.

If you can't move them in all directions your convergence chips are bad and should be replaced. This is a comcolors don't line up - 2c07611.png.

You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together a kits for most models. If you don't see a kit for your set send them a quick note and they will put one together for you. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, etc.


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.

What you will need to do is replace the coolant and clean the crt. You can get a repair kit from www.TvRepairKits.com that includes replacement coolant, photos. instructions, etc.

It sounds like you have a common convergence problem. to make this an easy repair go to tvrepairkits.com and order the complete convergence kit for your TV set it comes with the original replacement 's not those cheap aftermarket IC's or those popular factory reject IC's most people sell online or you buy online or in a local repair shop, also comes with resistors. pico fuses the thermal paste you need for the backs of the new IC's, full color pictorial instructions, and free live on-line tech assistance incase you run into a problem with the repair. Good Luck!!

RCA P52755BA 52 inch tv looks 3D

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
