Question about RCA P52939 52" Rear Projection Television

1 Answer

Green convergance problem

I recently went into the screen adjustments through the tv's menu to sharpen up the picture and clean up the colors. When I tried to adjust the green convergance, the green box it gave me was at an angle and not parallel with the sides of the screen. The blue and red cross-hairs are right, but because the green is skewed, it's impossible for me to get a good picture on all parts of the screen. Is there a way for me to rotate the box on the green convergance or is it an actual internal adjustment to the green can that needs to be made? If so, how hard would that be?

I also tried to get into the advanced convergance settings to try to get around the issue of the green being off, and found that my menu doesn't have that option, even though my manual says my model should have that. any ideas?? Thanks!

Sounds like a convergence amp failure. Depending on model, there may be 1 or 2 large Ics. Due to the delicate soldering involved, a tech should change these amps.Often the old part numbers have been upgraded, and small value resistors may need to be changed also.

How do you fix convergence on a sony tv?


hello!
If convergence in your TV went out suddenly and severely, there is nothing you can "adjust". That's a parts failure, convergence amplifiers I.C. chip(s) went south. Needs repair! Period! Minor alignments could be done by applying "flash focus" or "manual convergence" off "menu", if available.Some models have "flash" only option. Anyway, make sure there is no large metal structures near the front of TV or large speakers nearby. that could convergence to go out. Try not to play with any adjustments, if severe convergence problem. you won't be able to fix it right and will corrupt memory settings for "flash" option.
thanks,
Alex.

Projection TV sets have two very common problems. One is convergence ( 3D/Warped video) the other is CRT fluid ( Dull Video). Below are more details for both items. Also, complete repair kits with instructions and repair support are avail from site such as www.TvRepairKits.com

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 yourconvergence 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. The power light will blink. TV may also make a chirping noise.
Here are some pics of convergence problems.

What you will need to do is convergence. You can get a repair kit fromTvRepairKits.com . It includes replacement parts,step by step instructions, support, etc.

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.

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 common problem.

2c07611.pngSolution #1

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.

Blue, green, and red colors all off


I would suggest having a repair person come out to your place to fix this problem. I believe the convergence IC are going or have gone bad. I would estimate a $300 - $400 dollar repair bill.
