    i think i am having the same problem

    we recently had dish network hook up a hdtv receiver shortly after the red was out of alignment and you hit the majic focus and it will not fix the problem, also the tv will just turn on and shut off on its own this all starting happening after we hooked up the dish receiver

    let me know if anyone can help

If your model is 43UWX10B you need two STK392-110 Convergence ICs. and one each of the following 1watt reseistors. 3.3 ohm, 1.8 ohm, 2.7 ohm, 1.5 ohm, 3.9 ohm, and 2.2 ohm they are in order RK42, 46, 50, 54, 58 and RK60.
You can get replacement ICs and resistors at the following link and they provide free instalation instructions.

Colors will not converge on my RCA SRS Focus, model D52130. When I make an attempt to automatically converge, it says to reduce the light in the room. We even covered up the screen with a blanket at...


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. Repair kits with instructions are also avail from 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 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.

Blue will not focus causing "shadows". Magic focus will not solve the problem.


This tv have a problems call convergence,it dead.The tv convergence board the 2 STK convergence ICS and some or all it resistors are dead.These parts must be replaced to solved convergence problems.The shop will cost u $300-350 for parts and labors.

Too much red!


Do not adjust any knobs as instucted in the previous thread if you TV have a convergence problem. Doing so will only make things worse. The blog does however show you how to fix other common problems with these sets.

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 common problem.

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.

You can download the manual here. Insrtuctions for auomatic convergence are described. I copied the instructions below.

Automatic Convergence
Your HD Monitor’s picture tubes might have been disturbed during delivery or
after you moved the HD Monitor, causing the color in your HD Monitor to be
out of alignment. The colors adjust by starting auto convergence.
IMPORTANT: Auto convergence works best once the HD Monitor has
warmed up for at least an hour. If you've just unpacked your HD Monitor,
it's a good idea to repeat the Auto convergence function when the
HD Monitor's been running for at least an hour. See page 38 for more
information about Auto convergence.
1. Press OK to begin auto convergence.
2. When the auto convergence is complete, the Red center convergence menu
appears. The cross in the middle of the screen should be yellow. If it is not,
use the arrow buttons to move the red cross to overlap the green cross.
Press OK when adjustments are complete.
3. The Blue center convergence menu appears with a cyan cross in the middle
of the screen. If it is not, use the arrow

Convergence problem


your model has two boards that control convergence. One is the convergence board. the other is the convergence board power supply, usually when more than one color is off its the Convergence power supply that is bad. You can get replacement circuit boards at the following link.

Rca d52w19 convergence hell


Did you replace the convergence board or the convergence power supply board? usually one color will be a problem with the convergence board and more than one color means the convergence power supply is the problem. Ebay isnt a good place for boards as you never know if the board is good. You can get the convergence or the convergence power supply boards at the following link along with free shipping and tech support.

If you have a color (red, green or blue) that is bowed inward from any side, then one of your convergence IC's has cracked loose or burned out. There is no way to fix that manually - the IC and possibly a resistor must be resoldered or replaced, and that should be handled by someone experienced in repairing and realigning convergence circuits.

Adjust color convergence automaticly


I hate to tell you but if the colors are not aligning the way they used to is because the set has developed a problem know as a convergence problem,you should be able to align the colors (red,Blue)but if they are not going in is because the covergence IC's are going bad,If you are familiar with electronic service you can do some of the work yourself but sometimes still does require the help of a servicer to do the aligments from the inside,if you are not too familiar be safe and call for assistance.
