Experiencing convergance problems in upper left hand corner on Samsung PCL541R mostly red shifted to right and down Bottom right half of screen is clear Do I need to replacer convergance chips?


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.

I own a 60PP9401 60 in. Rear projection tv. My red convergance was way out of line. I placed tv in the shop a while back,cost me $300 to get it fixed! Got set home, red still out of line,but not as bad. My...


This set has an advanced menu for adjusting the convergence and what may have happened is the shop adjusted it (It is done with an original Philips remote) and then not SAVED THE ADJUSTMENTS INTO THE SET'S MEMORY.

I can if you have the remote get into the menu and adjust and SAVE the adjustments. If the set is HD the convergence will have to be adjusted two times, once in regular and once in HD.

Let me know if you have questions.

Image on screen looks concave(middle of screen looks farther away than left or right side.)


Roseannmace,
Your TV is out of convergance. You'll probably noticed that there are red, green, and blue images. You'll need to determine if the problem is in the power supply or the convergance board. Usually, the convergance amps go bad and opens resistors. Do you know how to read a schematic and use a multimeter? You will also need to know how to remove the old parts and solder the new parts into the circuit board.

My tv screen is slightly tilted.


I belive it is a convergance problem. If there is a auto convergance function in the setup menu try it out. If that doesn't work I would clean the lenses with qtips and alcohol.

I have a Mitsubishi 55 inch rear projection tv, ws55819 on which the convergance is gone bad. I'm getting a concave picture with multiple colors and black lines with a blurred picture. this happens mutiple...


Your reference to concave picture suggests a high voltage problem and not convergence. If the raster can't scan from left to right , top to bottom, your having High voltage trouble. if your colors are not dropping on top of each other that is convergence. I would suggest it may be time to consider a purchase of the new HD set for the cost of this repair. good luck

Convergance problem


Hi, I`m assuming your going into the menu and trying to adjust convergence and the lines won`t align? If so the convergence IC`s have failed and that circuit will need to be checked to see which parts have failed and then replace them, probably time to call in a tv tech for that one, video-tek

Convergence is when you aim all three of the projectors, your tv has three, so that the images they produce all line up with each other. This usually doesn't generate a white line across the middle of the screen though, there is a button on the front panel of your set that automatically converges the three projectors, you can try using that.
