I have this same problem with the PT51HX41E but in the convergence menu the green and red are allowed to move. but the blue on the right side of the screen is not allowed to move and it looks like its...


My first guess would be a bad convergence amplifier - this is common, although usually all three of the amplifiers in the integrated circuit die at the same time, which throws off at least two colors and creates a "bow-tie" effect. I surmise you have half of a bow-tie in blue only.

If you could look at the blue output waveforms with an oscilloscope, you would see right away if this is the problem (flat-line instead of sawtooth wave). It is possible that both of the blue convergence amplifiers are working, but one output is not getting to the blue deflection yoke.

Don't mess with the convergence anymore until you get this taken care of. Changing the convergence now will only make it harder to get it back to where it should be once the circuit is fixed.

Mitsubishi VS-50501A convergence problem. The image looks like a bow tie and the convergence will not align. This TV only has manual convergence. I already replace the STK391-020 ICs, it has 3 of them....


These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

Convergence problems are very common on all Projection TV sets including Sony,Samsung, JVC, Philip Magnavox, Panasonic, Akai, Pioneer, Hitachi, Zenith, and others. You can get a convergenece repair kit wiith instructions from the links below.

Here are some of the most common problems with these sets...

Problem #1) Convergence

Yours may have one or more of the following symptoms
  • Screen Looks 3-D
  • Colors wont align
  • Screen may look distorted or warped
  • No Audio/Video - makes a chirping sound.
Problem #2

Another common problem is dull or washed out video.
Your TV2_bing.gif may have one or more of the following symptoms....
  • Dull looking picture
  • White looking picture
  • Halos around objects
  • Red/Orange looking picture

One color Bow-tie Effect.


SAMSUNG Convergence Problem


It looks like blue convergence. Look at menu, select convergence and see if blue top is bent down on convergence adjust screen. Probably won’t adjust.

Some Samsungs have convergence IC’s on a separate convergence board in the back of the TV. Others have the IC’s mounted on the main deflection board. Either way the board has to be removed to get at the dud IC’s and associated burnt resistors.

You remove the appropriate board, determine if any resistors are burnt or damaged, replace any burnt or out of tolerance resistors, replace 1 or 2 IC's and re-install the board.

Now you have to adjust it to look like new.

If the unit has not been misadjusted and everything is OK now, running the auto focus may put the picture back to it’s previous stunning quality as it was before IC failed.

If after Perfect Focus it is still misadjusted noticeably, try the customer convergence adjustments. Operators’ manuals are available on web through searching.

If convergence can not be adjusted properly, you messed up chip install or resistors may be wrong value or open; or it needs major adjustment.

If you live around Calgary, Alberta try me instead:

http://calgaryconvergencerepair.weebly.com/convergence-explanation.html


Or try to the find the repairperson part of this website (on the Homepage) and search postal code. Maybe you will be lucky and someone from your area is listed for Projection TV repair.

Most rookies doing this job will cause damage and not be successful. They will pay double for someone to fix their mess or end up scrapping the TV. It is not a simple task. It is more difficult than batteries on a remote.

Good Luck
