Kp-51w5510 convergence intermitten

I am having a convergence problem . i pulled the back off and taped in the area i thought was the convergence board and the problem cleared up. now it is back agian. i have been a tv repair person for over 16 years but haven't worked on any sence 1990 . I have found that these types of problems are usually a loose connection as a solder joint broken circuit board plugs and pins have come loose by just heat and cool over time and then you can find just a broken wire w insulation still intact. the set in question is not mine but my daughters inlaws. Can you direct me to where to look for the convergence board or circuitry that controls the convergence. or where i can get a sams for this tv.

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.

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 from the link below.

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 - TV may also make a chirping noise.
Here are some photos of convergence problems.

Here is a quick test....

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

Try to adjust the red and then the blue convergence.

You should be able to move RED and BLUE in all directions - up, down, left, and right.

If you can't move them in all directions or cant move them far enough your convergence chips are bad and should be replaced. This is a common problem.

Note: If you TV has as flash focus or magic focus button only try pressing the button. If it fails to fix the convergence your need to fix it. See below for a solution93a1209.pngCONVERGENCE SOLUTION

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses.
This is a a fairly easy DIY job if you know what you are doing. If you have never done this before we would advise calling a shop or if you want to do it yourself get a complete kit with instructions and support from www.TvRepairKits.com

Hi,
Problem cause is red convergence output chip failure that will be replaced to fix the issue.
If you have experience of electronics stuff repair and can replace parts in circuit board as it requires soldering work with proper tools then can replace convergence output IC in your tv by yourself.
Let me know if you have additional question.
Thanks.

Blue converence was intermitten now out on sides


If the IC's say have STK printed on them, then they are the convergence IC' s. should be three of them, replace all 3 , and the burned green coils, sometimes these burn as they supply the volts to the STK's. good luck, be safe..

Tv Problem


Sony TVs generate an error code. The front panel LED (red) will flash anywhere from one to eight times which can isolate the problem circuit. It is not always accurate.

If you have a test meter which can read DC voltages and resistance in ohms, you can locate the problem area. If you lack the expertice to do so, contact a sony authorized servicer. If you have the ability, start by checking fuses on the "G" board ( power supply board) and the "D" board or deflection board.

A major problem area in this TV is the convergence circuit. There are six fuses around the convergence output ICs on the "D" board.

If any are open, replaces the output ICs.

Convergence IC replacement


some have plastic clips that need to be pressed back to release the board. There should also be 6 screws holding the D board to its frame.
