Best to get a tech to verify problem--you may need a convergence circuit repair==change the STK IC's and then check convergence.Please describe symptom as you see it,if you want more assistance.

How to get in convergence set up mode sony tv kp51ws500


With the set off on the original Sony remote control press:

Display, 5, Vol up and power.

The set should come on with a lot of words and numbers on screen.

With 1 OR 4 you navigate until you see PJE on the screen.

9, and then 6 on the remote will bring up the convergence grid. You will see a grid with a blinking colored cursor--if it is green do nothing--3 will allow you to change to red or blue or green. IT IS A GOOD IDEA TO CHANGE THE SET TO A UNUSED VIDEO INPUT TO MAKE IT EASY TO SEE WHAT YOU ARE DOING.

Select red with the three button and navigate with the 1 or 4 buttons--enter button will allow you to adjust. enter again will allow you to navigate with the 1 or 4 buttons-- you want to get to the middle of the screen and then with 1 or 4 buttons navigate from the center around the screen.

You will find 1 moves adjustment in one direction and 4 in another. Go all around and adjust red first. Then repeat with blue.


When you are done hit Muting and then enter to save adjustments.

NOTE: some of these sets require the convergence be adjusted in the 4X3 which will also adjust in the FULL--if the set has the ZOOM AND WIDE zoom you will have to repeat the adjustment again in one of those modes to adjust Zoom and Wide Zoom.

Also if you have HD connection you may have to adjust it there also--many of these sets require it to be adjusted 3 times in the three modes.

IF convergence will not adjust in any one of the picture modes you have a convergence circuit problem and need to replace the convergence chips etc.

When you are done be sure to hit Muting and then Enter to save adjustments you have made. The word Write will appear on screen in green when you press muting and then in green when you press enter--it means you have saved the adjustments.


If you have questions or need help let me know.

The screen is just blue... apparently, the red ad green lights are blown. How do I rectify this situation? Sony rear video tv kp51ws500

Problem : Convergence Chip Failure ( common problem )

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.

Solution :

You need to replace the convergence chips and convergence resistors. Check the site have put together a kits for most models. If you don't see a kitfor your set send them a quick note and they will put one together foryou. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, etc.

I hope this will solve your issue.

Good Luck.

If my solution proves useful please accept it.

Auto Convergence not working

I'm assuming you were having picture quality problems prior to pressing the auto convergence button. If not then there could be a problem in that circuit. More likely I believe is a problem on the convergence board assembly or in the pincushion circuits. Also, check your owners manual to see if there is a manual convergence adjustment you can do.
