I have a sony projection tv kp-43ht20 and the picture has gone pink. Can you give me an idea what has happened? Is this a fixable problem? I can't afford a brand new tv at this time. Thank you for your...

Sounds like the convergence is out of adjustment....moving the set can cause this as well as components chaging value with age....The kp43ht20 is an older set and may not have the alignment setup in the menu as with the newer sets...but you can go thru the menu to find out...if there is one, then you can try to align the convergence...usually there will be a crosshatch on the tv...when aligning convergence there will be a blue setting and a red want to select red first and try to get the lines lined up as close together as possible on the red adjustment..then you go to the blue adjustment and do the same...the outcome should be as close as possible to white when everything is lined up properly

No,any colors lines mis alignments.The tv convergence board parts are dead.The 2 STK convergence ICS and some or all it resistors are dead.These parts must be replace on the tv convergence board.To solveved convergence problems.The shop,will cost u $300-350 for parts and labors.

Sony kp-53xbr45 please let me know step by step how to enter convergence service thank you


To enter into the convergence service of your sony, follow the steps below;
  1. Press "Menu" on the remote control. Use the up- or down-arrow button to move the cursor to "Setup" and then press "Return."
  2. Use the up or down arrow to move the cursor to "Convergence" and press "Return." This will bring up the convergence-adjustment screen.
  3. Press the up or down arrow to move the cursor to the line you want to adjust (either vertical or horizontal for red and blue) and press "Return."
  4. Press the up or down arrow again to move that line until it converges with the center green line and press "Return."
  5. Repeat to adjust the other lines until all three lines converge and are seen as a white cross.
  6. Press "Menu" to exit the convergence menu and return to the original screen.
You can as well follow these steps;
  1. Press the "Power" button to turn your TV on.
  2. Wait at least 30 minutes before you adjust the convergence in your television. This allows your TV ample time to warm up before you make the adjustment.
  3. Turn your TV to a cable channel or to an antenna channel with a picture that you can see. A music channel with a static shot of music notes isn't the kind of picture you need. Instead, look for a picture like what you would see on a movie, sitcom or drama.
  4. Press the "Flash Focus" button located in the front panel on your TV. You may need to open a hidden compartment on the front of your TV to access this button. The convergence will repair itself automatically after you hit this button. It may take several minutes.
Any of the two processes are detailed steps on how to enter your convergence service.

Take care

I can not get convergence to work.

you will need to install a convergence repair kit. The Sony type 1 convergence kit from is the correct one for your model, the kit contains the CD with instructions plus the replacement parts.

Green and red lines

Your TV most likely a convergence 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 are some photos of convergence problems.

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 will need to replace the convergence chips and possibly some convergence resistors and pico fuses. Its a fairly easy DIY job or you can call in a pro. If you want to do the repair yourself check the site Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, email/phone support, etc.

You need a remote that can produce the "DISPLAY" button on the Sony remote in order to get in service mode....(you could also carefully move the centering rings on the red CRT to line it up with the green CRT)

Convergence problem

Sounds like bad solder connections on the convergence circuit board. Better get it looked at before the damage becomes permanent.
