Panasonic pt-47wx53g red is out of convergence range


Have you moved the TV recently?, if so the red can(Red source) in the back bottom of the TV may have physically shifted in its holder, this is common when a rear projection tv is moved, jostled. Take the back off, look at the three cans,Red, Blue, Green, see if they all look like they are nested the same, bet the red is shifted a little.Good Luck with it!

I have a 42'' where the color in the top left corner seems to have separated, or shifted. The picture is ghosted in red and green in this area. It happened all of a sudden.


Your TV most likely has 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 www.TvRepairKits.com. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, email/phone support, etc.

SONY KP53HS30 rear projection TV screen suddenly turned blue....


The blinking 5 times is an error code meaning that the white balance has a failure. And because you are experiencing a blueish screen then your problem lies in the circuit of the blue picture tube or possibly the blue tube itself is starting to go bad.

Hi, I`m assuming your saying the letters on the screen have different colors (red, blue, or green) shifted to the left or right?
If so try going into the menu and adjusting your "convergence"
adjustments, basically, move the red onto the green then move the blue onto the green and the bar turns white, if one or more of the colors doesn`t adjust either up/down or left/right then the convergence IC`s have failed, this will require removal of the board and unsoldering the old IC`s and installing and soldering in the new IC`s, questions? e-mail me back, BMW Rider

Sony tv KP-61HS10 lenses wont align


This is common in those sets. One of your convergence IC's has stopped working and needs to be replaced. The convergence IC should be replaced and the convergence circuits realigned by someone with experience in Sony projection sets.

Sony bravia lcd tv-


If you are using a HD cable box or satelite with component outputs, be sure that all 3 cables ( green, red, and blue ) are making good connection.A loss of red or blue will cause color shift. Usually,if the tv menu comes up as the correct color but the picture dose'nt, it is most likely a signal problem.
