Question about Sony KP-57WV600 57" Rear Projection HDTV-Ready Television

1 Answer

Convergence and picture problem.

The colors at the 4 corners of the screen separate and then I get ghosts on those corners.I have tried auto focus and manual convergence but I can only control the blue and red crosses.These green crosses have appear on the convergence menu , at the bottom and at the top, mostly in the top and bottom corners and they can not be made to fall in line with the other colors.Where this green lines appear is where I get double picture and the colors separate.

Colors on tv are seperating. looks like double images.


Hi, Try the auto convergence or auto focus to eliminate the problem, if this does not work, you may have to get the TV repaired, the common problem are the power amplifiers that correct the color convergence, that is why you get color shades or ghosts in the images.

Colors on the screen are messed up with ghost HITACHI


Its not clear what kind of tv you have but it appears to be older rear projection tv with three picture tube. This problem does occur due to the convergence board going bad. Needs professional help to repair unless you know a lot about soldering ICs. Check out at www.fixurtvs.com for more answers on this problem, repairs and costs.

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.
