Your TV most likely has fone of two possible problems.

Problem #1 - Failure in the convergence circuits. ( 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 tmy tv is showing alot of red with blue blotches ac - 0667c5f.pngdirections your convergence chips are bad and should be replaced. This is a common problem.

0667c5f.pngSOLUTION

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.

Problem #2 CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

Blotches on the inside screan of an lg 55 inch tv

Any external damage? Any chance of hit by a ball or some other while children play? If not, try connecting some other input such as a DVD player and see. If you notice the blotch at the same spot again, the display has got into a problem and might have to be replaced, if you really find it irritating.

Burn-ins?

It sounds like your light engine is on it way out. I would have this verified by a service center. Very costly to replace. They will probably try a new lamp first.

I got this Sony KP-57WS500 57 in TV for FREE from a guy posting it on craigslist because he saw "BLUE SWIRL LINES" also knows as "Retrace Line" on the screen and he went to several repair people and got high repair costs so he was giving it away for free, but i found a guide that tells you how to adjust the tv to make the blue or green or red lines go away, aparantly the line show up because the voltage on the color ray gun tubes that get out of adjustment. Here is the Link to the REPAIR GUIDE. http://www.somelifeblog.com/2007/06/sony-projection-tv-red-line-repair.html
