Shadow of colors of picture in 3 D


This set uses two STK--392-110 ( you can also replace them with STK-392-150 which is a upgrade for the original type convergence chips)----You can buy both on Ebay for less than 13 dollars plus shipping2.gif.

Both chips need to be replaced and any damaged resistors around them located and replaced also--most of the time the set just needs both chips replaced and then adjusted.

If you cannot do this repair yourself--look in your area--most shops TRY to charge 300-400 for this kindof repair----I do lots of them here--did two Hitachi2.gif sets with this problem yesterday for 200-250 total.

MAKE SURE WHOEVER you get to do this changes BOTH CHIPS--SOME techs will come out and just replace one--in a short time the set will have the same kind of trouble again---Now is the slow time of year for TV repair shops---shop around for someone who will do this repair IN YOUR HOME--almost any good tech can do it in about 1 hour---if they say it "has to go to the shop" keep looking.

The chips are black(2 1/2 inches wide and about 1 1/2 inches tall with 18 pins) and will have the STK number printed on them in white--they are located on either one large metal heat sink2.gif with fins or two smaller heatsinks2.gif that are side by side.

Your TV most likely has one or more possible problems.

Problem #1: 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.

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

Picture of a set that needs the fluid changed.

A transformer blew in our neighborhood and now our tv picture is bowed and the colors are shadowing one another


Your conversion IC's are out, they cost about 40 dollars for 2, if you know how to solder, you can change them yourself, otherwise, repair shops usually charge 4 or 5 hundred
