Sorry--You will need resources to fix this one. STK392-110 IC's need to be replaced,afterwards convergence alignment in servicer mode may be needed.

I have a 60 inch Mitsubishi and there are light red shadows in the tv. is this an easy fix


It sounds like you need to re-adjust your convergence. The purpose of adjusting your convergence is to align your red, green, and blue colors. Moving your TV often causes this problem. I hope you get it going.

JVC AV-48WP30: CONVERGENCE PROBLEM!!! HELP!!!


U have convergence board issues. Sometimes over time the solder joints on the board go bad or develop minute breaks. U might try removing the board and resoldering every thing you can get it. U can also consider baking the board in an oven at around 270 degrees for about 8 minutes to melt all of the connections on the bottom of board.
Then remove, allow to cool, cross your fingers and see what happens.

Your TV most likely has one of two 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.

What you will need to do is replace the coolant and clean the crt. You can get a repair kit from www.TvRepairKits.com that includes replacement coolant, photos. instructions, etc.

Blue shadow and lines


This would apear to be a convergence issue ..sometimes you can go into settings and converge it manualy.. if this is to far out of range. a service tech will have to adjust inservice mode. if the convergence cuircits are not failing. if so then there are cuircits that will have to be replaced. is this just a blue shadow?.. is there green or red shadows. if not it may not be a major repair.
