Too much red!

Over the last couple months the red tones in the picture are growing. I've tried to manually correct and using "Magic Focus" and nothing works. What can I do?

Do not adjust any knobs as instucted in the previous thread if you TV have a convergence problem. Doing so will only make things worse. The blog does however show you how to fix other common problems with these sets.

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.

Double images and colors are blurry .Blue,red and yellow wave coming up from the bottom of the screen on the lower left symptom is for busted convergence IC,you must replaced this IC in order that will works better again.STK 392-xxx ICs and it's associated resistor,this resistor automatically change value,can caused truoble even though you change the ICs.If you bring this to a service center they cost you $600 to $700,but if you buy the repair kit you can save more,don't wory it is very easy because there is intallation guide including in the repair kit.

These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

Convergence problems are very common on all Projection TV sets including Sony,Samsung, JVC, Philip Magnavox, Panasonic, Akai, Pioneer, Hitachi, Zenith, and others. You can get a convergenece repair kit wiith instructions from the links below.

Will not show red color in picture, magic focus shows red though


You have a projection light element out. I had the green element go on mine. I had a service agreement so a repair tech changed it.

Color shadows


Good Day, beekae;
No, there no other adjustments that can be made, the TV has had a Convergence Circuit Failure. The "CCF" is caused by that circuit, please call an Authorized Service Center and get an estimate. The avg cost is about $550.00. Good Luck, big IRISH.
PS or come back and I'll tell how to fix, if you are handy and own a good soldering station.

Magic focus, #5 Manual


Sounds like a Convergence IC problem, the convergence ics would need to be replaced. This can be done by yourself or a professional.
