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

This is a very common failure on these projection sets and a fairly simple DIY fix. All projeciton sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

Common Symptoms include....

  • 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.
  • TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.
Here are some photos of convergence problems.

Here is a quick test....

Using your original remote go-to the settings menu then goto the convergence section.

Try to adjust the red and then the blue convergence.

You should be able to move RED and BLUE in all directions - up, down, left, and right. And you should be able to get the grid straight.

If you can't move them in all directions or cant move them far enough your convergence chips are bad and should be replaced. This is a common problem.

Note: If you TV has as flash focus or magic focus button only try pressing the button. If it fails to fix the convergence your need to fix it. images on screen have shadows - 69189a5.pngor a fix

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses.
This is a a fairly easy DIY job if you are handy and can follow directions. You can get complete repair kits from TvRepairKits.com or click here. They have put together DIY repair kits that include the OEM parts and step by step photo instructions for each repair. If you are not handy or can't follow directions we would suggest calling a shop.

I have shadowing on the screen


Convergence bad? Try adjusting converge in menu and if it doesn't work, then an amp IC is bad. Possible resistors, too.

Hitachi Model# 43FDX01B is doing a double image.


You have a convergence problem, you will need to change the convergence IC's STK392-110, there is also 12 6.8 1w resistors that need to be changed, there is also 2 fusilbe resistors that may be open. You can probably Google the IC's as a kit and find them all in one kit.
You can fix this yourself and save about $300-$400 in repair bills.

Picture has a blue shadow


Hi,
Seems convergence out IC is fried in TV so it gives blue shadow.

Check out Convergence Out IC which you need to replace in TV, if you have enough experience of repair of big TV, necessary tools and know basic electronics.

43fdx01b arc at top of screen


Usually this means convergence ic's have to be replaced and possibly a few resistors on small convergence board. Sometimes it requires digital alignment after new parts are soldered in. This repair can cost 175.00-375.00.

Color alignment


It sounds like one of your convergence IC's has burned out and needs to be replaced. The defective IC will have to be replaced, the low-value resistors next to it checked and the convergence circuits realigned. If you do not have any experience working inside projection sets, allow a qualified tech to handle it for you.

Blue wave shadowing


The convergence Ics need replaced. In Hitachi, resistors and sometimes a coil needs replaced as well. The convergence/deflection PCB is available, but, the cost of that board is higher than having a servicer come to your home and repair the unit to component level. If you are not familar with this circuit, then call a servicer. Have them replace both ICs not just one. Make sure they are repairing to component level and not replacing the board. Hope this helps.
