Colors are out of focus and magic focus wont fix


If you have tried the customer convergence menu/control and can not set the convergence you have a fault with the electronic circuit that controls the convergence of your 3 picture tubes this overlaps the 3 colors red, green, blue to create the proper color combination's of colors for a proper picture

Colors arched and overlapping


if the option for convergence is still listed under the setting section of the on screen menu, then you need a convergence power supply board. If the convergence option is missing from the menu you need the ITC222 convergence missing repair kit. You can get either one at the following link they include instructions for the repair.

I just received a Hitachi 50" projection Tv from a friend. He was the original owner and it appears after 8 years the picture quality went bad. After spending some time with the operating manual it appears...


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.

Convergence problem


http://www.retrevo.com/search/v2/jsp/mytrevo/myTrevo.jsp?page=man

You can download the manual here. Insrtuctions for auomatic convergence are described. I copied the instructions below.

Automatic Convergence
Your HD Monitor’s picture tubes might have been disturbed during delivery or
after you moved the HD Monitor, causing the color in your HD Monitor to be
out of alignment. The colors adjust by starting auto convergence.
IMPORTANT: Auto convergence works best once the HD Monitor has
warmed up for at least an hour. If you've just unpacked your HD Monitor,
it's a good idea to repeat the Auto convergence function when the
HD Monitor's been running for at least an hour. See page 38 for more
information about Auto convergence.
1. Press OK to begin auto convergence.
2. When the auto convergence is complete, the Red center convergence menu
appears. The cross in the middle of the screen should be yellow. If it is not,
use the arrow buttons to move the red cross to overlap the green cross.
Press OK when adjustments are complete.
3. The Blue center convergence menu appears with a cyan cross in the middle
of the screen. If it is not, use the arrow
