Your TV most likely has a convergence 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 are some photos of convergence problems.

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 convermy hitachi ultravision have double vision and - 0667c5f.png are bad and should be replaced. This is a common problem.

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses. Its a fairly easy DIY job or you can call in a pro. If you want to do the repair yourself check the site www.TvRepairKits.com. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, email/phone support, etc.

The convergence on you television has come unaligned, you can have it realigned by a television repair professional. If a problem still exists the ic's on the convergence board may be bad in which case they will need to be replaced.

How can i fix my hitachi ultravision it has green and double vision on top of screen


If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Check the cables, connectors and connections.
Take it to a repair shop.

My hitachi ultra vision television is giving a double picture


This is a common problem with rear projection TVs. It will require pulling the convergence board out of your set and replacing two large ICs and several 1 watt resistors. It can be fixed no other way.

DOUBLE VISION AT TOP OF MY SCREEN. DISTORTION.


Good Day, wars;
You may have a poor seated cable connector. Unplug TV from A/C, remove back look for a large black connector. It connects between the Main Digital Module and the Drive PWB. Re-insert both ends several times to make better contact, use contact cleaner if have but not always needed. Good Luck, big IRISH.

Double vision with a lot of yellow color


This looks like bad convergance. If only one color is affected it may be one of the convergance IC's. It is best to replace both IC's though. If you change the IC's then check the resistors next to the IC's. Use the exact part numbers. STK392-110 IC's can be upgraded to a STK392-180 for better heat strength. (That is why they blow, too much heat generated. Use a liberal amount of Silicone Heat sink compound.) A shorted IC will usually blow a resistor. If a bad resistor that isn't changed it will look like the new chip is bad. Make sure that you use the same wattage and the exact value (Ohms). Your convergance will not be right with an off value resistor. This info works for about any other brand Projo TV. Cheers, Lee http://www.crazycomputers.com

I Have a Hitachi Ultravision projetion TV Ned help to fix it.


This sounds like the solder joints on one of the convergence output IC's have cracked loose or the IC itself is defective and quitting when it warms up. The IC needs to be either resoldered or replaced.
