Had the same problem a couple of years ago, it is a defect in the TV. Contact Hitachi it's a convergence issue they will do everything to tell you it's wear but that is not true. I made a big deal about it and finally after contacting many people and doing much research on the problem Hitachi agreed to paid for the part which costs $360.00 Cdn. However, they did not pay labour (only $65.00). Hope this helps.

Red color convergence issue; Red lines are curved


This sounds like convergence output IC problem. convergence board would have to be removed - remove and replace 2 STK IC's and check the surrounding resistors. Shops usually $200-$400 Be sure to vote/rate me if this helped Thanks!

The picture looks 3D


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 projection 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. See below for a fix

Hello

red, green, and blue lines curve across the top of tv is cause by defective convergence STK IC or you have open resistor at convergence section. if you have defective RGB Color vertical ramp probably you have defective STK IC..

Curved red lines on the screen and the picture is distorted


This is a convergence problem that can be either poor solder connections on the convergence ICs or defective ICs. If you can solder you can fix this yourself. Update this if you wish to attempt the repair and I'll supply additional details and instructions.

Red will not line up


Good Day y'all;

First of all if the lights are on, that's good, the red light,LED's, indicates that there is power to the power regulator IC. The green lights, LED's, indicate that the DC voltages are present for those particular circuits. ALL GOOD! If off bad!
If after replacing the IC's with the 150's and still have color shift and all resistors are within 2% tolerance and adjustments were made properly. The digital convergence board may be defective.
If the picture is bleeding that normally is a gassy CRT, picture tube, and the bleeding changes with the brightness levels. You may try to rejuv but that may short life the tube.
Good Luck, get back if you want more details, Big Irish.
