    your model uses two STK392-110 convergence ICs They are mounted on a large aluminum heat sink on the extreme right hand side of the chassis. You can get new convergence ICs at the following link with free instructions and tech support. You will need two STK392-110 Convergence ICs. They are usually very busy in the evenings as they have alot of customers so if you can access the site the first time keep trying.

Got new STK392-040 chips and picture is still distorted. Manual convergence still won't alligne all colors.


the 183 is entry into the tech menu===you need to test all the low value resistors around the convergence chips(only 6 or 8) and they will read low and a resistor with NO reading may be your problem.

Also these sets use a pico fuse going to each chip--either right with it or back at the source----know what a pico fuse looks like"

Im seeing duble words,how can i fix it?


Hi,
There should be a convergence adjustment on this set. It will have a "cross hair" type pattern
You adjust the beams so that the cross hairs turn white. I believe Green is not adjustable intentionally. The procedure is to adjust the vertical Red line until it alligns with the Green line. Then adjust the vertical Blue line until it lines up with the Red and Green. The line should turn White.
Repeat the procedure for the horizontal lines. When you return to regular viewing mode the double
images should be greatly reduced or eliminated..
Hope I've helped you,
Best Regards,
Mark

My hitachi tv's picture is distorted red and green like a 3-d pic


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.

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 from the link below.

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 - 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.

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 solution

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 know what you are doing. If you have never done this before we would advise calling a shop or if you want to do it yourself get a complete kit with instructions and support from www.TvRepairKits.com

Screen prob with Hitachi 51UWX20B red square


Maybe the best way to adjust the screen is with the manual magic focus..instead of letting the tv do the auto change it to manual and see if you can adjust the convergence yourself. I have this same model and once in the manual adjustment you want to make sure you see all white lines....if you seen any blue or red that is the color that needs to be moved towards the white line closest.

Once you think you have it lined up nicely hit "exit" on your remote and option 1....

Hope this helps you.

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.

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