Why does my hitachi rear projection tv has double image?


Are the double images different colors, such as red or blue or green? If so, the projection unit is "out of convergence, meaning the images are not superimposed on one another. That requires a convergence generator, also known as a video alignment generator.

I 53" Hitachi Projection TV and I get double


All projection TV sets have two very common problems. One is convergence ( 3D/Warped video) the other is CRT fluid ( Dull Video). Here are more details and solutions for both.

Common Problem #1) Convergence has gone out

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 pics of convergence problems.

Common 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 has double images around the edges of the viewing area.


Firstly check for correct colour registration at centre of screen. Look for coloured halo around white edges in centre area of picture. Use static convergence adjustment if necessary to correct centre of screen. Then follows an involved process of interactive adjustments to attempt correction of errors at the screen extremities. If these are out of adjustment range this is indicitive of a convergence drive fault requiring professional intervention.
I hope this information is helpful!

Getting double images on screen like outlines on images


Your TV has a failure of its convergence output ICs and perhaps some of the convergence circuit's other associated parts. The part numbers for the ICs are on the IC face. They can be purchased thru Hitachi or online at MCM Electronics.

Double image


Problem seems in convergence out section.

TV needs Convergence Out ICs replacement.

If you have TV repair experience and know good soldering work then you can give it try OR get help of qualified TV tech to fix it.

If you need further help, let me know.

Solution:

Your TV has a convergence problem. Here are some of the most common symptoms.

  • Screen looks 3D
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed in or warped.

Here is a quick test....

Using your original remote go-to the tv settings then goto the convergence or magic focus section.

Try to adjust the 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.

Its a fairly easy fix on the Hitachi sets.

You can get a repair kit that includes all the parts from www.TvRepairKits.com. The kit includes a photo instruction guide, original Sanyo STK chips, convergence resistors, etc.
Everything you need to fix it yourself.
