Question about Projection Televisions

1 Answer

I have a 3D effect with the colors on the left half of the TV

I received this Hitachi projection TV from a neighbor which was throwing it out due to the 3D effects with the colors on the left half of the television screen. He said the repair was costly but I have had the same issue with a TV of mine and had a good idea what was the possible issue. So I took the TV and am now trying to confirm if it is the part labeled STK392-110? Everything is functioning perfectly except for the left half of the screen and its tri-colors. If this part is the issue I have been told that some of these parts are not as good/dependable as others. How can I know that the part I order and pay for will be the best for this application too?

Thanks, BT

Thats a convergence failure and will require installing a convergence repair kit. You can get convergence repair kits for Hitachi models at www.tvrepairworld.com they come with the ICs low ohm resistors and the CD with repair instructions.

I have Hitachi 46F510 projection tv. Problem is that the picture is getting very blury. Cant find any thing in manual for bulb replacement. Hate to throw out the tv. ...


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 of a set that needs the fluid changed.

I'm getting an overlapping of two colors on the screen.


Hi,
It is common problem with rear projection tv and 3D type picture problem occurs due to failure of convergence output ICs, replacement of convergence output ICs will fix the issue and tv will again show correct converge picture as before.
Let me know tv model number written on back of tv if you want to fix tv by yourself as it needs soldering parts in circuit board expertise and if you feel uncomfortable working in tv circuit boards than local tv repairman will do this job for you.
Thanks.

3D effect where the blue color is a little lower than the rest of the colors. More noticeable on words.

Convergence problems are very common on all Projection TV sets including Sony, Samsung2_bing.gif, JVC, Philip Magnavox, Panasonic, Akai, Pioneer, Hitachi, Zenith2_bing.gif, and others. You can get a convergenece repair kit from the link below.

Common Symptoms include....

  • Screen looks 3D2_bing.gif
  • 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 flash2_bing.gif 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

3d effect only on half of screen


Projection TV sets are known to have two common problems. The first problem that is common to these sets is convergence failure. When this happens the TV will usually look 3D, Wavy/Distorted, etc. It may also shutdown and blink an error code.

The second common problem with Projection TV sets is dull video, halos around objects, white looking video, or red overpowers the screen. This is commonly caused by the fluid in the lens being clouded overs.
