I got a 43FDX11B Hitachi TV and the image got kind of doubled on the left side of the screen. The problem did not occurred gradually. I realigned the projectors (I found that the crosses where not aligned)...


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.

I HAVE DOBBLE AND TRIPLE VISION HOW DO I FIX IT


This is caused by a blown fuse on the convergence circuit. There will be missing menu items in the service menu as well when this fuse is blown. You must replace the small block type fuse and then enter service menu and converge the television back to normal. This requires removal of the main board, unsoldering the component and replacement, and then alignment.

The screen looks like I need 3D glasses to see the picture. What part do I need to fix this?


Depends on the set, but it sounds more like your projectors have come out of alignment. Hopefully this isn't washout due to a failing emitter or projector. I would let a certified TV tech check the set for alignment since rear screen sets are very dangerous. All three projectors have their own HV cap and flyback, which triples the chance that you will get zapped.

Double check all the blue 3.9 ohm blue resistors in front of the two STK-392-570 CHIPS. If even one is bad--they can be checked like checking a fuse---the set will not adjust in some way. See other information......

If the set still turns on the protect fuses are good. It is also possible if the resistors are good you may have got a new chip that is bad--this does not happen very often but it can happen. When you see the other information let me know if you have questions.

If this has helped you rate this solution as I do this here for Free.

RCA HDTV HAS COLOR SPLIT ON SCREEN GREEN & RED


I HAD THE SAME ISSUE. I WAS LUCKY, MY TV WAS UNDER WARRANTY. THEY SENT IT TO BE FIXED. THEY REPLACED 2 CONNECTORS FROM THE PROJECTOR AND THE ON/OFF BUTTON. THE WIRES WERE NOT TRANSMITTING THE SIGNAL/ OR A SHORT IN IT. THEY REPLACE THEM ALSO. IT WOULD TAKE MY TV ABOUT 2 MINUTES TO TURN ON. THE COLORS WERE OFF. AND I HAD DOUBLE OR TRIPLE VISION. THEY ALSO REPLACE A FUSE IN THE PROJECTOR PART OF THE TV. THE FUSE ITS SELF COST ABOUT 275.00 WITH OUT LABOR. I DIDN'T PAY A THING I WAS ONE WEEK SHY OF MY WARRANTY TO BE OVER. EMAIL ME IF U THINK THIS HELPED. THANKS VERONICA.SANCHEZ@VETERANS.IDAHO.GOV
