Question about Hitachi 43FDX15B 43" Rear Projection Television

1 Answer

Alignment breakdown.....? I was recently given a 43" Hitachi, because the owner has had enough of the same problem. The colors are all misaligned, making it look like you have three images, each of a different color. The owner had it repaired about 6 years ago, but the problem has returned. He vaguely remembers the part costing about $120.00 and taking less than 10 minutes to replace. Any idea what it may have been, and could I replace it myself? THANKS!! Swa

    The problem I am having is that green color is almost non-exixtant, as well as being out of line with the others. There is a slight green ghost at all times. I have cleaned the lenses and mirror. Also I loosened the adjusting wingnuts and tried to align and focus all 3 lenses. The red and blue look great, better than new. The only way to stop the green ghosts is to completely block the green lense. Any suggestions would be greatly appreciated. you can reach me at jhood01@yahoo.com

The most likely cause for this is a problem with the convergence circuit. This consist mainly of 2 ICs and a set of resistors. It does take some skils with soldering and electronics to replace the ICs and resistors. The 'convergence kit' is available from some web based electronic stores which includes 2 ICs - STK392-150 and a set of resistors. The authorized Hitachi supplier is Tritronics, but may be available at your local electronics supply stores. Hope this helps. clickace

The problem you are facing is a common problem in all rear projection TVs. It's called convergence. If you go into your menu there is an adjustment for it. if it doesn't move back into alignment then you have a more serious problem in the convergence circuit which will require replacement of components.
