Question about Hitachi 43FWX20B 43" Rear Projection Television

1 Answer

I have a Hitachi 43FWX20B. The green component of the picture is highly distorted. This happened suddenly yesterday. The Magic Focus does not have any effect.

    I should have mentioned that the Magic Focus stops during the green phase and the error code "5" appears. Does this add any useful information?

    Thanks. I'll give it a try. I am a retired Electrical Engineer with 35 years experience in the Semiconductor industry. I still know which end of a soldering iron gets hot.

    =======================================================================

    Yes, error code 5 shows that magic focus has not been adjusted as system control tried to move green convergence but did not receive correct signal through sensors mounted at sides of screen, due to failure of above said ICs.

    Please replace STK394-160 as above mentioned.
    Thanks.

Hitachi 43fwx20b Convergence Problems


These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the 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 wiith instructions from the links below.

Here are some of the most common problems with these sets...

Problem #1) Convergence

Yours may have one or more of the following symptoms

One half of picture is distorted


to create the total geometry in the tv is needed a system called Convergence.Convergence amplifiers are damaged in this unit, magic focus cannot work because magic focus works to level computer and controls the amplifiers damaged. this repair is for a technician because an adjustment is needed after the amplifier's replacement.

The convergence Ics need replaced. In Hitachi, resistors and sometimes a coil needs replaced as well. The convergence/deflection PCB is available, but, the cost of that board is higher than having a servicer come to your home and repair the unit to component level. If you are not familar with this circuit, then call a servicer. Have them replace both ICs not just one. Make sure they are repairing to component level and not replacing the board. Hope this helps.
