Question about Hitachi 57F500 57" Rear Projection HDTV-Ready Television

2 Answers

Intermittent loss of red color

I have a 5-year old Hitachi 57 inch rear-projection TV.  In recent weeks, we have episodes lasting a few minutes to hours in which the red colors are lost from the image.  Faces are green.  Blue colors are still normal. But there is no red.  The problem resolves on its own, but is getting more frequent.

    This is a rear-projection TV -- not DLP. Is there a separate red color tube? Can I replace this myself? Where can the part and instructions be obtained?

    Thank you.

54inch Hitachi TV has double figures and colors red, yellow-not normal. Set approximately seven -eight years old. Lost remote control and direction book in moving. Is the set worth getting fixed? Generally...


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. This is called convergence.

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 Sony2_bing.gif,Samsung, JVC, Philip Magnavox, Panasonic, Akai, Pioneer2_bing.gif, 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

  • Screen Looks 3-D
  • Colors wont align
  • Screen may look distorted or warped
  • No Audio/Video - makes a chirping sound.
Problem #2

Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

  • Dull looking picture
  • White looking picture
  • Halos around objects
  • Red/Orange looking picture

You can see some more examples and find a fix here

The color is screwed up


The projection TV has 3 color guns that focus to produce a single image. The 3 colors are red, green and blue. It sounds like the blue gun went out. You should be able to remove the back panel of the TV. If doing so, use caution as there is a mirror attached to the back panel. Once removed, you can confirm that the gun is not working. The fix, unfortunately is neither easy nor inexpensive. The problem could be simply a poor connection to the circuit board up to needing the replacement of a new light or perhaps a new gun. Unfortunately, there is no magic button to press and nothing you are doing wrong. This is a very nice TV and it may be worth getting an estimate to repair it. Or, perhaps this is a good excuse to go out and get a new 50" plasma! Hope this helps. If you can think of anything else I should know, please comment.

All color guns out of alignment


Needs convergence amps replaced. Sometimes resistors burn and need to be replaced. This repair requires soldering/desoldering equip. and a trained eye, but usually can be done for 175.00-325.00 at a reputable service center. Good luck, Russmann.
