Question about Hitachi 53UWX10B 53" Rear Projection Television

1 Answer

I have a Hitachi 50EX8K. I believe I have a convergence problem. Colors are blurred, and the picture is pulled in near the center at the top and bottom of the screen. It would happen rarely, and recover quickly (within 5 minutes), this time it has been days. I've cleaned the lenses and mirror. All three lamps are on. Any suggestions?

Sounds like a convergence failure, it was initially probably just loose connections but now it needs new parts, here is a tutorial I made:

Let me know if I can be of further assistance.

Alghin red green abd blur colors


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 Sony, Samsung,JVC,Philip Magnavox,Panasonic,Akai2_bing.gif,Pioneer, Hitachi,Mitsubishi,Zenith and others.
You can get more information and a DIY convergenece repair kit with instructions from the link 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 - TV Shuts down - May also make a constant 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

The picture is blurred, words are blurred . . overlaid with red. Tried Magic Focus after 20 minutes and it was no better


you need to change the convergence chips that are attached to a heat sink, they are the two black chips with a lot of legs on them.
