Question about Hitachi 51F500 51" Rear Projection HDTV-Ready Television

1 Answer

Red will not focus with auto majic or manually

Hi, i have a Hitachi 51F500, the picture has a red shade to the right, was able to align the center part of the screen, however not the far right & left sides by using manual adjustment, it will not respond to the control. If you know what the problem is or if it can be fixed, please let me know. I've read about blue or green from others, but i'm not sure if i need the same part. Also, if there are parts that need to be replaced, is this something that i can do, or it has to be done by a service tech? THANK YOU!

Being that youre able to control adjustments in the center of the screen your ICs have to be good, you will need a tech for that repair as its a problem within the DCU , convergence yokes or faulty component within the convergence power supply other than the ICs.

Red Alignment problem on a Hitachi 51inch rear projection tv


The most likely cause is shorted convergence chips and possibly a few pico fuses.

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,Akai,Pioneer2_bing.gif Hitachi,Mitsubishi,Zenith and others.
You can get a convergenece repair kit with 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 - 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
