Question about Hitachi 43GX01B 43" Rear Projection Television
Hello don't know what my kids did but I have a bunch of red lines on the screen. Some of the lines form shadows so you see double of words that are on the screen. can anyone help
Projection sets have two very common problems outlined below.
The first common problem is convergence
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. The TV can also shut down when the convergence starts to fail.
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,Mitsubishi,Zenith, RCA and others.
You can more info and a DIY convergenece repair kit with instructions from TV Repair Kits using the link at the end of this article.
Here are some of the most common problems with these sets...
*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped or bowed
*No Audio/Video - TV Shuts down - May also make a constant chirping sound
Problem #2 - Another common problem is dull or washed out video.

*Dull looking picture
*White looking picture
*Halos around objects
