Don't try that if you are talking about one of the three lens, very easy to open the wrong way and have the Glycol come out all over the place and it is toxic.
I know these sets well--just let me first know what the set is doing and not doing!
SOURCE: hitachi 51
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,Pioneer 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

SOURCE: 51"hitachi tv needs convergence module.What would it cost to fix.
Depending on whether your friend's diagnosis is right and whether that is the only problem, perhaps. Certainly if it is free you would have nothing invested beyond the convergence repair. Run it first and make sure that that is the only problem and other than misconvergence it looks good. I have a tip at http://www.fixya.com/support/r4220499-change_projection_tv_convergence_ics which explains the problem, how to repair it and where to get the parts. Let me know if you need more help.
Thanks for using FixYa and for the generous rating.
