I have a 2006 Sony KDF-55-E2000, just replaced the lamp and housing and now I have a green stripe at the top and a red stripe at the bottom. Is it worth having this set repaired if I do not have an ex


We had the same problem. Let it be and now the tv won't turn on. If I understand correctly from what I've read it's the optical block and they seem to be just as much as a new tv.

Green and purple band of color


Projection TV sets have two very common problems listed below.

Problem #1) 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. 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 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...

*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

Sony 46" RPT color problems


Hello BlueKalel,

It looks like your green CRT is malfunctioning. You should try to see if the voltages are correct on the socket of the green CRT and check the high voltage on the green CRT using a high voltage probe. Use a schematic diagram to reference these voltages to.

I am positive that the problem is the green CRT or the circuitry leading to the green CRT. Please use caution when checking these voltages.

Thank you,
Shuttle83
