Dlp tv color goes fuzzy and green


Its probably unrelated to lamp, take the lamp out, try it again and look into the lens, if its still very green the projectors electronics are failing. The projector generates pictures as 3 streams of info Red Green and Blue. It looks like the projectors red and blue electronics are failing, but the green is working.

Picture was fine, then lines diagonally, now light


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.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

No picture coming from red lamp


Sounds like you have two differant problems. A red drive or red picture tube is bad and the conbvergence IC's are bad. To test the red drive disconnect the green picture tube socket BUT MAKE SURE THE SET IS UNPLUGGED!!Then remove the red socket and move over to the green tube. Then turn on the set. If you get the same out of the green then you have a drive problem that needs to be trouble shot for a bad componet. If you do get a picture with the red connected to the green then the red tube is shot. If you know how to read a schematic, get one and then you should have no problem troubleshooting the red drive and the convergence problem. If you dont then there is no easy or quick fix as this is a solid state set and there are no user replaceable parts inside this.,. Your going to need, for safetys sake, call in a trained tech to assist you with this repair
