Try not to do repair yourself. the tv holds high voltage even when unplugged. you could KILL yourself. If red is fading the convergence ic will not help. you need to replace all the guns. red, blue, and green. usually each tube or gun is around 300 dollars each.

Shadows and double vision


Projection sets have two very common problems.

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. 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

Red color on screen is warped on my LCD projector TV.


Normally the oily fluid coming from a picture tube, is the coolant from the tube. It's very combustible and have been known to start a fire. You have two problems in this set. A leaking blue picture tube. A convergence circuit that needs repaired. Call a local servicer and see if they will give you an estimate over the phone. It's time to start looking for a new digital set. Good Luck.
