The green tube is dead.

the color tv display used mixing of three colors, (red, green and blue). it lost one color, coomon problems: lose contact of base of picture tube or its wiring, sockets, capacitor dead in rgb section, dead video ic

DLP tvs have a design weakness,the problems it is call a convergence problems,it is dead.This convergence problems,will have happen many times through out the tv live.The tv have a colors R,G,B lines misalignments,have colors shadow pictures or 3D pictures look alike?Yes,than the tv board,that call the tv convergence board it is dead.The tv convergence board,must require changes 2 STK convergence ICS and some or all of it resistors too.To fixed the tv convergence board to solved the tv colors picture convergencce problems.The tvs shops will cost u like $300-350 for parts and labors.

All projection TV sets have two very common problems. One is convergence ( 3D/Warped video or dead set) the other is CRT fluid ( Dull Video). Here are more details and solutions for both.

Common Problem #1) Convergence has gone out

Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. In some cases the TV will also not show any video. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

Common Symptoms include....

• Screen looks 3D
• Colors don't line up
• One or more colors can't be adjusted when using the convergence menu.
• Screen is bowed or warped.
• TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.

Here are some pics of convergence problems.






Common Problem #2) CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

Tv have convergence problems,it dead.Colors lines R,G,B don't aligned.The tv convergence board is dead.The 2 STK convergence ICS and some or all it resistors are dead,these parts must be replaced to solved the tv pictures covergence problems.The shop,will cost u $300-350 for parts and labors.

This is a picture tube type TV. No lamp.
You don't describe the distortion.
A colour green picture that is twisted and shifted away from the other colours is a convergence problem. see Projection TV Convergence on this site.
If the green is smeared, out of focus, larger than the other colours like a halo around objects, things like that, it is the green picture tube. Sony has discontinued most of the picture tubes so you may not be able to get this fixed.

For a rear projection set there are three tubes that work in unison that provide the color image. The tubes must all be working properly. The fact that it happened all of a sudden is usually how televisions fail.

The possibilities are losing the red drive, losing scan to the green tube. If the line is very bright don't operate the set because it can actually damage the phosphorus inside tube if it stops scanning one tube. That is clearly a internal defect and you will require a competent in home service technician. Ask the manufacturer for a referral in your area. If there aren't any try a local shop, they will charge you for a diagnosis but that will be the first required step. The tubes themselves rarely fail but the electronics that drive them can and sometimes will.

there's a slight possibility it might be your video board, i recommend disocuntdashmerchantdotcom for free troubleshooting :)

Hard to tell, but my first guess is that the green or blue video amp, or guns on the picture tube have failed.

My dad has a sony rear projection tv and had this same problem. A shop had to replace one of the color tubes(?) (green, red, or blue) had to be replaced. The shop said this was common with Sony rear projection TV's.
