The colour has gone green and purple

I will start with a simple deduction that one primary colour has gone, the set has three Red, Green and Blue with this and our easily tricked eyesight we make other colours.
To me if this was a hulking glass tube type TV I would think one of its tube guns has stopped working this can be the chroma drive IC or more likely an out put which is mostly transistors mounted on the tube base gone bad or dry joints in this area. A tube can go but they mostly age and go off colour over time, I have also seen sets have power supply troubles which causes a low supply rail this results in some very strange events. A hoover started up in front of the screen can magnetise it as can a child with a strong magnet moving it around on the glass, a set will try to cure these last two each time its switched on (degauss) though the magnet one will be harder to cure! I am afraid it would need a service call to determine if its a joint or small part it may then be worth it, while a tube problem forget it. Also if this is a flatscreen then its possibly not worth it anyway, if its the screen+output IC set up, a screen is about 66-75% of a flatscreens build cost. On the other hand if its the main circuit board all an engineer can do is replace it with a new one (if around) because they are made in such a way with machines a man with a soldering iron stands No Chance. Hope this helps.....

My sanyo tv screen keeps disappearing with green lines on thris

Green retrace lines could me two things, the green gun in the CRT is shorting out and that is the picture tube, and it is not worth fixing. Another thing that it could be is a bad neck board and the green driver transistor is shorting, but that would be green all the time, I would say it is the picture tube, and buy a new TV.

Green picture only

The projection TV has 3 guns RED GREEN BLUE. In your case the red and the blue guns are gone. So you are getting the green color screen. You got to replace the picture tube.

Sanyo HT32744 Picture mostly green and blue

On mine I took the rear cabinet off, unseated the card mounted on the picture tube, applied a little dielectric grease on the connector on the card and reseated the card, removed, re-greased and reattached the card. I have had no problem with either my or mom's which I did the same to since! This is an easy fix that anyone can do. The hardest part is moving the TV and reassembling the rear cabinet. Do not pull the cabinet back out more than you have to, to ease the reassembly of it.

Green horizontal lines

Hi, I have a Philips 29PT9009/12 TV. Recently I have begun to see horizontal green lines on my tv, when either watching a dvd or watch tv. This has gotten worse and now the green lines are more visible and the background is now turned a shaded green. Please help me. Thanks in advance

Everything is green

It might not be anyone of the CRT's that is at fault. There are circuits that drive the CRT's that can cause the same issues as well. I would have a TV repairperson look at it to make sure.
