When TV is on, the green color sometimes isnt being projected or very lightly as there is a heavy red tint. stuff that is supposed to be normally green is very dull or gray colored.
Occasionally i will see a light green flash cover the whole screen and the picture will be normal again.
It is intermittent and goes from normal to green not working frequently. Lots of light green flashing.
Had the convergence board replaced last year. When green is out, perfect focus does not work and unable to do any green convergence from the menu.

It sounds like the common problem with this set. It is an intermittant picture tube, or there is a loose connection on the green drive board on the green picture tube. Try lightly tapping all around on the green drive board while the set is on and see if you have any change. BUT BE VERY CAREFUL! Lots of high voltage on the board. Also use a plastic or wooden device to do the tapping. If you do great, you know you need to resolder the connections on the board or clean the CRT socket on the green drive board. If there is no change, I would bet the green CRT is on its way out. But try tapping the green drive board all over as I said before, that is a very very common fault with these types of TV sets. Good Luck
It sounds like you can have optical engine issue. That's if green tint was show up very gradually, until one day it really caught your attention.Normally some parts of the screen more green than other. It should get progressively worse. To solve this issue optical engine have to be replaced. It is pretty expensive repair if your TV is out of the warranty. In case if tint appeared suddenly in one moment - you can try to check component cable connection on the back of your TV if you are using one ( green, blue and red colored). Sometimes it's loose or after disconnection people reconnecting it in wrong way. Experienced tech will determine if optical engine is bad by running test patterns in special service mode. If green tint present on Grey scale - optical engine is bad. Sorry for bad news. Regards. Russ.
Hi Thanks for using FixYa. Usually
this happens when the Light Engine has gone bad, and I should say this is a
common issue with Projection TVs. There are three tubes/mini LCDs inside your
TV- green/yellow, blue and red. When the set heats up over time of usage the
screens tend to break resulting in leaking color everywhere. The cost to get
this fixed by a professional should be around $300 depending on the parts that
needs to be replaced. Please do accept the
solution if the issue is resolved or else revert for further assistance. Thanks Rylee
inside the light engine there is a red a green and a blue glass color filter.The heat from the lamp causes the color to burn off the glass.You need new filters .One is red one is blue and one is green.The lcd itself doesnt make the color,it is a black and white device.The colr comes from light shining through colored glass

if you have hd cable or satellite box make sure the component cables are properly connected(green red and blue) and matching same color in source (cable box or satellite and tv as well)
also make sure in tv menu that color and tint are 50%
This tint of green may just be one of the chips going out(There are three chips: red, green, and blue.). You can buy these for about $80-$100, but sometimes they are hard to come by(depends on where you are). You may also try to readjust the screen from the back. If you look in the back if you remov the wood that covers the back of your TV, there should be about 6 little knobs you are able to turn(Focus, red, green, blue, tilt, or reset...i think).try that...
It also depends on however long you have had this TV. It this time: you may also want to buy new resistors, for some of them may just blow out right after you fix the chip.(they are about 50 cents-1 dollar).
