Check the CRT base card to green CRT for any loose solder terminals. Re-solder all the suspected solder terminals by applying a little more solder to each terminals. Check the solder terminals of the CRT base connection socket too. The fault is with some loose solder terminal itself at the green video output stage circuit. Gopakumar Gopalan Google

Why do i have a green screen after i turn the screen adjustment screw?


since every display color monitors are only work with 3 primary color which are red, blue and yellow. You could also search it that by mixing these colors, you could get any color your want. Thats how color monitors work. Now in case of green color, it creates by mixing blue and yellow. When you are turning the screen adjustment screw, the red color plug will become lose, makes it appear green.
I hope your got the reason.

Clear but only blue/green color


Do you have a component cable hooked up to the TV? (cable with RCA connections Green/Blue/Red/White/Red)

If so you want to check that the red cable is tightly connected to both ends (TV and whatever it is connected to).

Good Luck...

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.

Green & red tint


Most likely nothing you can do to fix this. CRT TVs use 3 colors to make an image on the screen (Red, Green, and Blue). If you're only seeing red and green then chances are the blue has stopped working. You can replace certain parts in the TV but for a 27" TV you'll probably end up paying more for the repair than a new TV.

I don't recommend taking the cover off and trying to fix TV yourself without training. CRTs have a lot of electricity stored in them (even after turned off) and you could accidentally electrocute yourself.

After a few minutes the color goes to intense red and green


My tv didn't turn green, but the red separated significantly. It started off happening after a few minutes of being on (I suppose the defective part was "warming up"), then it got to where it was like that immediately upon turning the tv on. In my case, I had to pay a tv repair man $350 for a new part. There are 2 microcircuits that control the color alignment--one that controls the red only, and the other controlls the other 2 colors, blue and green I believe. Maybe your part is the blue/green controller, mine was red. The repair man said these parts fail so rarely they don't stock the part. The cost of repair may be different for a different part, but either way you have to choose if it's worth that cost to you. If you get rid of it, I'll buy your tv stand ;-), I bought mine from a friend and didn't get the stand in the deal.

Screen Green Tint


Turn down your color and see if the screen has a normal black & white screen. If it doesn't then the CRT is bad (picture tube). If it is black & White then you have a either lost your red or blue.That problem will be in your video driver circuit of which a service center can handle.

Bad color .


Turn the set on without an antenna, so there is only snow on the screen. Measure the 3 cathode voltages at the CRT, red green and blue. If the 3 voltages are about the same, around 175 volts, then the CRT is bad (purple picture means bad green gun). If the red and blue are around 175 and the green is over 200 volts, then there is a chassis problem, usually the video output transistor itself has gone bad or come loose.
