when i turn the tv on in the dark i can see all three bulbs light up normal for a second, then the green one starts getting brighter than the other two, then the two shut off and the green is very bright.(the screen turns all green as soon as the green bulb starts getting brighter than the others) then the green bulb kinda flickers(sounds like it shorts out) and the tv turns off. could it just be that the green bulb needs to be replaced? please help! thanks bill

it looks like something may be shorted or a resistor open on the green crt board. this set has 3 picture tubes, the green one is in the middle. if you know nothing about tv's on the inside then i would call a repair to look at it. also could be shorted crt itself.

Please check the Video +B (200V) for green is getting shorted. Remove the green CRT board, if the tv does not off and cathode voltage at green cathode does not die, then the green crt is shorted.
