Green CRT doesn't come on

I couldn't get the color correct so I took the front off the tv and can see that the Green CRT doesn't look like it's on at all. Does this mean it's the CRT or is there somewhere else to look? I have adjusted the screen knob to no avail. The TV shop has told me they would have to replace all 3 crt's and it would be over 1K to fix. Help! Thanks!

My sony kp-51ws500 tv screen would turn green and stay on for about 30 sec, then trun off. I adjusted the green screen button on the black box in the front of the tv....via info from this site. It fix the...

Doing the adjustment is not actually a fix, all that does is change the drive amount of the green CRT which allows the set to work but the 3 CRts will be out of balance so picture color will be affected. The only way to repair a bad CRT is to replace the CRT itself. You can get replacement Green CRT from

Projection tv 42" panosonic hdtv. to much green in the picture. Jeff

this unit may have a resistor on the green crt-board that has increased in value. check ohms(resistance) on all crt boards and compare to one another. these will have color bands that inicate value of resistance. you do not need to know color code, just match colors of resistors on each board then measure. you could also have weak green tube. turning down the master screen control located on the fous/screen block can reduce grn. drive. to adjust proper drive for each so the grey scale is correct, turn color to tv all the way down then adjust screen controls on block for black & white picture. when color is turned all the way down, you should not have any green, red, or blue over cast on screen. mch

I think problem is in Protection circuit itself. Protection seems unstable in your tv that's why it doesn't give you chance to diagnose problem.
Try to isolate protection command and check tv.
Its an idea and hopefully it will work.

I had the same problem which was caused by a bad solder connection on my Green CRT driver board. The fix isn't too difficult if you've had some soldering experience.

1) Determine which CRT is going out (Reg, Green, or Blue). Looking at your convergence adjustment screen will help.
2) Unplug TV
3) Remove the front panel
4) Locate the driver board attached to bottom of the bad CRT.
5) Locate the two large heatsinks on the driver board, each has a transistor attached to it.
6) Touch-up the three solder connections on each transistor. Adding some new solder helps.

in the front cover turn up screens on all colors till you see retrace lines, then back them down to where dissappear. enless you know the correct voltage to set it. as for the green. i would try the red crt on the green and see if it looks ok. if so then replace crt circuit or check transistors on crt circuit may also need to change the driver on the heat sync.

Adjusting the color convergence

You are going to have to have the convergence IC's replaced, the only way to correct this I'm afraid. Good Luck
