| Well i have been using the tv without the green crt board plugged in so it is working fine but the whole picture has a magenta (pink) hue to it.
with the green tube plugged in the other two tubes shut down making the green completly overpower everything. ??? |

| if you are refering to the small dial on the crt board, then yes.
i also adjusted the focus control located on the board that is located on the right wall of the tv. had no luck with those either any other ideas? your help is greatly appreciated. |

| okay heres where i am at...
I have removed the green crt board and resoldered all solder connections. Reconnected and same problem by chance i removed the green crt board with the tv on and when i did the blue and red bulbs came on and work perfectly (no smearing of picture) needless to say i can watch tv but the whole picture has a magenta hue to it. Seems to me that the issue is in the green crt somewhere and is related to that tube getting too much voltage and forcing the other two to shut down. Someone should let me know if im on the right track here. Thanks Again |

| Just to follow up with some more information...
i have found that when i change inputs to ext-2 i do get all three tubes to come on when you get to the code entry screen (because that input is locked with a code you have to enter) however the normally green lettering (against a blue background) for that code entry screen is washed across the screen almost smeared looking. As i am sitting here typing the TV just shut off on its own. after being on that ext-2 screen for approx 5 minutes. I have also checked to make sure that the green tubes coolant has not leaked on to the crt board. as of yet i have found no cold solder joints on any of the three boards (but i just started looking with the green one) Thanks again in advance... |
