I was changing channels and the picture just slowly turned black ending with a white vertical line before complete going out. I tried to turn it back on and the tv won't come on, as if there was no power going to the tv. I tried plugging the tv into another outlet and I still could not turn on the tv. Is there some sort of reset button on the unit or has the tube gone bad? Please help. Thank you.
You does not mean about picture clarity before this problem occurs. Former the picture clarity is well and good means picture is not problem. There is a problem in horizontal deflection area.May be flyback transformer failure shows these type of problem. This service should be done by technical persons only.

It is possible that you have a shorted green CRT, you can remove the front speaker cover, and you will fine a focus block, and if you turn down the green screen voltage, very slowly, the green should turn down. if not then the gun (CRT) will have to be replace, If it does turn down, then go into the menu and turn the color are the way down and that should give you a black and white picture. If it is not black and white. adjust the red, blue, and green screen voltages until you receive a good black and white picture. Turn slowly they are touchy, and if turn to high, you will get retrace lines and the TV will shut down.
Do you have audio and if so can you change channels to hear other programs? If so ...you have a bad vertical IC. Have a tech turn up the screen control to see a white horizontal line. By your question I would say this will correct the problem.
Hi, According to the symptoms, There is a problem in vertical out section.Just check it there must be a capacitor that has been burst or leak.And second one reason could be the malfunctioning of vertical IC.Which is also in the vertical section.
whenever you see horizontal line please reduce brightness of your tv for safety of crt.
your problem in vertical section only mostly due to loose contact in
connector,print or loose components.
You can turn up Screen control in back of set on the High Voltage Transformer and see if you see anything like a thin white line going across screen. If this is happening then it's your vertical IC output gone. It will have to be changed and a 100uf@50v cap in the same area.
