Ive got a 9 year old Magnavox 31" tv that I am having problems turning on. When I hit the power button on the remote or button on the tv itself the tv will turn on but then immediately turn itself off. I can eventually get the tv to turn on and stay on if I try enough but sometimes it takes a few minutes. Does anybody have any idea what could be causing this problem?

Is the button stuck on the remote?


Try taking the batteries out of the remote & turning on the TV with the power button on the TV.

There could be a couple of reasons, but I would say that maybe the b+ voltage has exceeded it's regulation. This b+ voltage goes to the fly-back transformer and gets stepped up to about 30k volts. Because we don't want an xray machine, it is monitored. When you turn on your TV, it looks to see what the b+ voltage is. If it is too high, It will shut itself down.
