Picture went out and all the tv does is make a buzzing sound
I was watching a football game Sunday afternoon and the picture went out on my TV. The sound was there, but no picture. Then after a minute of that, the sound was gone and a humming noise started. I unplugged the tv, then plugged it back in and the same humming noise. While plugged in, none of the buttons work on the remote control or the on the tv. You can't turn the humming off unless you unplug it. So, I waited 24 hours before I plugged it back in and still the same thing. Any recommendations?

The horizontal output transistor drives a transformer that gives you the high voltage to light up the picture tube,either the transistor or the transformer have gone bad,sometimes both have to be replaced and sometimes the transistor fails for no reason by itself.Be safe and call for help if you are not familiar with tv service.

if you have the right video inputs and your cable box is working then your tv is shot . sometimes your cablebox is outputing excess poxer that can affect your tv .also get your cable tv company involve.
If you lost the picture and even the menu does not show up on screen, then I will bet that your high voltage has shut down or the computer has stopped the picture because it has detected a fault in the vertical circuit. In either case this is something that cannot be reset with the buttons or remote and should be handled by a qualified tech.
