Hi my tv wont turn on. No picture. Just a sound like a buzz. just a black screen.


Hi,
Model number and brand of tv will help us to understand what kind of tv you have and what could be possible reason of problem for buzz sound when you turn it On.
Without tv model number and brand info, it is not possible to suggest any thing because many kinds of tvs are being used.
Thanks.

Sound no picture


those are the screen adjustment controls, most likely they are turned down to low so the tubes wont power up. What happens is when you adjust them the set will continue to operate then when its turned off say overnight the tubes wont come on cause they are set to low, Try turning each of the 3 dials up just a little at a time equally untill the tubes turn on.
