Do I have a Faulty AC ADAPTER? [TV]?

The AC ADAPTER for my TV might be faulty
I had unplugged the TV for two weeks straight at the time that it was working
and recently decided to plug it back in again,

.The red standby light came up
.I pressed the power on button
.I waited for ages...and nothing was on screen
.I began to investigate the problem
.I put my head close against the TV speakers and i could hear a faint fuzzing sound
.So i turned it off and back on again and still nothing
.Then i unplugged it and listened to the sound of the AC ADAPTER and i could hear a low pitch buzzing sound.
So it may seem that because i didn't use the TV for so long something my have been damaged

Or could it be that the AC ADAPTER isn't supplying enough power for the TV, because the TV still goes on standby but will not turn on properly.

Can anyone help me?
