When I turn it on there is a strange whining sound and no picture. Anyone had an experience with this?

Thanks,

Is the sun shining where you are? Knowing the weather is as about as helpful as the information that you posted.

Start with model number. Absent that, whats the technology? CRT, Plasma, or LCD/LED?

Whining complaints along with a change of performance are *usually* a switch mode supply under a higher than designed for load.
