The Constant Humming Noise you hear is coming probably from a transformer on the inverter board.There is no immediate danger -but this inverter board might fail in the future.The symptom will be no back light anymore.It will still have picture but very dim.
Sometimes, it a Symptom of a Loose Solder Connection on the Power Supply Board as well ( In Rare Case ).
Do one Quick Check.Disconnect the Cable Box and Run a DVD Player. If you still hear Humming Noise while playing DVD player, you need to Call professional who would Inspect, Test and Replace Board or Inverter.
Inverter is Different than Power Supply Board. This has to be Diagnosed properly by a Repairman.
If you do not hear any Humming noise while playing DVD, then we need to troubleshoot the Cable Connection.
Let me know, if needed further assistance.
Hope i helped you.

I guess, it would be between $125 - $175, depending on which Component is at Fault.
