Question about Televison & Video
Initially, it would be suggested to try viewing a DVD or a VCR and determine if the humming sound & no color persists. If yes then conclusively, there is something wrong with the TV. If none, then the source of the humming sound would be the tuner section (internal to the TV) or your cable TV/aerial or your cable box/decoder.
If the humming sound and no color is present in either TV tuner/channel and with an external video source such as a DVD, then chances are that a large filter capacitor inside the TV needs to be replaced. It would probably be in the power supply section AC side.
If the humming sound and no color is present only on TV tuner/channel, you would have to check your TV signal source. If you are using an aerial, it may require re-orientation; if it were a basic cable, then you would need to consult with your cable provider; if you are using a cable box/decoder, then the problem could either be with the box/decoder or again your cable provider.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
Good luck and kind regards.
