Why is it that after the big change to High Def the other day your TV makes an electrical buzzing sound off and on all day I have cable and a friend has satellite with the same problem?

The buzzing sound from your TV after the switch to High Definition could be due to several factors, including interference from electrical devices, issues with the signal quality, or the TV's internal components reacting to the new HD signals. If both cable and satellite users are experiencing this issue, it may indicate a broader problem with the signal transmission in your area. Additionally, the buzzing could be a result of the TV's power supply or speakers struggling to process the new HD content. It’s advisable to check connections, move other electronic devices away, or consult with your service provider for further assistance.
