Since my uverse high speed internet and video system was installed I have a persistent low decibel humming/vibration noise throughout the house. Thought originally this was outside my house due to a heat pump or generator, but cannot find a source. Do you have others who have this problem? Is this the cause, and if so what is the solution?

Previously Tech Support here of ATT Uverse. For your issue you may want to try this steps by changing the input: click number 7(same as input) on your att remote you should have input lists on your tv screen. If not doing anything use your TV remote and find there input,source or tv/video and you should have input lists on your tv screen. For the input you should choose HDMI 1 or 2 if you are using HDMI cable. If not try to choose anything on the input lists and you should get the right input in order for you to watch on your DVD and going back to TV. Hope it helps
It's called a pillar box and it's normal when watching standard definition content on a high definition television. You can adjust this setting by pressing the format or pic size button on your original television remote or by pressing the zoom (bottom right corner) on your Uverse remote.
plse dont move when there are working, inside them are components which gets heat, vibration causes separation or desoldering them from board.(dry joints)
it may be coming from cables having dry joints take your set for repair.
