I just got new HD cable boxes. The main HD box makes a very loud fan noise--don't know if its a fan or a hard-drive. I've been back to the Comcast store three times, have tried 3 different boxes. I've also called Comcast and talked to them on phone--they don't seem to know why the noise. At the Comcast store we plugged in the box I brought back and it didn't make a noise. I've tried using a new surge protector, plugging into other outlets, tried plugging in w/no other tech near. I've never had any electrical issues at my house and have other/more sensitive technology equipment--never a problem. Does anyone have an idea why this might be happening? There must be some very sensitive sensor? in this equipment? Has anyone heard of this problem? Remedy? Thx!
