QIp7100 - noises

I have a high pitched noise emanating from the power supply area of the unit.   Software resets have no effect on the unit.
The noise returns when the STB is reset.
Unit installed NOV 2011
no other issues
noise started with in the last week
I have powered it down, did a software reset and issue returns after the STB posts.


7100's should be virtually silent.  Time to contact Verizon.
