Have you tried another outlet? Thinking maybe there is a surge. However, I would contacting the dealer too to cover all bases. I had a Cambridge Azur 650r that would have codec pops and would also show snow on the TV and loud static white noise. Sent it in and got the f/w updared. Most of the pops went away but the picture would still go out but this time with no white noise and it would randomly turn off for no reason. I replaced with an MRX 700 and have had none of those issues although I have had a few different issues that were random.
