Hi Recently bought a Phillips TV model 55PFL5505. I have connected my HD Cable Receiver to the TV via an HDMI cable however, after at random periodic times, the audio feed gets very distorted/scratchy. It last for roughly 30seconds and then goes back to normal. I thought it was the HDMI cable so I tried a new cable but the issue still persists. I then tried swithing to a different HDMI input slot, however, this did not solve the problem.

Has anyone ever had this problem and if so is there a solution?

Thanks in advance for any help.
