The sound is coming from the speakers not from the unit itself. It sometimes sounds like a crackling sound and is accompanied by a quick bright flash on the tv screen. Could it be related to HDMI polling or interference? It does NOT occur during blu-ray playback--only with wireless streaming.
I have the bd-p 3600 firmware 2.05 (problem also occurred with 2.04)--when watching netflix movies, I periodically hear a clicking sound and sometimes see a screen flash for a brief second--the sound occurs even when the player is on but does not occur when watching a blu-ray disc--I have the multichannel sound outputs hooked up but the problem occurred also with the optical digital output too. Video is via HDMI to a Mitsubishi DLP set and video is set to 1080p and 24 frames per second (tv is capable of this). Any idea what this is? It is annoying when watching a film on Netflix to hear the clicking every few minutes. Thanks.
