Hi all,
Having a little issue, which is making me concerned for my Marantz SR7002 AV receiver and/or Right speaker at the moment.
Every 2-3 hours or so (continuous use), I hear this quick loud low freq thud sound from my speaker (which to my ears is variable in volume, depending on my main volume on the AV receiver??)
Have heard it via computer (HDMI to TV, then Optical out to receiver) and also now via Sony TV (using internal apps) via optical out again.
Can optical do this?
Things to Try:
Turning portable heater off. Removing remote AC power plug on/off power (using behind tv, as cannot access power plug). Using Sony 4k bluray player Netflix app instead of Tv internal apps, which is connected to HDMI (audio) to AV receiver to isolate the optical connection from Tv.
Using Filtered or unfiltered power surge protection from THOR power board.
LAST resort - Leaving AV receiver on for 2 hours or so without any source as such and just listening!
Regards,
Ron
