Had a wicked hour long cloud to ground storm yesterday putting strikes allover my 20 acre property. We did not lose power but lost cable/internet for about 5 minutes. My onkyo was turned off and is behind a good surge protector. We tired to use it today and no HDMI audio or video. On top of that, my cable box turns on just fine but no video when connected directly to the tv. The TV works, and hooking devices directly to the TV works. The Onkyo turns on and everything just no sound or picture. I can't even bring up the setup menu. Any suggestions where to start>?
