YK Thom Posted June 9, 2019 Share Posted June 9, 2019 Last night I lost video through the Marantz 5008. Audio only. Have had issues with the cable box and replaced it today. Same story. Audio no video. Cable box HDMI to Marantz CBL/sat. The unit was working fine with the Apple TV so the TV hasn’t died. Swapped out the cable to receiver HDMI with brand new one. Same issue any help or suggestions would be appreciated this is really not doing my Saturday night any good. 1 Quote Link to comment Share on other sites More sharing options...
MC39693 Posted June 9, 2019 Share Posted June 9, 2019 Some folks here and CAM have noted over heating as source of fried HDMI boards on various AVR. Quote Link to comment Share on other sites More sharing options...

YK Thom Posted June 9, 2019 Author Share Posted June 9, 2019 Let me see if I understand. Run RCA from cable to AVR. RCA from AVR to TV? Quote Link to comment Share on other sites More sharing options...
billybob Posted June 9, 2019 Share Posted June 9, 2019 That should work... video audio out to AVR in... out video audio into tv... Quote Link to comment Share on other sites More sharing options...
billybob Posted June 9, 2019 Share Posted June 9, 2019 Make sure of your outs to inputs with the jacks... the idea is to bypass the HDMI until such time as allow s trouble shooting.. Quote Link to comment Share on other sites More sharing options...

YK Thom Posted June 9, 2019 Author Share Posted June 9, 2019 Alright, I have some RCA cables in the spare room. Will give this a go in the morning. For the time being, Netflix through the Apple TV is keeping the wife calm and happy. 1 Quote Link to comment Share on other sites More sharing options...

billybob Posted June 9, 2019 Share Posted June 9, 2019 As another after thought, when the AVR is cool, you could consider testing the HDMI output to telly again just to let you know what may be happening from that particular out put, if not done so already... this before using the composite or component out put to the set... cheers.

YK Thom Posted June 9, 2019 Author Share Posted June 9, 2019 The plot thickens. Turned on the system this morning. Was going to listen to internet radio through the Apple TV. For a lark I tried turning on the new cable box again ( to see if the stove was still hot I suppose); it comes on video et al. Overnight firmware update for the box? Fluke ? Can HDMI ports function intermittently? For now Cindy is happily watching her Sunday morning Coronation Street episodes. Strange. Quote Link to comment Share on other sites More sharing options...
Bosco-d-gama Posted June 9, 2019 Share Posted June 9, 2019 I own 2 Marantz avr’s, an older unit and a newer unit. The older unit was pre-hdmi. I have had no problems with either device..... and.......yes......there are a number of ways to connect various signals to each device. Each will accept rca and optical signals. HDMI connections are convenient but not exclusive on my units. Quote Link to comment Share on other sites More sharing options...
YK Thom Posted June 9, 2019 Author Share Posted June 9, 2019 The only things that have changed are an HDMI cable swap and the Motorola cable box itself. I will shut it down later and try it again after she is done with her shows just in case it was a fluke. Perhaps there was some issue establishing the initial handshake. 1 Quote Link to comment Share on other sites More sharing options...
