Hi guys. So I seem to be having a very odd issue here. I recently bought a Marantz SR5010 which had previously been used, only for a short time as a tester in a magazine here in Norway and then just a demo model for the importer. So basically not used at all. I hooked it up an all is good. I'm playing around with settings and I notice the upscaling for 4k is own. I figure most of my source material is 1080p and I won't be using 4k at all, so why not shut it off. And so I do. Later I decide I'm gonna watch San Andreas on my projector and screen, big movie big screen right. So I notice pretty quickly that the projector isn't displaying any picture no matter the settings.. Back and forth and nothing.. So I figure make sure the upscaling is of, apparently I hadn't so I turn it off completely. Picture flickers a bit, I figure no problem.. Disconnect hdmi to the projector and maybe things will take care of itself, in case they were messing with the auto settings, considering the TV is 4k and the projector only is 1080p. Great. So I'm standing right next to my LG TV and I start noticing that there's an awful lot of snow/grains in the image. Start playing with the image settings in different places, trying to find a solution to the problem somewhere.. To no avail. Except when I turn the upscaling back on an leave it to auto (4k) it works fine, but still no projector image.. A little less worried just figured it was being moody, so I leave it as such for a few days.. Come back from work one day and I have a basically only green colors. Nobody has touched a setting and its playing with me.. I change up the hdmi cables, try connecting the ps4 directly to the TV and the pictures is as perfect as can be.. So I figure faulty modell even tho nobody saw it during testing, apparently.. So I order a new in box SR5011, open it up, connect it up and power everything up. Nothing. Try pressing a few buttons different settings.. Nothing. Press the setup button and enter the basic setup I have picture, for two seconds. It goes black.. I piss off.. Go to bed.. Try a bit more the next day, still nothing.. A few days later I've delivered it to the workshop they say it's faulty and I get a new one. Hook it up, no picture for maybe 5 minutes. Enter the basic setup again, voila image. Everything is perfect. Bliss. Tonight I go to watch a movie and it starts flickering a few minutes in.. And keeps randomly flickering on the left side of the picture.. I'm starting to think there has to be something wrong with my old equipment.. Which is An LG 65UF772H PS4 XBOX ONE XBOX 360 MARANTZ SR5011 and a different assortment of cables Everything worked fine before I replaced Mye onkyo with the Marantz. For the most part Belkin cables, one Sandstrøm (Dixons group cable, Norwegian brand) and the original Xbox cables. The Xbox one gave me perfect picture the two minutes I had it on one the sr5011, somewhat grainy on the sr5010 but got better when I had 4k upscaling on also. My question is.. Faulty cables or? Rationally it seems so.. I just don't get it when the onkyo txnr616 work flawlessly with the same cables.. Only reason I exchanged was for the different less harsh sound on the Marantz.. I'm starting to regret it now.. Any suggestions/answers are greatly appreciated.
