I have two sources for my PNF8500: Apple TV and a BluRay player. Both connected via HDMI cables to a Denon receiver. The Denon receiver is connected to the TV via HDMI.
Almost daily, the picture will become snowy, pink, or pink and snowy. Sometimes it will warn me by starting off with minor snow and then go full snow and/or pink. Other times, there is no warning. Everything will be fine, then suddenly there will flash a momentary black screen before it turns to snow and/or pink.
Whenever and however it happens, I can still see the picture through the snow and/or pink and the sound is never impacted.
I can fix it by unplugging/plugging in the relevant HDMI, sometimes one unplug/plug will do the trick, sometimes many repeated unplug/plugs are needed.
Whenever it happens, changing sources doesn't help, i.e., switching on the Denon from Apple TV to BluRay or vice versa doesn't make it go away.
The receiver is relatively new and in fact we bought the new receiver specifically because the same problem was happening with our prior receiver, an Onkyo. I had read so much about Onkyo problems that fit this description, I figured it must be that, because the TV then was brand new and the Onkyo was nearly 7 years old. So changing receivers didn't work.
I have also tried switching out the Apple Tv for a second Apple TV we use in the basement. No luck. And in the basement, we didn't have an issue when we tried the upstairs Apple TV through the Vizio TV we keep in the basement.
The TV is from Oct 2014, so past warranty I think. Talked to Samsung, and so far their thought is that the Denon "isn't sending the right signal to the TV". That I should instead run the sources directly to the TV then kick the audio back to the Denon. I don't want to do this and also it doesn't seem like that could be the problem. Samsung wants me to run the Apple TV or BluRay direct to the Samsung to see if the problem persists.
I will try that but in the meantime, any thoughts?!? I am losing it!!
