Hi there. I have an awful problem going on. I have a Denon AVR-1400h and it seems like whenever the receiver heats up, screen starts turning to snow and then eventually goes black. This may end up being TLDR but this same thing happened to me randomly awhile back and I went from a 15m cable to a 10m and made sure it was a high quality certified one. Had no problems until about a month ago. Everything goes fine until the receiver seems to warm up 5 minutes in or so and then it starts happening until it become unwatchable. I have a nvidia shield and a set top box as the sources and it outputs to an LG projector. It doesn't seem to be the cable as when I plug it directly into the shield it works flawlessly. Doesn't seem to be the projector either in that scenario. No idea what is causing this. I've tried to turn off processing and the whole power control to no avail. Maybe the things just fried as I've already had it repaired once. Any ideas?
