I'm having an issue with one of my components and for the life of me I cannot figure out whats causing it. I suspect something is "going bad" but I don't know if its the TV, Receiver, cables or something else. This is the equipment i've had set up for the past 3+ years:
- Yamaha RX-V779 Receiver
- Samsung UN65KS8000 65" TV
- Verizon FiOS One Cable Box
- Apple TV 4K
The TV is wall mounted, my front and center speaker are in-wall, and my mid/rear speakers are in the ceiling. I had a renovation done 3 years ago and we ran all of the wiring then. I ran a 25' HDMI (4K/18GB compatible) to the office which is behind my family room. In the closet of the Office I have a media cabinet which is where the receiver is located. So its HDMI from the TV to the receiver (HDMI1) and then the Cable box and Apple TV are connected via HDMI I have it set up so that the FiOS Remote powers on the receiver, the cable box and TV. If I want to watch the Apple TV I can use the Yamaha remote to switch to HDMI2 and then the Apple TV remote to navigate. Its all pretty simple and straightforward
So, heres the issue I've been having for the past 2-3 weeks. When I power on the system (Receiver, TV, Cable Box), I will get audio right away, but on the TV I get a message stating no HDMI input is found. It takes anywhere from 1-2 minutes for the picture to actually show up. So the screen is actually on because I get that message, but just no picture. If I switch to the Apple TV, it'll be the same thing - its at least a minute before it switches. If I switch back to TV, same thing - instant audio, but delayed video.
That led me to think the receiver was having an issue switching sources. I went and picked up a new receiver, connected it and the first time I powered it on I ran into the same exact problem. I ended up returning that receiver since that wasn't the problem.
So in the office I have a very inexpensive Westinghouse 40" 1080P TV. What I did was took the HDMI cable that would typically run to the Samsung TV and ran it to the Westinghouse. I powered it on and everything came up normally. Audio and video were instantly on. I started thinking that maybe it was the cables, so I replaced everything (except the 25' because thats run through the ceiling and I can't get to it. Same Issue. Theres a few other things I've tried.
Direct from cable box to tv (bypassing the receiver entirely) and I the same delay.
Plugging the Apple TV into the TV HDMI2 (leaving the receiver/Cable as HDMI1) - Audio delay with the Cable box, but Apple TV, No delay.
Plugged the receiver into HDMI2 on the the TV, and got the same delay.
It seems like a cycle.. Whenever I narrow it down to something, its not that. I'm 99.999% sure its not the receiver because the same exact thing happened with a totally different receiver.. even a different brand (Sony), and it has happened when I've taken the receiver out of the equation. I've replaced all of the cables (except one) and I dont think its that one because when I ran the AppleTV direct I used that cable and not only was there no delays, it actually ran at a higher quality (4K HDR.. when I go through the receiver it only does 4K SDR). It seems like its the TV, although I dont know that its a bad port because it occurs on HDMI1 and 2, but only when its the receiver/cable box connected. Its almost as if the TV cant handle everything being connected. I did a full reset of the TV (as per Samsungs instructions) but still the same thing. Its not under warranty since I've had it 3 years, but its quite a hassle to go buy a 65" TV to test it out only to find out thats not the issue either. ( Even though it worked on the Westinghouse, its only 1080P and I'm wondering if its just so basic its not using all of the functionality.
Is there any other tests I could try to either pinpoint it to the TV or eliminate that from being the problem? I'm totally stumped.
