So I've got a Denon X6700 receiver hooked up to a Samsung 65" TV on the main output and an Optoma UHD60 4K projector on the sub out, been running for about 6 months with no issues at all. The amp is only 6 months old, but the projector is 2.5 years old now. I've never had any issues with the projector at all, but a few weeks ago I noticed when using HEOS to turn on the amp, no music would output and there would be no speaker symbols on the display, I'd have to reboot the amp every time to get it to work. If the amp was switched on first and I then opened the HEOS app it worked perfectly, it was only when trying to initiate everything with the app that it didn't work. Maybe unrelated, but thought it was worth mentioning just in case!
Then last weekend I turned the amp on to watch TV, and there was no sound. No speaker symbols on the display either, but this had never happened before other than with the HEOS issue. I then turned on the TV and saw there was no picture either, and a quick Google search said that these symptoms could well be from a faulty HDMI board in the receiver. However, where this gets more intriguing is that after swapping back to my old receiver so I could still watch TV, I turned on the projector and that didn't work either, just saying "No signal".... So I did some investigation, tried hooking up a Google Chromecast directly to the projector and still nothing, but when trying the other HDMI input on there I was able to get a picture from both sources, so essentially HDMI 2 was broken.
As part of my investigations though, I also tried another HDMI cable from the receiver to projector and this one worked using HDMI 1 input, when my other fibre optic cable didn't work, so this was ALSO broken! Just to confirm, I also checked the fibre cable between Sky Q and the receiver, and it's definitely broken, so what on earth could have caused this?
It's too much of a coincidence for the receiver, cable and projector to all break on the same day unless it was related, but I really don't know what can be to blame for this. As it's a fibre cable too, surely there's no direct electrical connection between the receiver and projector that perhaps a spike could have fried all 3? If you had any input on this I'd love to hear it!
