HTR-6080 A/V Receiver
For some reason, one of the HDMI (INPUT 1) inputs on my HTR-6080 is all of the sudden causing "Not Supported Mode" on my HDTV. It worked fine just a few days ago. If I plug the same component (BluRay) into HDMI INPUT 2, all is fine.
When I check the signal info with the BluRay player plugged into Input 1, the receiver will display the correct 1080P resolution BUT see it as a DVI component. If I change resolution on the BluRay to 720P, the receiver will display that the source is 720p. So it is getting the video feed but see it as a DVI signal
When I plug the same BluRay player into Input 2, the receiver detects it as an HDMI source.
Seems all HDMI components I plug into Input 1 are seen as DVI.
I've performed multiple Factory Resets and this did not help. Any ideas to solve this would be appreciated.
Since it is one input, there is a good chance the socket has become damaged. The HDMI connector is a very bad design, fragile and easily damaged.
You should plug and unplug into these sockets as infrequently as you possibly can.
It is possible your HDMI board is starting to fail. Either way these boards are not serviceable and the HDMI board will need replacing as the sockets are mounted to the board.
I see that receiver is 2001 vintage, so now 11 years old. This is getting to the end of expected life span for equipment of that type.
I think I would consider replacement over repair, unless you can do it yourself. If you are handy, try and buy a for parts or repair machine on eBay, that has a different problem and swap the HDMI boards. At that age there is a very good chance a new board is NLA.
However a lot has changed in 11 years and I would think replacement is in order.
