Ok a few possibilities here.
1. Heat; are the products in a well vented location with nothing right on top?
2. ESD; Any surges or spikes? These usually come from a device with a Coax/Ethernet cable connection.
3. Overall poor 110 Volt grounding.
If you have seen multiple failures it is most likely one of the above and will continue until the actual cause is identified and corrected.
Those are all great possibilities, and worth examining on each job. BUT the offending TX-NR series receivers I have installed all seem to have the same exact issue.
Lets say it is poor power grounding... on so many jobs? I usually follow behind the cable company and check for proper ground. I place the network equipment on battery back up and or surge depending on the rack.
If it were a power tolerance issue, would that be because of cheaply protected circuits in the HDMI circuitry?
I have since moved on to Maraantz and really like their product much better. If there are issues I will only use Zektor switches instead of a receiver altogether.-- It is possible to designate their audio outputs as L/C/R RR/LR.
