Genie hdmi port keeps failing during storms
I have 3 directv receivers in my home. I have one connected to a Roku brand TV. I have had to replace the receiver in that one location 3 times now after three electrical storms. The receiver comes on but the hdmi output is bad. I have the receiver in a belken surge suppressor. the tv is also connected to a surge suppressor. No other electronics in the same pair of suppressors are damaged after the storms. I can’t figure out what keeps damaging the receivers in this one location. Any help would be greatly appreciated!!!

You have a grounding problem either in the TV or one of the power receptacles Probably a power surge is travelling down the HDMI cable to the HDMI circuit in the receiver. HDMI interfaces are notorious for this vulnerabilty.
Try powering the receiver from a UPS instead of just using a surge protector

it would help to know which receivers, but one possibility is coming down the coax... how many receivers have the satellite feed? Where does that wire run? Is there a lightning supressor on that coax?

Known problem as in permanent damage?
Or the typical problems of CEC, wrong resolution, configuration, etc?

Permanent damage. HDMI ports on many devices are very susceptible to static electricity damage.

If there is a grounding problem on the TV (maybe the electrical socket on the wall is not wired correctly) and there is a problem the circuit might go to ground via the easiest path which is probably via the HDMI cable.
Check the connections in the receptacle in the wall. Try powering the TV from a wall socket on a different circuit.
It's almost certainly permanent damage. Any significant voltage on the HDMI cable will probably damage the HDMI interface. And surge protectors won't help. They are mostly a waste of money. If they do anything at all it would be to reduce the chances of a surge on the power circuit caused by an external problem.
