HDMI Melt down

I have a Wineguard Pathway X2 Dishnet dish on my roof of my 2021 377FL, I have the cable run from the dish to the cable jack on the roof to the connection in the basement and it keeps loosing signal. So I’ve been toying with it, I know the dishnet receiver powers the pathway. It lost signal this past week end and I was checking a few things. I found the HDMI cable that runs from the IRV62 stereo to the TV extremely hot and partly melted. Now the stereo also has a RG TV cable run to, Im wondering if the dishnet receiver that is powering the dish via sat cable may be sending power thru the entire cable system and caused the HDMI melt down between the stereo and TV??? Any thoughts Very confused.

First, I hope the Pathway X2 comes down off the roof when traveling as it's not designed for road speeds. We sometimes put ours on a pole connected to the rear ladder via a "Flagpole Buddy". We and others have found the Pathway doesn't like long cable runs nor being placed in circuits with splitters and input selector switches. Best performance is HDMI direct from Walley or Joey to TV HDMI input. As far as I know ... the Walley or Joey only sends voltage out the coax connection. I would guess if voltage was present in the HDMI cabling ... it would fry something pretty quick other than just making a hot cable.

Thanks for the reply, the RV is located in a park permanently and does not move at all. After the HDMI melt down which may or may not be related I ran the 35 foot run of cable direct to the receiver from the dish. The HDMI cable has always been direct from receiver to TV. Im curious if the original cable routing thru the RV cable system was back feeding power (intended for the sat dish) thru the system and in turn sent to the stereo as the stereo does have a factory cable run to the antenna port and may have sent unintended power to the stereo thru the antenna cable.

I re-read your post more carefully and better see your dilemma. I thought the HDMI cable from receiver to TV was at fault. I just don't know about back feeding voltage. I've always run a dedicated coax from Pathway direct to Wally via a thru wall coax connector behind the living room TV. Also, we don't feed the bedroom TV with satellite signal either.

I now do run from dish directly to receiver, and as you stated I don’t feed the bedroom either. Anyways now that I am direct to receiver Im going to install a new HDMI on the stereo and see what happens. I have never in my 60 years of life and being somewhat of a techie seen a HDMI even start to get warm

There are special splitters used when passing power. There will be one port on the splitter that passes voltage while isolating the voltage from the other ports.
So with a normal splitter a very good possibility you were sending voltage where it wasn't supposed to go.
