You're doing all the stuff I would do. The splitter may be bad, the receiver non-hdmi output could be bad; lots to look at.
Running down bad coax in an RV is not fun...they literally build the RV around the installation.
If it was me, I'd look at the reviews for wireless HDMI (on this thread and places like the WireCutter) and test one. Don't believe any review from Amazon. Leave the coax as is.
Just my .02.
Yea I agree, I bought a new splitter today and will test it tomorrow, I’ll give update in a few days
