Coax outlet in one room has no signal. How to diagnose/fix?

I have two coax outlets in my condo. One works fine and has active Xfinity signal. The other has no signal at all. I checked behind both wall plates and each has a single home-run cable going into the wall with no splitters. So they must connect somewhere further upstream that I can't easily access. Is there a way to test and diagnose a dead coax outlet without access to wherever the lines terminate? And any tips for getting Xfinity to actually dispatch a tech rather than routing through their automated troubleshooter?

Nope.
You're better off running a m2m from the coax outlet and using a 2/3/4 way splitter.
There will be "some" signal strength loss, noise and 'jitter' - but its better than waiting weeks-months for a field tech to come out or have your property manager to have something done about it.

Hi there, @user_6almlo Thanks for reaching out . I can definitely understand how frustrating that must feel, especially after the thorough troubleshooting you’ve already done on your end. It’s clear you’ve put a lot of effort into narrowing things down, and that really helps. From what you’re describing, it does sound like that inactive outlet may not be connected at the main distribution point or could be disconnected somewhere upstream. Without access to where those lines terminate, it can definitely make things more difficult to fully test but you’ve already ruled out quite a bit by checking behind the wall plates, which is a great step. Since it's been a few days since you last posted, are you still needing assistance?
