btw with most modern tvs using side mounted hdmi on the pcb directly, it’s bad solder joints causing these issues. Resoldering the connectors fixes it like half the time.
usually you can get some form of signal flashing back at you if you jiggle the ports just right. And generally it should be pretty obvious when they have bad solder joints. They’re usually completely loose and can be seen flopping about just a little.

Interesting, I had ruled this out as likely because all 4 HDMI ports didn’t pick up a signal, but I’ll take a closer look at the board I pulled out.
