HDMI cable/port degrading? (self.techsupport)

submitted 11 months ago by CameronDev to c/[email protected]

7 comments fedilink hide all child comments

I have a moderately long HDMI cable running to a screen that has worked for quite a while. Recently the screen lost its connection. I replaced the cable with the exact same model of HDMI cable, and its all good. The cables arent frequently inserted or removed, and they are otherwise in good condition. I have no idea how or why this could happen. Any ideas?

Corrosion? Connectors sometimes get a little crusty over time, especially from humidity. I keep a can of deoxIT handy, it works wonders. You can spray a little in the connector and the socket and plug/unplug a few times. I’d be curious if your old cable would work again if you tried that.

Worth a try, but not a particularly humid area. I did plug them in an out a few times while i was investigating, maybe worth trying some more.
