Hi @elmo1234 ,
Hopefully there is enough slack in the cable to allow for a new connector to be wired in.
Here’s a video that shows how to wire a HDMI connector that may help.
It also may depend on what type of HDMI connector is being used.
Connectors are also available from here and here (supplier examples only)
if doing this yourself seems too daunting contact a reputable, professional electrician who also does data, TV wiring, security installations etc and ask for a quote
