Solved! Coaxial to HDMI

Jan 20, 2019
I have cable tv coax coming from the wall that is hooked to my tv. I want to use a hdmi cable that is in the wall that can connect to my wall TV. Other end is next to the coax where it comes thru the wall. What do I need to convert the coax signal to hdmi? The cable service plan I subscribe to doesn’t require a box. Thx
