Solved! Rca to HDMI Adapter is not working, why?

Dec 31, 2021
I tried connecting my RCA to HDMI adapter to my tele and it worked once, now its only showing it has no signal. Is it a problem with the adapter and I have to carry it back or a fault on my part?
All cords were connected properly, I checked and double checked.

The Adapter box cord(not the HDMI but the one to plug) was hot.
