Firestick and HDMI connector to old TV just Stopped working

The TV comes on with wide verticle colors stripes, probably a test pattern, but the firestick will not respond. I have unplugs all podts into TV as well as from Firestick and adapter. I have also unplugged from power strip with no results. I do not have any cable channels or any local TV. Only what I get through Amazon Prime and the Firestick.

Any ideas??? Thank you!!!

Hi,

Have you reset (powered on/off ) the "box" where the Prime signals and the Firestick signals are emanating from in your premises?
