Barely 2 years old. I have black screen. Tried the unplugging and rebooting. Tried the combo buttons on remote for reboot. I can hit Netflix button and hear audio but no video at all. Anything else to try?

Tried power cycling the tv, but still, the black screen persists. So, start inspecting the wires because a loose wire can cause black screen issues. If you find any loose wire, insert it into the port properly, and if you haven't found any, then unplug all the wires connected to the tv and plug them in properly.
Also, verify that all the cables are working fine. If you find any faulty or damaged wire, replace it quickly and check whether the black screen persists.
