My Hisense EN2A27 remote is not working. Just stopped while tv was on. Changed out batteries, but nothing. How do I get it to communicate again with the tv?

My screen is black and not responding to the reremote.
we can hear but not see what is going on

Using your cellphone camera point the remote at the camera and press any button. You should see the ir led on the remote flash. If not the remote is defective. Unfortunately this particular manufacturer has a poor reputation for customer service if this unit is still under warranty. I would suggest purchasing a universal remote rather than waiting the months it takes them to resolve your issue. If the remote does flash on camera then the t.v. is at fault and it needs repair.
