I Bought brand new in box JVC ROCU TV model 50LBU591U few years back.Opened it up recently & no REMOTE INCLUDED! Bought a ROCU remote that didn't work..so trying to find out if there's a specific remote I can purchase, what where etc?
You can go to your local Walmart and buy Wifi voice remote separately in universal remote aisle for $20 or $30. It won't work right out of the box it has to be paired with Roku tv. Or you can buy Roku tv IR remote from amazon:
Which will work directly out of the box.
@Tivoburkee provided the info re available remotes you can use with your JVC Roku TV.
FWIW, fleshing out some background information:
