Got this Roku at a flea market and attempting to fix it. When I plugged it in for the first time and used a Roku remote, it turned on for a moment but when I arrived back to the TV a minute or so later, it turned itself off. The light at the bottom comes on, It is not picking up signals from the remote, but I tried turning it on from the power button on the TV and it won't come on that way either. There is a very low sound that is coming from the back of the TV on the right side. Any information, links, or tips that can point me in the right direction to fixing this tv would be extremely helpful
I got it for $20 since the lady said she couldn't get it to work. Its a 70 inch TCL.
