So last night my tv turned on fine and was working then after a few mins it just went off and I couldn’t turn it back on with remote, remote app and by the tv itself. It showing the red light on bottom going on and off and nothing. I’ve tried unplugging it for a while and still nothing.
Usually the red blinking light means some sort of internal hardware issue. Normally have to contact the manufacturer of the RokuTV if under warranty or a TV repairman (service center) if not under warranty.
You can try a couple of things first.
1. Unplug TV. Press and hold the manual power button for 1 minute. Then plug back in and see if restarts.
2. With TV plugged in, press and hold the Reset button for 30+ seconds. (The button may be a pin hole button labeled reset - look near USB port or on back of RokuTV).
If neither of the above works, then your RokuTV is probably in need of service.
So I tried all the other suggestions others mentioned but none of them work. It’s still doing that on and off flashing. Won’t turn on with or without the remote. Tried to reset it and nothing changed. It’s been a couple weeks maybe a month or so and it was working fine I turned it on one night and watch tv for a couple of mins before it just switched off and wouldn’t turn back on just the red flashing light.
