I realise there's an abundance of similar posts, but there's no actual solution in any of them.
I have a Roku Premiere that as of this morning is displaying an Insufficient Power warning (fine last night, nothing has changed) The official Roku USB cable is plugged into the official Roku USB adapter. I have tried different cables and different adapters to no avail.
After powering on, the white light is solid for a minute or so but then begins flashing intermittently.
I have performed a factory reset but the issue remains. Does this mean the Roku unit itself has had some kind of glitch and is it now only fit for the bin?
Possibly. It could be the power supply is going bad but the device itself is good. I could be an issue with the outlet into which you have it connected. It could be the device itself. I suppose it could even be the USB cable. I'd think the power supply as the problem, but as stated, it could be a series of other things.
If you replace the device, I'd hang on to the old one, just in case it's the power supply and the device itself is good.

I've tried multiple outlets, cables and adapters. Even hooked it up to a projector using a different HDMI cable (and USB lead and 2.4A adapter) just to rule out every possibility, so it probably is the device.
I've ordered an Express 4k to replace it and i'll test the Premiere with the new power supply once it arrives.
