I updated my Roku Ultra and after that, the Screen Reboots to the dancing Logo and then goes black repeatedly while the white light just flashes intermittently.
I have moved it to other TVs, swapped out the HDMI cables and am using ONLY the original power supply.
Customer Support is no help and I am fed up with this product.
Thanks for the note.
We would recommend that you try performing a factory reset on your device.

Thanks. Will try tonight.
