Express 4k+ With Sound and Picture but black playback, eg. overlay and ui on netflix but black video

Title says it all: all playback is black, but sound and UI are there on brand new Express 4k+ 

Things I have tried:

- downscaling from native 1080p to 720p

- hard reset (remote and device)

- swap hdmi cable

- reset router

- global issue across netflix, roku, etc

- no issue on old Roku stick, nor our Roku Hisense TV

Re: Express 4k+ With Sound and Picture but black playback, eg. overlay and ui on netflix but black v

I seem to have a similar problem.

Been using a Roku Express + for years, and had a Toshiba Fire Edition tv since last year. Connected with HDMI.

Yesterday the Roku stopped working, I get a black screen. (But the sound does seem to be working.)

The interface doesn’t even come up.

Checked cords, unplugged, factory reset- each time, same:

the Roku Letters are jumping for a bit, then goes black.

P.S. This tv won’t let you select a resolution, it’s just “native”, “full screen”, “wide 1”, etc
