I have 2 Rokus and I've failed to find articles/feeds to see if the subject is a known issue. It seems that my devices are '...not eligible for agent for support' [separate issue]
TL;DR - recent update seems to have caused video issues but I need to rollback the update to confirm
1. 3920X Roku Premiere
S/W version 12.0.0 4184-91
2. 3920EU Roku Premiere
S/W version 12.0.0 4184-91
- Roku 1 connected via HDMI to Soundbar (Philiips Fidelio B5) HDMI input port
- From there the connection to the HDMI (ARC) port on the TV (Sony Bravia)
This setup has worked without problems since I bought the 3920X a year ago and I have not made any setup changes to Roku, Soundbar or TV.
Since the latest 4184-91 update applied on the 20th the video (Netflix, Sky News or just the Roku homepage) plays OK for maybe several minutes but then flashes different colours before going to a blank screen and then the picture returns. This issue the repeats every few minutes.
Fault finding:
- Checked all cables seated properly
- Used different cables - Roku to soundbar and to TV
- Swapped the 3920X for the 3920EU
- Direct connection to TV, bypassing the soundbar
With the bypass (4) the Roku worked so I assumed it was the soundbar connection. I then connected my MacBook to the soundbar in place of the Roku (MacBook to soundbar, soundbar to TV ARC port. I then mirrored my Mac screen to the TV without problems and then played a movie from the Mac without problems.
I would like to go back to the previous version to 100% confirm that before I try anything else but I can't see a way to do that
