TIZENTV black screen despite looking healthy in AppSpace portal

​@reada thanks for the details. Since the devices show Online / In Sync, the Appspace connection itself is likely fine, so this is often a device or content-side issue.

A couple quick things worth checking:

• Tizen version – the Appspace app requires Tizen 4 or newer. Older versions (like Tizen 3) can stop displaying content after cached content clears.
• Channel test – assign the same channel to another Tizen TV that’s working. If it also shows black there, the content itself may be the cause. 
• Device task refresh – from the device in the console, try:
  • Restart App
  • Redownload Content
  • Resync Script
  • These can refresh the app and content locally.

Let us know how you make out here, if this does not work then if you could provide: 

• Tizen version on the affected TVs
• Appspace app version installed
• Whether the channel has multiple cards or just one
• If the black screen appears immediately or after a few seconds

That’ll help pinpoint whether it’s a version, content, or playback issue.

Thanks Dawn, looks like the PowerBI report had broken.
