Sky Q shows black screen after returning from HBO Max on Panasonic TV — when will TNT Sports work again?

It sounds like you briefly lost the live TV video when returning from the HBO Max app, but the channel came back after pressing Home. That usually means the Sky Q box or the TV temporarily lost the video source or the Sky app/decoder needed to re-establish playback.

What likely happened

• Switching apps (HBO Max) changed the TV input or put the Sky Q box into a different state. When you pressed Return the box tried to go back to live TV but the video stream didn’t resume immediately, producing a black screen.
• Pressing Home forced the Sky Q box to redraw its UI and reinitialise the live tuner/stream, restoring image and sound.

When TNT Sports will work again

• It should work normally the next time you switch to Sky Q live TV — no permanent problem. If the box and TV are powered and connected, selecting the channel or pressing Sky will resume live TV.
• If you repeatedly see a black screen when returning from apps, try these quick fixes:
  1. Press Home or Sky button (this refreshes the Sky Q UI).
  2. Wait 10–20 seconds after switching apps before returning to live TV.
  3. Use the Sky remote’s TV button then Sky to ensure the TV input is on the Sky Q HDMI.

Troubleshooting if problem recurs

• Restart the Sky Q box: Settings > Help > Restart box (or unplug for 30 seconds).
• Restart the TV (power off, wait 30s, power on).
• Check HDMI connection: reseat the HDMI cable or try a different HDMI port/cable.
• Disable any HDMI-CEC/Anynet+ features on the TV temporarily — sometimes CEC confuses input switching.
• Ensure the Sky Q box firmware is up to date (it usually updates automatically when connected to the internet).

When to call support

• If live channels often show black screen, or audio fine but no picture, or the box fails to tune channels after restarts, contact Sky support or submit a fault through your Sky account.

If you want, tell me:

• whether the black screen is audio-only (sound but no picture) or completely silent,
• whether the problem happens every time you switch apps or only occasionally, and I can suggest more targeted steps.
