Hi @Hunter94

@is it any hdmi port and any connected device ? It's not an issue I've seen reported previously...... also not seen it on my gen 1 or gen 2

also have you tried different hdmi cables

I'm also having this issue. All HDMI ports. Reboot and power off for a few minutes has not resolved either.

65inch on UI 3.79.0

I've had a similar issue with my firestick once where selecting the firestick hdmi caused the picture to flick back and forth between the firestick and sky Home Screen. I resolved this by pulling the power on the firestick and letting it boot back up

x box x not connecting to sky glass

Hello - help! I have looked through the threads and cant find an answer as to how to get the Sky Glass to recognise my X Box X. We have tried all the HDMI inputs. made sure the recognise old devices is both on and off but nothing. It recognises a connection but that is it - screen remains blue and it mentions the compatibility?

Thank you for your help!

Glass HDMI Fault

Anonymous — Sun, 21 Dec 2025 13:53:29 GMT

Today my HDMI won't connect all been working OK until now. Selecting HDMI just flashed up on screen as if connecting but then reverts to the home screen.

1. Have restarted the TV

2. Have restarted the Apple TV

3. Have swapped out the Apple TV with a second unit

3. Have changed the HDMI cable

Apple TV's work fine on my LG OLED.

Seems a fault with Glass, could be software glitch or faulty connection at the HDMI port but not touched that in weeks.

Other than calling Sky with suspect faulty tv any ideas?

I been experiencing some issues with my gen 2 and firestick this last week ..... when I try and switch to the firestick it flicks between the firestick and the Home Screen constantly until I pull the power on the firestick

there was a thread last week that posted on with another few users with the same issue

I will raise in the closed forum

@Jporch316

Thanks for update, don't understand this as there has been no Software update unless Sky has switched something in the background.

I am getting a bit fed up with Sky once again there are still so many glitches and with all the various app issues 🤨

There's not 2 days that pass where something isn't right requiring faffing about to watch something. So annoying.

This is a joke why has this not been fixed 😡😡 I am having to restart the TV every time I turn it on!! My Xbox and Firestick are affected. So a poor issue to be having and not an urgent fix in place. You push and force updates on us and they break the TV.

this has been since the 11th December sort it out

Hi @Chardie81

@I've not had this issue for a week or two now since I rebooted my firestick with the tv on the hdmi channel.

you don't need to restart the tv only the device that's affected (by pulling the power to them )

Had the same issue here on a Gen1 65" before Christmas, then it was then fine for a week or so but it's back to glitching when selecting a HDMI input since yesterday.

Only a reboot of the TV fixes the issue, rebooting the devices doesn't help. Selecting a HDMI input works after a reboot but the issue returns once you go back to the homscreen and select a HDMI input again. The devices (Xbox, Shield and Switch) are all fine on another TV.

@KevNewMedia

When is this being fixed!!!!

A simple task to activate a HDMI connected device and I have to faff about for 10 mins powering this and that and unplugging hdmi leads. It's not good enough.

Can only connect to my Amazon sometimes

I get the home page flashing on and off. It's very off-putting

@DadsArmy68

Sorry but your post isn't very clear as to what device you are having issues with and how this connects to Sky so is this a Sky Broadband issue as you have posted this in the Sky Go forum ?

Re: Can only connect to my Amazon sometimes

DadsArmy68 — Fri, 09 Jan 2026 19:37:39 GMT

When I'm on the sky home page I scroll down to apps and inputs, Im connected to HDMI 3 for my Amazon fire stick, when I try to connect it goes back to the homepage and starts flashing back and forward, it happens maybe 6 or 7 times outta 10
