TV keeps flicking to black screen every few seconds

When watching TV the signal seems to get interrupted and the screen flashes black and sound stops. I have changed hdmi cable. Rebooted sky box. Changed hdmi cables. Changed picture resolution. Reset internet. changed input ports and nothing fixes it.

Hi @MichaelKing1 


Try a Reset Settings in the Q box hidden menu.
To enter hidden menu press Home and navigate down to Settings but do not select Settings.
With Settings highlighted press 0 0 1 Select.
Only Carry out the first Reset (Reset Settings) as the other two will wipe all recordings.
After the Reset you will have to re pair your Bluetooth remote If you use one.
If you cannot switch the Q box on with the remote after the Reset press the Standby button (Amber led) on the front of the box.
To re pair the remote press 1 & 3 together on the remote and follow onscreen instructions to re pair.

Make sure that you are pointing the remote at the Q box when you press 1 & 3 together.

Resetting the settings will also reset:

Audio visual settings, such as picture resolution and HDMI control
Settings changed within the hidden engineer menu, include LNB type. If on a communal dish you need to reset the LNB to SCR in the hidden menu. After changing the LNB type you need to reboot the Q box.
