Unwatchable glitching
My tv is glitching so badly from the bottom of the screen upwards when watching certain channels or certain recordings. It makes them unwatchable and then we end up just having to delete them. Ive gone through all the help on the app with the box and broadband. It says i have an issue but just keeps telling me to restart the box which i have done numerous times and im trying to chat to anyone online but it doesnt allow me to use that option. Help please!!!! I think i need an engineer.
