We think the HDMI connection on our box as loose as we have picture distortion periodically and our TV is registering that a HDMI cable is loose too.
It's been getting progressively worse over the past 6 months. Our box is quite old too which doesn't help.
In theory I'd call up to get an engineer out to replace the box but the call centre is closed.
It's making the TV unwatchable at times. We've changed HDMI cables (including buying new ones) and the problem still happens.
What do I do?
