Help Virgin sudden pixelation on all channels

I have suddenly got strange pink and green pixels using cable tuner on zgemma h5 with latest openvix and ocam. Was all working nicely then suddenly this. Could it be virgin themselves or a box problem? Anybody else with this issue?

Also pixelation in sat feed

Fucksake yeah it has is there nothing i can do. And its not pixelataton on menu screens just channels

Ok thanks

Absolute pissed off. If that doesn't work anway of fixing by removing motherboard

Let it cool down still the same. Installed wooshbuild. How is the menu ok and not pixelated

Thought that myself. Pissed off now lol have to send it back.
