Not sure if our newish toppy is going faulty.
If I press the list button, the bottom of the channel list goes blocky. After that all the other menus/epg are just a mess of unreadable blocky graphics.
If I turn it off and on the graphics return to normal until I press the list button, then it starts all over again.

Are you running any TAPs ?
What software version are you running ? (press Menu, information, IRD status to find out.

No taps running - just as it came out of the box
s/w is, I think, 5.12.25

Cannot recall hearing this one before. Before you send it back you might try a computer type reboot rather than just turning off. ie cut the power while the Toppy is fully on. (not while you are recording obviously ). Leave for a while and turn back on.

Dont forget to try a factory reset as well

Seems better after a factory reset. I'll keep an eye on it.
Thanks for the suggestions everyone.
