When I switch on my T2 from stanby on all channels I get the error message "No programmes are currently being broadcast on this channel" with a black screen and no audio. This continues for about 5 minutes then I gradually get a pixellated picture and audio then normal service a few minutes later. Recordings are also blank at the start in the same way. I have tried powering off and on, updating the offical firmware, reseting and installing the custom firmware. I did a disk repair using the custom firmware but the issue is still there. I am thinking a damaged hard disk, or any other ideas?
