Hi I recently picked up a second hand Humax HB-1100 freesat box (after some advice on here about freesat boxes v openboxes). Anyway, after plugging it in for the first time it worked a treat, and has done since (all be it its set up on a second tv so only being used once or twice a week tops). Over the weekend it was on fine, i then had to pop out for an hour so i just pressed the power button on the humax remote and turned the tv off. On coming back and powering up the humax box i am just getting an error now saying "Audio/Video Buffer Underrun", and there are no channels. I have tried to do a search again for channels and its finding nothing but prompting the same error. Has anyone got any idea whats gone wrong? I messaged humax on facebook, they initially got back to me straight away asking for more details, after providing those iv had nothing from them despite chasing. Before trying a factory reset on it, given the level of support from humax, i wanted to see if anyone can suggest an alternative. I have done a quick google search but nothing i found helped.
