Hi Shaun,

It's a thought as have a Bush LED24970DVDFHD Vestel using 17PW80 and 17MB62-2.5 where set cuts to S/by maybe twice a day, otherwise perfect - Chris

Would suggest folks give some idea as to what they might be talking about, as even Quuk folks can't guess everything - Just a thought.

hi all
latest update to fault
reset via s/menu then run ,reset again then setup in swiss country and run it,reset again then setup in english
seems to have cured it been running 24 hrs without problem now.still no sign of software anywhere can only think different country has forced software to come back out of original process-er
