37x3030DB Tv ,Just an update to my question, i rang the number other people have used 08448560730 option 2 technical help, i spoke to a nice young man called Matt, who immediately recognized the problem as a software issue as expected, due to digital switchover, i am now awaiting a call from a repairs place, chosen by toshiba who should call within 3 working days to arrange repair, I have been given a reference number to quote when they call, which enables free repair.
