Thanks Johne - took it into Curry's where it was bought - they were excellent - I didn't have my mother's receipt but details of the transaction from nearly 2 years ago were there on the pc screen, so it is till under warranty (3 years). We tested the tv and same thing so they have taken it in and to go off to their service centre. Either repair or vouchers (as it is a TEAC and not a Sony/Panasonic this is a very likely route).....they also have lent her a good loaner. And very nice about it.
