How can I set the clock. We unplugged the recorder while away on holiday and upon our return and plugging it back in and switching on the time clock just flashes 00 00 all the time. Is this because analogue transmitions have been switched off? How can we get round the problem so that the flashing stops but we can still play tapes and dvds. We realise that it may no longer be any good as a recorder without the analogue signal Thank you John Saul
