Hi thanks for your reply. I tried this but no luck the TV appears to be stuck on TV1 to TV9 or the SAT option using the buttons behind the small screen. I've tried pressing all the buttons in different orders hoping to get the DVD mode appear again but nada!
Any other ideas - maybe need to buy a 2nd hand handset which are pricey online I think about £80 - £100. If it doesn't work with that sell the handset again and try getting a TV engineer look at it. If that doesn't work sell the TV and buy a new one.
