I have just ordered my 9617 p+ tv from john lewis for £1300.00 on a price match. Firstly:- 1. Is this a good price to pay considering it comes with a five year warranty? 2. I would like to try and tweak it when it arrives, does anyone know how to get into the service menu and can you really f^$" it up if you fiddle with it too much. In other words , "do you recommend it" some feedback would be great. Cheers in advance Elvio, London.
