One and a half weeks into ownership and I've run into a problem with the Hitachi PD6600 - when turning the set on it will be fine for around a minute and then the screen will cut out. The sound will stay on but none of the on-screen menu's will come up. Dead..... When turning off for around 5mins and then turning back on the screen will be fine for around a minute and then cut off again. I thought it was too good to be true. I called MasterCare and they've booked an engineer for monday. I could understand if this was the first time I'd had a problem with a tv - it's not. It's the THIRD. Both TV sets previously (Sanyo, Toshiba) both went after 2 years with the exact same problem and now the Hitachi, which lasted one and half weeks. The set hasn't even been on that much as I was being extra careful. Can anyone suggest what the problem is? Or has anyone experienced a similar problem and found a soloution? Is it something simple like an option on the menu has been turned on?
