Hi I've just taken delivery of my amazing Hitachi 42pd7500. Stunning picture quality. Last night was a serious drool whilst watching that underwater doco "Deep Blue" on BBC1. I'm sure all plasma viewers were thinking "money well spent". BUT, I've got a problem with my tv. Every now and again it seems to forget all the freeview channels and asks to re-scan. This only happens when turning it on from standby, and doesn't always happen. It doesn't seem to loose the analogue channels though. I spoke to the Hitachi helpline, and they said that it is an aerial problem and not a tv problem. But my aerial is designed for digital reception in weak areas. The signal strength indicator on the freeview is showing full strength! So what's the deal? Any comments please.
