Hi Buncey,

Nothing at all, but, who made it, Guess Hitachi didn't as they have this strange LCD passion for Vestel, and with Plasma possibly even worse. Let's hope it's LG - and with lots'a piccies, pse  - Chris.

PS - note that we have a similar on-line angles of relaxation, piccy wise, bit like our earth, in winter -awful cool, and with all that warming.

Believe most anything if pensions earned, are paid
