Thanx - yea i've done all that & have a hand held meter too & all seems to be fine but i've got a bit of an ongoing issue with Panasonic & a quite expensive Freesat Plasma who's warranty is fast running out!!
they've had the set in for repair, been out a couple of times, changed the sat receiver but still no better so they're now pointing to the dish & i think i may have to bit the bullet & get it lined up correctly with a test sheet so Panasonic can't pass the buck anymore!!
it's been a cracking set & i could seriously do without replacing it
