I have bought a bigger TV moving from an LCD to Plasma. Great picture but some of the stations have their screen displays way on the right or left edge and it is not showing up.
I have tried different screens and " Full " and " screen 2 " seems to be the closest but can't improve it enough.
Some of the threads seem to say that's a Vierra common problem and referring to the service mode to turn the overscan off but I have not found anything there that jumps out adjustment wise .
Any idea's before I mess up the TV settings?
