Looking for a little help here. Had a power failure that lasted about
three hours. When I powered this set back up, it had a blank block
box in the lower right area of the screen almost like a PIP feature
but I don't think this model has PIP. I don't have a manual for this
set and can't find any reference to this in the on screen menu.
Re-setting to factory defaults is no help. Can any of you offer some
assistance??? Please????

Tnx,
Tom
