This set has a problem with the brightness circuit.  When this set is
first turned on, the picture is black.  When the OSD brightness is
increased a little bit the picture comes on and is washed out.  I can
then turn the brightness down for an OK picture.  But if I change
channels the picture goes black again.  The OSD is still visible.  TIA
