HI Ron,
  The schematic says and I quote,
"This set employs an Auto Kine Bias circuit.
There is no adjustment to be performed."  It does have a service
menu but that feature is no in it.
However to get into it you simultaneously press the front panel
menu, volume down, and channel down
buttons. It doesn't say how to exit but
probably just power off will do it.
It only shows six adjustments to
be made in the service menu --
Factory mode
Environment
Brightness
Maximum Volume
Vertical Sync
AC Power
    Hope this helps some.
      Dave Routson
