Distinguishing method between New Tuner and Old one




                                    If this frame is gray color (old : black),
                                    then the New Tuner (S/N:4859719730) is used.



CAUTION
  -   2 Tuners (Old:4859717030, New:4859719730) are not interchangable.
      Each tuner should be replaced with the same one.
  -   But Main PCB Assy ( Old & New ) are interchangable by itself.
