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.
