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.
- 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.
