Zenith XBV443 - FACT and FE for DVD9 (Dual Disc); System Clock of MPEG IC

3-66
FE signal becomes like the waveform 2, in case of DVD dual layer disc since the laser
beam is reflected on both layer 0 and layer 1.

The waveform and the block diagram as below show a clock input and output between IC601 and X601.
Clocks generated in X601 is output and input into pin126 of IC601.
The clock frequency is 27MHz.
If this clock is abnormal or does not appear, replace the X-tal or MPEG IC
