Confirm that the Focus error
S-curve signal at the pin28 of
IC603 is approx.2Vp-p
Confirm that the signal form
pin24 of IC603 is 0V as a
accelerated pulse during
approx.400ms.
Confirm the waveform of the
tracking error signal at the
pin25 of IC601.

Check Point
Check the voltage at the pin40
of IC603 + side is +5V?
Check that the voltage at
the pin33 of IC701 or pin3
of CN694 is 0V(a moment)?
