when the signal level is low than specified value with the
following checks.
5.
Check the focus bias check when optical block is replaced.
Focus Bias Check
Procedure :
1.
1.
Connect oscilloscope to TP (RF) and TP (VC) on the CD board.
2.
Press the
I
/1 button to turn the power on, and press the Z
(CD) button to open the CD disc tray.
3.
Put disc (YEDS-18) in and press the
u
(CD) button to play-
back.
4.
Confirm that oscilloscope waveform is as shown in the figure
below. (eye pattern)
A good eye pattern means that the diamond shape (
