Focus Servo is unstable

Is FE signal

output normal in Focusing

Up/Down?

(LIC121 pin25*)

Check Pickup Read Power

is 1.3~1.7mW?

YES

Replace the LIC121.

Replace the Pick up.

Go to “Focus Actuator

operating is abnormal”

Is FDRV signal

output normal in Focusing

Up/Down?

(LIC201 pin 62)

Replace the LIC201.

YES

Focus Actuator operating is

abnormal

Is there Focus

Search control signal input?

(LIC301 pin5)

Is DRVMUTE2 signal “H”?

(LIC301 pin 35)

Replace the LIC301.

Check the connection
LPM101 pin40, 41.

Check the connection of LIC121 pin 32.
Replace the LIC121.

YES

Replace the Pick-Up.

Is there Focus

Search drive voltage output?

(LIC301 pin 51,52)

•

Check the connection of LIC201 pin 62.

•

Check the communication line between
LIC121 and LIC201.

•

Replace the LIC201.

YES

* LIC121 pin25 is MOUT2(FEP Monitor2).

After disc recognition action, Monitor port
is off. So, please check FE signal during
disc recognition.
