Is the connector inserted normally into the CN100 ? Y Isn�t there any problem with the FPC Wire ? Y When the SLED is moved to the inner cycle, is electricity of about 1.2V output from the12pin of IC301 ? Y Is electricity of about 0.5V input through 77pin of IC100 ? Y Is electricity of about 0.5V output through 77pin of IC100 ? Y

N

Try again after a normal insertion of the connector into CN100.

N

Try again after replace of FPC Wire.

N

If the pattern of IC300 and sodering is normal when you checked, replace IC300.

N

If the time transfer R148, R153, R142 and soldering are ok is when you check.

N

If the pattern of IC100 and sodering is normal when you checked, replace IC100.

Replace PICK -UP.

The value of voltage(1.2V, 0.5V) can be modified slightly, depending on the result of power calibration or the media.
