PITCH angular velocity sensor (SE502 on the SY-169 board)
peripheral circuits.

Check the HALL element (YAW) of optical image stabilizer (pin
ql

, w; of CN402 on the SY-169 board). If it is OK, check YAW

angular velocity sensor (SE501 on the SY-169 board) peripheral
circuits.

Check the OIS temp sensor of optical image stabilizer (pin 4 of
CN402 on the SY-169 board).

Checking of flash unit or replacement of flash unit. (Note)
