Note 2
Be careful from electric shock hazard because the capacitor
(C6512) for the strobe is exposed. Be sure to positively dis-
charge the capacitor if it is energized by short-circuiting a
resistor (10 - 22 k ) connected at both capacitor terminals.
Please be very careful when doing this job.
Note 3
Make sure that there is no slippage between the LCD panel
and the backlight, the four spots are locked with hooks
securely, and the sheet is placed in the correct direction.
