4.2.1 Cabinet Back / Front, TB2/3, ST1 Board
Removal
This section explains the disassembling of the cabinet (front / back), TB2/3
board and ST1 board. Disassembling procedure should follow numbers
indicated in the figure below.

TB3 Board and ST1 Board
4.2.2 Discharging Electrolytic Capacitor
The following is the discharging process of main electrolytic capacitor
(C5412) on PW1. If you skip this operation, there is a great possibility of
electric shock during the disassembling procedure.
1. Prepare the cement resistance with more than 560
Ω
/10W.
2. Contact 2 lead wires to the soldering cotton on the both poles of
electrolytic capacitor. (No polarity at this stage.)

The electrolytic capacitor (C5412) mounted on PW1 board is for
flash strobe and set to be charged automatically whenever the
power is ON. Due to this, it may cause electric shock during
the service procedure. When repairing, be sure to discharge
C5412, using the cement resistance. (See Figure 4-2,
"Discharging Electrolytic Capacitor".)
Cement resistance should be about
560
Ω
/10W.
Protect from the electric shock
with insulation tape.
No polarity
