Be sure to read the following before starting the repair work
1.1 Flash High Voltage Circuit Precaution
•
As soon as the front cover is removed, be sure to bleed the main capacitor.
(Bleeder resistor: 500 ohms, approx. 10 W.)
•
The bleeding contacts are the XE (+) side and GND onthe STR PCB.
Contact the bleeder resistor with GND first, then with the XE (+) side.
