This manual is very useful because it presents the technical specifications of the cd player, including the manufacturer of the reader, this helps if you need to replace it. It also displays the settings and layout of the circuit.
Manual was a good representation of service infomation for the EWV404. It worked well for my repair.

DISCHARGING OF THE FLASHLIGHT POWER SUPPLY CAPACITOR (DCR-PC105/PC105E)
The power supply capacitor (C6606) of the ST-084 board is charged up to the maximum 300V potential. There is a danger of electric shock by this high voltage when the capacitor is handled by hand. The electric shock is caused by the charged voltage which is kept without discharging when the main power of the unit is simply turned off. Therefore, the remaining voltage must be discharged as described below. 4-1. PREPARING THE SHORT JIG To preparing the short jig. a small clip is attached to each end of a resistor of 1k�/1W (1-215-869-119) Wrap insulating tape fully around the reads of the resistor to prevent electric shock.
