5.2.6 Checking Conduction of HDC FFC Data Line
 Outline
Check whether the HDC FFC data line has disconnection or poor contact or not.
After turning off the sub and main power switches in order, unplug the power code.
Check if no electric charge is remaining in the PCB.
Refer to the "4.5.2 Electric charge checking when replace the Electrical Parts"
It is very dangerous if sleep mode functions mistakenly during the operation.
Moreover, the PCB may be damaged in case electric charge still remains inside.
Also there is a possibility of electric shock because of high power voltage applied the high-pressure part
of the power supply PCB assy. Take care to avoid contact with it.
