Pic 7 Main board & DC5VA power switch part schematic circuit diagram
The connection of the DC5V power switch and can not start massage problem
：
As Pic5 power board get AC220V power input to CON1
→
Then the good power board will through 5VA & GND output DC5V
to main board
→
then main board MCU& Controller have DC5V voltage
→
By controller start it
→
Starting signal through power board
CON306’s JDQ control relay & 105LM coil to make DC5V power Close
→
Then CNON102 get AC220V
→
Ringlike Transformer 9660-A33 get
AC220V input power
，
So it has AC110V
、
AC28V
、
AC14V etc ..output power
→
Main board get all voltage it needs
，
then the massage works
as noraml
，
with out DC5V can not start massage chair .
