IV. Troubleshoot of the chair—— Massage chair does not work
▲ Failure Analysis of The massage chair does not work
1. External power supply and power swith box problem
2. Fuse burned
3. The power board without DC5V power output
4. Main board problem
5. Remote controller problem
▲ Specific exclusion Fault Analysis
I. First, the external power supply and power switch box problem
Troubleshooting:
1. As shown Figure 2, please check if the power filter outlet loose? Is there AC220V power output from the flapper home?
Check and excluded.
2. Filter, is power switch itself good? I did plug the power cord plugged in correctly? Check and excluded.

So burn this two fuses There are several possible:
⑴ shown in Figure 7, "471" varistors short-circuit breakdown, removal or replacement can be solved this problem.
⑵ power switching power supply circuit board DC5V short-circuit breakdown some components, such as "4007" diode, "4.7UF / 400V"
capacitor "274" integration, exclusion or replacement can be;
