Hi welcome to just answer.
I am sorry for the experience. The symptoms that you reporting point to a defective power supply. When the fuse fails, it would also take transformer and regulator circuit.
If you would like to go through the troubleshooting process, please let me know.
Info on the system for help with troubleshooting
You might already have the answer, the power surge is related to the problem. What I was hoping to do here was to troubleshoot the problem by using electrical measuring instruments. Do you have any of Them? Can you measure voltage across the massaging component that is not working?
