N78 flashlight is bright and shutdown is also bright

The n78 flash light is too bright to be turned off. The power off is also bright. It is not bright only when the battery is switched off.

A few days ago, when I got home and took out my cell phone, I couldn't close the flash. This is the second time, because the first repair took nearly a month. I don't want to deliver the repair work this time. I decided to open it and study it myself. By the way, clean up the dust and learn about the internal structure of n78.

You can search for the disassemble video in a specific way.

Finally, find the location shown in:

The above two round golden contacts should be the power of the flashlight. We only need to paste one of them with an insulating tape. In this way, the flash will never shine ..

 

I hope you can express your opinion. After all, this solution is not the perfect solution. I don't know which part of the flashlight is broken. You can tell me which prawn knows.
