How to repair Pangu fishing lamp?

There just happened to be Brother Pan's lamp, which was just changed.

First, you need to make sure what's wrong with the battery. Lamp holder? Control circuit? These can be bought on a treasure.

My first question is that the button is broken. At first, I need to press more and more occasionally, and the number of times is getting slower and slower. I bought a four-legged button from an electronic equipment store, cut off two feet that communicate with other feet and replaced it with an electric soldering iron. It is normal. If you can't operate like me, I suggest buying a control panel directly. Not expensive.

The second problem is that the lights are getting dim, so I changed a white lamp holder called 10w on a treasure (in fact, it was warm white, attractive but dark, and the new one was cold white and brighter), and later I bought a purple lamp holder to replace the original blue, because I always felt that the blue light was dazzling. Purple light is not as dazzling as blue light, but it is much darker than blue light.

Next is the battery. I bought a battery called 9000mah and changed it directly. Now I can use the new lamp holder for 6-7 hours.

Both ends of the lamp can be turned on. Both ends need to be unscrewed when changing. There is a lamp holder at each end. The long line is blue and the short line is white. Note the three connectors (white light, blue light and battery) on the control circuit board. There are two circular plates in the two lamp holders. White light is a circuit board and blue light is an empty board. A long screw passes through the battery and is fixed on two plates to prevent the battery from moving. It is found that the design of this board is very unreasonable and the assembly is very difficult. When the battery was disassembled for the second time, the board was not installed at all, and the battery was pressed with double-sided tape and gasket, which made the assembly much more convenient.

In fact, if you change like me, it is still not cost-effective. Just buy a new one. A certain treasure is only 80-90 yuan. If you only want to change one of them, you can consider buying accessories to replace it.
