razer Deathadder V3 Pro wireless mouse problem: works for 5 seconds then shuts off.

Hi everyone, my mouse broke when my brother angrily threw it. I took it to a repairman I know, and he said the sensor pins were broken. He soldered two of the broken pins, and the mouse worked after that. However, it doesn't work wirelessly. Actually, a white light blinks, and it works wirelessly for 5-7 seconds before completely turning off. I have to turn it back on wired. Has anyone experienced this problem? I need someone to help.
