Battery management IC had gone. I fixed this problem many boxes already.

Thank you so much, I will contact them.

No. I have done external switch but still no working, not show in Escribe.

it is not fitment issue because i took the board out from body and push directly on the switch but still no work.

Thanks for your reply. I have soldered 2 pins to external on-off switch but still no work. Firmware is 1.2 SP5, already flashed many times but still no work. what i can do now?

Please find the red circle in the photo. I used Buzzer function in the meter, when i pushed switch, meter will sound "Beep". It seems like the board did not detect signal from the button.

I have tested switch outside the body already, it's same result. also open the top cover and clean already. the button work properly (checked by Buzzer function in Meter) but the board did not detect signal from the button.

My friend sent Finder167 to me for repairing. I found that Fire button is not working but it can fire via Escribe program. I tested the button with multi-meter already and the button work fine. Does anybody have an idea to fix this problem? Please help. Thank you so much.
