Last night it happened to my therion 133 DNA 200.
The device just shut down automatically, I plugged it in to USB escribe and it said check battery.
One of the cell is not detectable, I tried to reset and hard reset or change the battery from 3 cell to 2 cell still no luck.
This morning, I decided to disassemble it.
Found the problem of my therion 133. One of the cord that connected to the battery is not attached (there are 2 cords, red and black and in my case the black one).
So I managed to fix it and now it's working as usual.
Semoga bisa ya agan agan yg dari Indo.
Dibongkar manually saja. Kalau masalah dari chip nya aku rasa ga ada.
Oyah untuk menyambungkan lagi kabel nya, jelas ya butuh soder dan kawat nya dan untuk therion 133 harus dilepas deck kayu kiri kanannya.
Good luck.
