Problem with Tongsheng TSDZ2: display leds all lit up on startup

[Ssciberras]

Just my luck, after 800km+ my year old tsdz2 packed up. I left it parked, when i went back after a few hours i find the display on, with all leds lit up.

i tried switching off, with no success, so i removed battery. I charged battery (i thought it was around 20% full, but could not check) and left bike off without charge overnight, hoping this would hard reset the display and controller.

Unfortunately, no luck: display is still the same, and motor is not doing anything

i have a 36v 350w motor, with a VLCD5 display.
Would you think it is the display or the controller?

If i change display, and get the Bafang 850c would it work without updating to the opensource firmware?

Thanks

I doubt changing display to Bafang will be compatible you need one of the two Kuenteng models.
