Burned the Throttle/LCD controller by accident

Traxonja

Hello,

My scooter DENVER/CARBON SCO-65100 250W wasn't turning ON so I traced down the problem to the BLDC speed controller. There was a cold joint on one of 1n4148 diodes, so I soldered it back and it again worked like a charm.

However, during assembly, I accidentally connected LED's power supply to the throttle controller's unused connector (the 6th pin which was not used in my case - but the connector was a perfect fit) and whoila white smoke came out of the microcontroller which is in the LCD electronics.

Now I am trying to find someone with a spare Throttle controller with LCD just like in the photo. I am willing to pay even for the one with broken LCD because I can put use my LCD glass for replacement.

Anyone has one broken to sell?

Thanks
