Printer: Prusa I3 Pro b
When I disconnected the wires from the thermistors of the hot bed and the extruder one (on the gt2560), while I had the printer turned on, I saw a small spark in the circuit and smoke began to flow. I turned it off quickly.
Now the lcd does not turn on and I do not know if I have burned anything else.
Please tell me what I can do.
Sorry for my bad English, I'm translating this with the google translate

Hi,Could you show some pictures of the control board when power is on?I wanna know which parts of the board are burned.

m2303adn was burned,
It is clear that this component is burnt

In this case,you can contact your seller who sell you this printer about it.
