I have a FlashForge Finder and the motherboard shorted out. Unfortunately, it seems there may be multiple shorts as removing the single resistor which seemed to be the issue did not fix anything (or, the resistor was vital), and the printer still won't turn on anymore.

I have never really tried the online forums for 3d printing - is there anywhere online where its possible to buy perhaps used parts or something? A new motherboard is $200+ on the FlashForge website, so I might as well just buy a whole new unit if it comes down to that. Mechanically, everything is sound though, so I'd rather not buy a new one and have to get rid of a perfectly good printer.

Thank you in advance to any help!
