Was wondering if anyone had one and has opened theirs up before or have schematics? I get the rror code of 279 everytime I try to measure anything and I know that means to send it in. However, I opened it up and it looks like a component has broken off on the board where the fiber optic for the laser comes in and connects to the board. If anyone has one and could tell me what component goes there it would be greatly appreciated.
