Prior to purchase please ensure that you understand your machines installation and calibration sequence and how to properly install and calibrate. Improperly installing or failing to calibrate your board may damage it - and returns for this will not be accepted. Please message with questions about this prior to purchasing. Please also note that sometimes boards need to be plugged in for an hour or so before powering on due to capacitors that have discharged.

All boards I sell are fully tested, and fully functional - you will not have an issue with the board, but I strongly suggest you confirm that you have a board issue and that all of your other parts/systems are in good working order, as damaged parts can cause shorts that break boards and pop the built in fuses. Due to the frequency of boards being broken by DIY repairs - I have carefully tested each component on the board and documented the result - returns made under defective reason code will be fully tested and appealed through eBay if they show damage that did not previously exist or if they pass test. Please message before initiating a return as troubleshooting almost always is able to fix the problem.
