That means you have to send your broken board to us, we will repair and test it and will send it back to you within 24-48 hours after we receive it. We are high level technicians and have huge experience with PCB (Printed Circuit Board) repair. Your board must be in good physical condition, with no components missing or repair attempts made for repair. HOW DOES IT WORK. Once we receive the board and open the box we test it and act depending on what we find out. International Buyers – Please Note.
