I'm sorry to hear about the issue with your XDJ, but unfortunately nobody here is authorized to provide you with the details or instructions on disassembly or repair of your player. I don't want to suggest you replace a board only to find that the problem still exists, or for you to inadvertently cause additional damage to the unit. Please contact a Pioneer DJ authorized service centre in your region to have your hardware inspected and/or repaired.
