PCB’s Motor Combo IC

July 9, 2012

If your PCB’s motor Combo IC was burnt, please check the burnt part as the below photo.









Part 1 burnt, it was caused by head-stack problem.

Part 2 burnt, it may be caused by head-stack. However, in most cases, the problem was caused by plug in the wrong electrical power.

If your motor Combo IC’s burnt position was on the part 2, swap PCB may help. When you swap the PCB, please confirm plug in the right electrical power.
