Einleitung

This guide will demonstrate how to replace any of the push button switches on the circuit board. Each button has four solder pads to desolder. When replaced these must be in the correct orientation in order for the device to work. For soldering help, follow the How to Solder and Desolder Connections guide.

    • Remove the five screws (13mm long, 6mm head) attaching the Base Cover using a Phillips screwdriver (Ph2).

    • Remove the two screws (13 mm long, 6mm head) attaching the Base Cover using a T10 screwdriver.

    • Locate which button you wish to replace.

    • On the back of the circuit board from the button, there are four solder pads with the designation "SW" followed by a number.

    What changes required if we need to run this PCB on 220V? My PCB number BL770

Hi! I changed the “power button” and when I plugged it back, it went on without the press of the button, and it didn’t work. Think I may have made a lousy soldering job… :/

Got a dead BL780. Pretty sure it’s the power switch as it’s been harder and harder to push to turn on. Going to attempt to replace on the board. I’m guessing that it’s a tactile momentary switch and that the board controls the power activation instead of the tactile switch being a push on/push off. Any insight would be appreciated.
