Step-by-Step Guide to Fixing the Power Switch
Step 1: Gather Your Tools and Replacement Parts
Before starting, make sure you have the following:
Replacement switch: A 20mm 4-pin rocker switch
Screwdriver: To remove the screws from the speaker casing
Tweezers or pliers: Useful for handling small parts and clips
Glue remover or heat gun: Helps in removing the glue holding the switch
Drill (optional): Can be used carefully if the switch is tightly stuck
Step 2: Disassemble the Speaker
Remove the screws: Start by unscrewing the necessary screws from the back panel. Avoid removing unnecessary small screws.
Detach the front panel: Once the screws are removed, gently pull the front panel off. This will expose the faulty power switch.
Locate the power switch: You’ll see the old switch surrounded by glue.
Step 3: Remove the Faulty Power Switch
Disconnect the wires: Carefully detach the existing wires connected to the old switch.
Remove glue: Use a glue remover or carefully scrape off the glue securing the switch.
Take out the switch: Press in the small locking clips on the sides of the switch and pull it out. A bit of wiggling may be needed.
Step 4: Install the New Power Switch
Insert the new switch: Fit the new 20mm 4-pin rocker switch into the same slot.
Reattach the wires: Ensure you connect them exactly as they were on the previous switch.
Secure the switch: If necessary, apply some glue to hold it in place.
Step 5: Reassemble and Test
Put the speaker back together: Reattach the front panel and screw everything back into place.
Turn it on: Flip the new switch and check if the power light turns on.
Play some audio: Confirm that the speaker is functioning properly.
If everything works as expected, congratulations—you’ve successfully fixed your PreSonus Eris 3.5 power switch!
