PreSonus Eris 3.5 No Power Repair | Dead Ants Inside the Power Switch!

In this repair video, I troubleshoot and fix a PreSonus Eris 3.5 studio monitor that suddenly stopped powering on. The speaker showed no signs of life—no power LED, no sound, and no response when switched on. After opening the unit and performing a careful inspection, I discovered an unusual culprit: the power switch was packed with dead ants. The insect debris had contaminated the switch contacts, preventing proper electrical connection and causing the monitor to appear completely dead. Watch as I: Diagnose the no-power condition Disassemble the speaker safely Inspect the power input and switch circuitry Clean out the ant infestation from the power switch Test the switch operation Reassemble and verify that the monitor powers up normally again This repair is a reminder that even small insects can cause unexpected electronic failures, especially in equipment stored in warm or humid environments.
