The JBL Partybox 100 is not turning on, and the power indicator is red, possibly due to a power supply issue. The context mentions voltage dropping over time, indicating a failing power circuit. A faulty MOSFET or transformer might be causing the issue, preventing stable power delivery. Additionally, there is no standby voltage, which suggests a failure in the power regulation components.
