JBL EON 515XT Power Supply Repair Example We purchased the TL494CD as a potential replacement while troubleshooting a JBL EON 515XT powered speaker with a no-power fault. The repair was ultimately resolved by replacing the shorted LNK302DN at U608, rather than the TL494. When diagnosing a similar fault, the PWM controller and FAN7380 gate driver may also warrant testing, depending on the board revision and measured symptoms. Verify the original chip marking and package before selecting a replacement.
