Basically, all Harman Kardon amplifiers (including subwoofers) show power supply issues after a few years

Posted by jpluimers on 2019/07/26

Experienced first hand myself, all my Harman Kardon amplifier equipment (including subwoofer) have shown power supply issues after about 2 years of use.

Signs are devices not powering up any more, giving only a limited amount of power (for instance a subwoofer only blinking the power led), or intermittent shutdown failure (more often when it is warmer than 22 degrees Celsius).

There are companies making a living of just these power repairs (for instance Audiocare.nl who git all my defective equipment to work again for about EUR 100 per device: [WayBack] Harman Kardon – AudioCare.nl).

This is how you remove the power supplies:

The biggest issues are failing capacitors, and glue becoming conductive.
