Question about Harman Multimedia HS 300 System

1 Answer

Harman Kardon HS 300. I get no sound out of it after forgetting to turn the unit off overnight. This has happened several times and sound control doesn't come back for days or longer. Why does this happen and how can it be fixed.

I would need more information, such as, is the unit still on and functioning with the exception of no sound, or is it just dead? For more information, please visit my website at audioserviceclinic.com. Thank you.

Hs 200 harman kardon stop working


Check the capasitors in the power supply. These often have a popped top surface, not flat like normal. These need to be changed. It can be as many as 10-15 bad ones.

No sound out the front speakers Harman kardon HS 250


If everything else works fine, than change the 47uF/50V electrolytic capasitors in the power supply, primary side. There are only three of them. C505 is the one that's always bad, but change them all to be sure.

My Harman Kardon HS 250 has power (as indicated by the power light) however the front screen is blank and no sound is coming from the speakers?/


Possible that the microprocessor stage is not working and is not conveying any display to the unit.
remove the cover and check the 5Volt rail to the mP section. If the voltage is absent check on the 5 volt regulator.
If present and there is no life, then check for oscillatiion of the crystal, might need a CRO to confirm if the mP is working or the clocck signals are present, if data tranfer is present. If not mP is faulty.Take help to confirm and find a source, might be approach Harman Kardon.

Settings lost when powered off. My Harman Kardon AVR 300 forgets all its settings when powered off. All radio station settings are lost, but also the input selections eg. cd=optical 1 etcetc. I guess there...


Most of these HK receivers have a 3.6v rechargable battery on the front panel board. If the battery dies, you lose memory when it is turned off/unplugged/power failure. The battery is soldered on the board. Not replaceable by the user unless you are a tech. It should keep memory if left in standby.

Power botton not responding


If it's not ejecting or responding to any of the buttons on the unit, or the remote, but is able to play a DVD, the display microprocessor(computer) within your Harman is damaged. For more information, please visit my website at audioserviceclinic.com. Thank you.
