Question about Harman Kardon AVR 100
AVR 110 turns on and then after 1-2 seconds clicks back off. Checked all fuses I could find inside (5) and they all are intact.
FIrst couple of times this happened unit would stay on for 5 minutes then shut off. I would push power button and then picked up the front of the unit a couple of inches and dropped it. This banged it into working.
Does anyone have any idea as to what this could be???
Do you get an indication on the display where the point of failure might be? It would show up on the LCD speaker diagrams just before shutting off.

SOURCE: unit wont turn on
The board you are looking at is the standby cct and power switching PCB. It sounds like that is working, so you have probably lost power to the transformer primary or the transformer is open circuit. Check for blown fuses and replace with exact same type and rating.
Be sure to unplug at the wall before touching any internals!!
If you can find no blown fuses, the power transformer may have failed. Good luck, get back to me here is you need any more advice. Thanks for using "FixYa"
