Question about Harman Kardon AVR 130 Receiver
My amp all of a sudden has no speaker outputs, it's hard for me to believe that all of the outputs went out.... help!!!!! all else works
I know that a couple of you have had the same problem with the blowing 0.47 ohm resistors. I had responded quite a wile back, but forgot to make any updates. Kostiko is correct about the problem relating to these two 0.47 ohm resistors being blown. In my case on two different Haman Kardon models, this was true, but there could also be another issue. What i have found is even after replacing these resistors, the problem appeared to still be there. What was happening was that right after turning the receiver on, the resistors would blow again. What you need to do is replace the two small ceramic disc style capacitors on the same pcb as the fusible resistors, as they could be shorted as in my case. You could remove these capacitors completely, or replace them with a similar size of the same type, as they are really just there for filtering higher frequency noises from the power supply. You can check them with your multimeter first. They shouldn't shorted even in situe. I forget the size, but they are approximately 100 nano farads. Good luck. I have done this to my AVR135, and it has been running great for about 6 months now.

Actually, the aux. power suppy is defective. There are two 0.47 ohms resistors which are located on the main transformer output board, which are blown. The result is missing +/- 15V for the analog ICs. Replace those and the problem is solved.

This may sound crazy but i had similar issues with my 120...one thing is that there is not enough power getting to the system or there was a surge that may have blown the channels. I had a surge that blew my channels and luckily i took it to circuit city and they fixed it for free. If it is indeed the channels than i would just take it to a repair person.
