Newbie here.
I have an Onkyo TX VS373 that keeps burning r543. I have a schematic with the service manual in pdf. r543 is on page 37 and 38 of the schematic and is in the speaker circuit. I replaced r543 with a 330ohm 1/2 watt carbon film resistor and capacitor c509 which was burned also. When I reassembled and tested the unit it burnt again. I am not sure what to check for next.
It may help to know how the receiver went out to begin with. My son thought he would set one of the speakers outside to listen to as he swam in the pool. He turned all the other speakers off except for the one he sat outside and cranked it up. Well didn't take long and ....silence, system shut down and would not power up.
I will try and attach the pdf for anyone that may be able to help.
Well the file is too large to attach. I can send it email to any one that can help.
I appreciate any help I can get. Things are tight and I don't want to buy a new receiver.
Thanks.
