Hi everyone!
So my setup is like this.
Amplifier : Yamaha RX V479
Sufwoofer : Klipsch R12SW
Speakers : Klipsch 4+1
Challenge1 (background, partially solved)
Due to an incorrect handling by my moving company my subwoofer cable pin had broken down. This I did not realise till I found that no sound was coming from my sufwoofer and when I tried to touch the gain switch I received a massive shock (which I will remember for my life). I later switched off the mains and saw that the pin had broken which was clearly camouflaged by my moving company. I later took out the pin which was stuck inside which was leading to the current leakage. A new subwoofer connection cable was ordered and it fixed the problem.
Challenge 2 (leading to a new issue)
While the setup was working fine, I now saw a residual current getting generated on my amplifier Yamaha RX V479. It wasn’t a massive current but my electric tester could detect it. The power was getting leaked to my connected subwoofer as well as the TV. Most metallic touch points had a power leakage now. An expert from the Yamaha dealer came and checked the system. Said it’s an inherent Yamaha problem and won’t cause damage. Said he could earth the system which will resolve it but advised wont be necessary. I decided not to do it. The system has been running since a year without a problem.
Challenge 3 (pressing issue now)
The Yamaha amp now died. Red light blinks to protect the system. Fails to boot up showing the A1-1 DSP Pass through error. A force boot further detects an issue with PS2 PRT133 error message and goes on standby. This I understand is an issue with the power supply. The amplifier is now given to an authorised Yamaha dealer for a complete check and repair
My ask:
How can I check and exclude the fact that the subwoofer is not the culprit? Assuming that the Yamaha receiver now comes back fully repaired (at a huge cost
I know) how do I convince myself that the subwoofer is not at fault, given the fact that it all started with the broken stuck pin inside eve subwoofer, which led to the power leakage everywhere, and might have damaged the amp? I don’t have a good dealer around who can do a test of the speakers, and was wondering if I can check the subwoofer with a multimeter or something? Some basic Home checks with the power on / off? Really looking forward to some ‘homely suggestions’. To be direct and honest, getting it checked by an expert is not an option unfortunately.
Sorry my post was detailed but wanted to give the sequence of events in case that rings some bells. Thank you very much!
