Greetings to diyAudio community!
So I've made a huge crap today!
Needed to change some electrical plugs behind my hi-fi Technics system but had my mind elsewhere and forgot to unplug it before so I had it on standby.
What happened was, when removing the power amp controller (SU-C909u), I've disconnected the cable that links it to the power amp that was on standby and when removing it the amp turned on immediately and I could hear the little feedback from the speakers from the working amplifier.
I've then disconnect everything and made the necessary changes.
When putting everything back together the amp didn't worked anymore.
Turning it on, only the left lamp from the meters turns on, the led "operation" comes on after a second as it should but no sound, no movement from the meters as well, its virtually dead 🙁
Any Technics maintenance guru out there with some guidance helping me to bring it back to life?
I would be very thankful
Cheers

looks like you have popped one side of the board, the best thing I can suggest to start with if you are handy with a screwdriver would be to pop the top off of the power amp and look to see if you have any signs of burning or popped caps. pictures of the inside would also be a good start.
