I have an old onkyo receiver that keeps cutting off the sound for a second then comes back on? once it starts doing it it gets worse. do you work on these? ive never had a problem with it until now. any quick ideas? how much might it cost?

Onkyo stereo after factory reset I unplugged power on accident and now usb ports don't work no sound no net. Do you fix and update firmware on these???

They definitely repair and refurbish recievers, older ones included. You should probably give them a call to see how much they would charge.
