SOURCE: I have sony TA-V715 amplifier,
The possibility is that one of your premap input is not working and the fault could be in the preamp input section. Possible that the input IC, the selector digital IC or the tone amp could be faulty. It will be easier to find as one section is working and you can cross check with voltage readings from teh working side. Also apply the audio test from the output to confirmt he section, replace from the working side to confirm the fault. I hope you have checked on the speakers/ ouputs by crossing.Also check for fuse or failure of the output section. Hope you try and confirm.Good day .
