Hi all, I have a Pioneer QX-747A that has no sound (everything else seems to work, lights, tuner and so on) but the relay does not engage/click, so I dropped it off to a local tech to have it checked out (paid him in advance to look at it) and he would tell me what's wrong with it. Initially he said it would take a few days to get to it, but to my surprise he called the next day and told me that there is a short somewhere and I would have to replace all capacitors and it would be a $300-400 job. When I pressed further he said that he was able to get one channel working and had disconnected the other ones, when I asked him which one he said he didn't remember and that was that. Now call me paranoid, but if he was able to get sound out of one channel wouldn't that isolate the short? Any thoughts? Should I take it to another tech for a second opinion or let it go at this point?
