I shipped a restored Zenith 10S147 Chairside to Denver. Worked perfectly when it left here. The buyer says he gets no sound, and was wondering if there was anybody in the Denver area that could help him. I'm sure he's willing to pay, but if not, I am. Anyone?

Yes sir. I suspect a loose wire, or he didn't turn it on right.

Check that it's plugged in and that the speaker wires are connected.
Both are the last two problems I had here.

He hasn't contacted me yet. But I suddenly did get a lot of spam (like "you want to have a relationship?"). But it could be a coincidence.

He did tell me that he has no Wifi, and he has to go to a friend to borrow his Wifi. That's why it takes so long for him to respond. I didn't tell him that he can send email via a cell phone. I'm wondering if he even has a cell phone. But he seems like a nice guy (this was an ebay sale).

OK Everybody! I fixed it!
So I get there, and I can't find his house. I ask a women walking around, and she finds out where he lives. * I park, and I come in. He shows me it, and I take a look it it. I start tapping on things. I heard some snap cracklesparklepony going on. However there is no sound. (All tubes lit and hot). I take the chassis out of the cabinet, and I start doing measurements. Half an hour later, I come to the conclusion that the last IF transformer is open on both the primary and secondary. I open it up. and I see this:

The form was floating in the can, and the vibrations caused that to break. OK, I solder and tie it in place, and put the radio back together. A screw fell in the chassis, so we shook the radio to get it out. Nada, still stuck. Oh well, we put the knobs on, and whaddayaknow? It doesn't work. So we take it apart, again. 30 minutes later and after opening the IF can again, I diagnose the issue as a cold solder joint.

The wire came right off. We put it back together and success! It works.

One question. What did you use to solder that wire? A candle? :lol:

Good troubleshooting work, Jay. That one took some digging.
