Re: Troubleshooting Harman Kardon TS-14 Subwoofer

So got some things to gear up for the attempted fix. Bought a Hakko FX-888 and well what are supposed to be rubycons (can any of you spot fakes?). However I think I had a fail in the caps department, the temp is only rated 85C while the OEM are 105C. Maybe not a big deal, but the OEM are noticeably larger....

Re: Troubleshooting Harman Kardon TS-14 Subwoofer

Thanx guys, I think I have narrowed it down to that Weller WLC 100 and the Goot PX-201. I'd go with the Weller WESD51 If I was working (been holding out to see if this one i got on a line goes through). But yea as far as the DMM, I so want a Fluke. Been checking Craigslist and ebay, but hold their value quite well. Ive used them (company supplied) and they are awesome. Funny you mentioned the under $20 category. I bought some POS from Marcs for like 4 bucks just to check really low voltages. One day i felt the need to check an 110v...

Re: Troubleshooting Harman Kardon TS-14 Subwoofer

Good point Longbow. I have been checking out some amplifier circuits on buildingGadgets.com, and figure I want to get into it as a hobby. As I play guitar, and wouldn't mind being able to tweak some things here and there or make a little amp. I'm looking at irons, have been going through the Test Equipment Usage, Techniques, and Reviews and gonna make a decision soon, very soon. Not gonna buy a cheapie, but can't go high end. No Bass = Bad

Re: Troubleshooting Harman Kardon TS-14 Subwoofer

Thanks for the push Longbow, I usually do surprise myself when I tackle something. I have a habit of talking myself out of things, but once I get into them, turns out they aren't as bad as I perceive them to be. I did take go to a vocational Industrial Electrical Maintenance program, that lightly touched on solid state electronics. However not as in depth as I would have hoped it to been. Looking at this makes me want to go to an actually electronics program. Here are some picks of the rest of the boards. Does they look like quality...

Re: Troubleshooting Harman Kardon TS-14 Subwoofer

I was gonna take it to the local electronics guy, but appears he isn't open anymore or moved. Looking at irons ( don't have any tools) and replacement caps right now. I'm gonna take the boards apart and post some more pics tomorrow.

Re: Troubleshooting Harman Kardon TS-14 Subwoofer

Cool, working on the bigger picture. I was disappointed myself when I clicked on it.

Found this cool site while looking for some answers on my sub. Started off intermittent, switching it on and after a minute of thumpage, going into standby. Now when I switch it on, it is trying to turn on but it cycles back into standby, continually. I took it apart and damage wise it looks to be this. Apparently it overheated and melted the coating, but am somewhat newbage and am unable to figure out what the specs are to this, resistor?...
