Title: Re: Blown Cap Post by: stayouttadabunker on October 01, 2011, 08:39:21 PM The blown capacitor is at location C59 on the board.
What is the model & Version # of your board? I may be able to find some board schematics that will help into pinpointing exactly what goes there. OR Some member can take a look at their good board and tell us the numbers labeled on the component? Title: Re: Blown Cap Post by: Buzz on October 01, 2011, 08:59:35 PM Looks like a 3902 board.
Title: Re: Blown Cap Post by: cowboygames on October 01, 2011, 10:08:05 PM I should add that to blow a cap up in that manner would indicate a short in the circuit, you may have more than just a cap problem. AC voltage will take a cap out that way pretty quick also.

Title: Re: Blown Cap Post by: poppo on October 02, 2011, 08:59:45 PM If the hum is the only problem, you can probably just try different values as it's probably not that critical to be exactly the same. You can easily solder a non-surface mount cap on there. Radio Shack sells a 'grab bag' of caps for a few bucks. Title: Re: Blown Cap Post by: Tilt on October 02, 2011, 10:32:30 PM It's a filter cap on the input side of a +5vdc regulator for the audio. I had one fry on one of mine once too. The manual specifies a 16v part, but 25v would probably be better. Mouser.com p/n for a 16v replacement is: 80-T499B475K16TE6K0.
The parts diagram calls it out as : C59,69 CAPACITOR, 4.7UF, 10%, 16V, TANT, 3528, T/R Here's a page from the 3902 schematics. The cap is circled in red. Hope it helps. Title: Re: Blown Cap Post by: poppo on October 02, 2011, 10:39:27 PM That's a very common value. Again, something RS should have. It doesn't have to be surface mount, and why pay shipping for a $1 part.
Title: Re: Blown Cap Post by: zarobhr on October 02, 2011, 10:40:27 PM thanks for the info
Title: Re: Blown Cap Post by: channelmaniac on October 03, 2011, 01:43:17 AM It's pretty common for those caps to short out and burn... just like the drop shaped tantalum caps with the 2 wires soldered in...
