Where can I obtain service manual for the Dell A525 computer speakers as I probably have a dry solder joint problem. Require circuit diagram with component layout on PCB. Roger Alban [email protected]

Most likely the amplifier that drives it all is in the speakers, not the sub.

Yes, i have a brand new set of DELL A525 Speakers, reply to this solution on FIXYA (ie say you want them) and i will put them on EBay for you to purchase on a (buy it now) so you you can have them straight away, £10 + P&P £2.70 or give me your email on here and we can sort it out that way. (set up a disposable email address or you may get spammed)

You can't get an original part unless you find a system on eBay or somewhere similar and take the part from it. Computer companies buy these speaker systems from other manufacturers, and treat them as just one big part. Under warranty they simply replace the entire unit. No components are offered (other than the wall-wart AC adapters when used). I went through this with Compaq/HP and Dell when I worked in service for a big retailer. Most people just buy a new system when theirs goes bad out of warranty.

Now, if you're like me (and I know you are since you're asking), you don't like to throw anything away if it can be fixed. Since this is the subwoofer, it's probably going to be on the floor or otherwise out of sight. So another possible repair is to get a replacement control with the same value as the original, solder some leads onto it, tack them to the pcb pads of the original, and just let the replacement hang out the hole where the original came through. Or you can be a little more ambitious and mount the new control properly, then wire it to the pcb.

Good luck in the repair, and thanks for using Fixya!

If everything is turned on and the speakers have current getting to them, there is no quick fix, you just got a pair of speakers from a bad batch which were weaker than the rest and are now defective, if I seen it once, i've seen it a million times. Nowadays with chain production, you get a few batches that were on the end of the soldering bath's contents and get less solder on them than the rest which cause premature failures and faulty solder.

hi all,

try replacing the output intergrated circuit
it is inside in the bass box possible it has been blow off
