My ilive speakers IT188b won't play any sound. I'd like to resolder the main audio board, but where is it?!? I got to the insides and pretty much pressed all the connections and they seem in place. Can you help me find where it is? thanks!

I have my granddaughters IT188B with the same problem -- no audio. I have opened it up (if you don't mess with the transformer there are no dangerous voltages) and verified the 26V, 8V and 5V power supplies. Voltages around the quad audio power amp seem to be correct -- mute signal does the proper thing when the unit turns on and off (off is really only muted!). The voltages around the DIP8 audio amp on the PS/pwr amp PCB (on heatsink) don't make any sense however. Without schematics I'm not sure I can go much further. The audio/video I/O PCB has no circuitry except for the sub-woofer out -- so it's not the problem. Audio IN signals go the the RF PCB and then ?? Somewhere there must be a computer and (electronic) switches that select the various audio inputs. What gets to the output board is running the DIP8 dual audio amp into the rail. I'm not yet setup to do signal tracing/injection. Watch this forum for further results. I have my granddaughters IT188B with the same problem -- no audio.

Mr. Hartsig, did you get any further on this, because I've got the same appliance, same problem (powers up, no output from any input, panel will charge iPod, and play/pause iPod) I got into mine, and like you said, all the inputs arrive at the RF section, and there's some digital circuitry on the rear side of the RF section (otherwise it looks like your typical AM-FM radio from the front). There's one shielded cord from there to the PS/pwr amp PCB (on heatsink). I think I'll feed audio into the amp at that point to check that, and also check for any output from the RF/switching section (hopefully OK, it looks more complicated to t-shoot w/o schematic). There's another comment here about the woofer's vibrations opening bad solder joints, My daughter mentioned that it worked, then maybe got jostled, then was scratchy audio, then was dead when I got it to fix.
