Find a number on that chip and we'll talk I say it's not worth it. If the engine compartment in my car caught fire and I put it out... I wouldnt just repaint the hood and keep driving it around. Something is wrong with the device, and unless you can isolate what made it burn out, or derive it from what function the chip performed, you basically have a battery powered fire hazard hanging around, even if you swapped the chip.
Buy a cheap speaker set from walmart at 1/4 the price, then hack it's plugs to work with your device of choice instead.
