John, I looked at the link you posted. I have a steam engine LC+ and it appears my board looks different and certainly better assembled. But, I have no idea what "board" you discuss and what "chip".  Here's a pic of the area I think these components are located, but any help would be appreciated.   I'm pointing to what I think is the "sound board" and is the "amplifier chip" the component t the left and above my pointer????

Which board and source?

Which chip and source?

Thanks.

Sorry Ed,

Been buried under my Camry doing a nightmarish job for several days.  It appears John already answered you.

As John described.  Cut the legs off the chip (don't try to unsolder it to remove it).  Then heat the pads and lift off or sweep off the little leg bits that are left on them.  A tiny amount of solder on the pads is all that is needed (you can always add more).  Tack the two opposite corners of the new chip to hold it in place, then solder on the other ones.  Don't apply heat for too long.  There should be enough solder left over from the old one to tack the new one in place.  Then add a tiny bit more as needed.  Watch the orientation.  The PCB is clearly marked and so is the chip.
