how to see what the problem might be?

I have a music maker shield (with the amplifier). Had it working wonderfully for a couple of days. Moved back to the bench to work on some things and it didn't play when I plugged it in. The console shows the simple "Couldn't find VS1053, do you have the right pins defined?". I uploaded the sample sketch again (making sure the Shield object is selected and not the breakout one) and I get the same behavior.

I can use a multimeter and tell the shield has power, and I here a normal "click" from the speakers when I press reset. But otherwise, I can't think of anything I can do next for troubleshooting. I don't have a scope.

I've gone along and tested for any obvious bridging on the soldering, and I didn't turn up any. Since it was working in this exact config, I don't think I have a sketch issue. I'm more worried I've done something else to it.

Any suggestions for how to see what the problem might be?
Please help.

I didn't find the right solution from the internet.
