Before putting your speaker back together I recommend testing it to make sure the fix worked.

Also, if you feel like the power and other indicator lights are too bright, now is a good chance to gently bend the legs of the led's upward to diffuse the light.

One final note. I did notice that disconnecting and reseating the two cables connected to the speaker grill while the speaker is powered on will sometimes get the leds to start working. I hope this helps someone.
