The missing resistor is not the problem. If the red led on the power board is illuminating faintly only when the micro switch is pressed, your music sensor circuit is not activated, assuming you have the speaker wires connected to the music sensor terminal block connector with music playing? I would check both voltage outputs of your transformer on the secondary side before going any further. Here's a schematic of a ML power board to give you an idea of how the system operates.

I'm sorry, now I know what you mean,my english is very poor:ROFL:
 
Still do not have blue light. The blue logo is flashing about 3 seconds When The speakers connect to power and after 3 seconds are just dark. I'll send this power boards to ML think...
 
Just got the power boards from ML . Problem solved. Thanks for help...:music:
