AMP2 - No LED light - blown up??

Hello everyone,

 

I used an AMP2 on a RP3B+. Last week I switched to RP4 + max2play. Configuration of amp2 shold be fine in the /boot/config.txt.

Power supply is the same as before with 12V and 5A. But I don´t have a flashing light on the AMP. I can not remember: Is there just one LED after configuration as with the DAC+ or is there a general power LED mounted? PI is working fine with both LED´s (red/green)

How can I figure out if there is something wrong and wether I can so something on it.

Thanks in advance,

Thomas
