Hi, welcome to the forum.

Can you give a few more details? How does it shut down? Do you get a clicking sound? Does the LED stay on? Both channels the same?

You may have a short to ground at the outputs. That would be the first place to check.

Could be a fault in the input circuits.

Remove the input track grounding and give it a try. Be sure that you do have a ground from the RCA to the board somewhere, though or you'll be in for loud surprise!
