First of all, Marcus, you will need to check if you have blown off the speakers. Just remove and use a good 1.5 AA cell to test both the speakers. If ok connect and switch on. try to hear if the relay is clicking or if you hear any noise. If not disconnect, open the set and use a multimeter to check if the output had failed. Check on the sections only if your are familiar working with circuits or else it might not be recommended. Get help from a friend to check the protect circuitt and the main board for failure of the mosfets/ outputdrives. If you can reset the amp do so by keeping the menu pressed on swithed on. or keep it off for anout 12 hours. it will reset on its own. I hope this helps. Good day
