Double check the voltage selector and see what it is set at. If it is okay then your amp may have a short circuit somewhere in the power line of the main board. You will have to disassemble it and see if you can visually identify components that look damaged or missing. Post some good images of your board as well as the location of the fuse etc. with your question. Adding images to an existing question
