All the fuses are good, amplifier is 3 years old. I have no pets, took off the cover and is very clean inside. It is a jolida jd1501p, it seems to boot up normal, not in protect mode. Has zero output, nothing even when ear up to speaker. When turned on goes from flashing red to solid blue as normal. Might be missing a relay click when blue light appears, not really sure about that though. Thanks for help...
