Hello colleagues I confess that I have no experience in audio equipment. I will explain is a mini-component samsung model MAX-A55U. It turns on normal but has no audio. PCB or chassis AH41-0116A. It has completely burned 1 capacitor FC9 is electrolytic and capacitor AAC18 is ac. I changed the resistance and the damaged filters and I still don't have audio. The heat sink that goes with the ic tda8920bj gets very hot at low volume. I thank you very much
