ty for your replies, I'm thinking humidity did this, since it was a stored working unit, it was stored for at least 6 monts, then i sold my main 5.1 hometheater, so i was going to use this z906 to replace it, but when i was going to use it, it blew, I opened it and it has alot of humidity on it, i cleaned it with thinner but i think it wont turn on without that capacitor (c45) that blew, i wanna replace that c45 and see if i can make it work, but i dont know what is the value of that capacitor, as i dont have a spare psu to mesure it, what you think i can do? can it be the 1-12 uf ceramic 50v capacitor as someone told me? but wich one? i wanna give it a try. ty in advance
