Apex Tv No Power




This apex tv has no power. So i open the back cover and i saw the fuse is open and it has dark color inside the fuse that means there is a short component in power supply. This tv has dvd combo. First i checked the diode and i found it okay and all the active components in power supply area. To my surprise i didn't notice first that the main filter capacitor which is 220uf 250volts was blown. There is a leaked with an orange color that looks like a glued around on one side of that capacitor. And when i cheked it, it was shorted.Since i cannot buy the same value of capacitor, so i decided to replaced it with 270uf 400volts and the tv works perfectly.But if possible always replaced with the same specification of capacitor.
