Because of the storage capacitor C818 before an inductor L803, when the supply voltage is 13.5V AC component slightly, energy storage capacitor will produce a higher voltage (greater than 13.5V), so due to the energy storage capacitor voltage is not high enough, only 20V , it is easy to burn himself in the repair process, encounter a few examples of the storage capacitor burning:.. 1.DSC-F707 can not boot .2 DCS-F717.LCD screen no display solution: remove the storage capacitor, or replace the higher breakdown voltage capacitor (capacity unchanged)jyyservice manual download site
