TV Goldstar was struck by lightning

Coming Goldstar TV consumers die totally because there is lightning strikes in the tree near the house. after knowing the cause of the estimated part of the damaged power supply. tv i open and see no burned components and fuse break up.First check the power supplay.Tv turn on the output voltage no power supply. check the circuit and check the voltage after the diode turns out the voltage, traced into the input component is there but ouput STR no voltage, before replace STR check all components Power supply. all components baik.langkah next change STR. after change STR Tv I turn it on.tv still do not want to live just Led indicator flashed dead. Must have protec any components that die again pasti.cek voltage B + and others it drops, Protec circuit I loose, then try turn on the tv, byarr .... lights that I plug in B + flame. (Bolam to check output voltage, if the flame means already indicate there is a voltage out) check the normal B + voltage but the screen is not flashing just dark. check the line ABI to IC, check the components one by one finally find the 5.1 v leaked zener diode. then I replace the Diode. plug Protect line directly try hidupin TV ...., byaar ... finally can plasticity of picture. while checking all
voltages, after all normal voltage, plug the
TV cover and hire deh hehehehhe .....
.Based personal experience.
