Hi guys... need a little help here.. costumer brought me this Skyworth 40E360 LCD TV.. symptoms.. no backlight no response to RC and manual switch , the moment it is connected to the wall outlet the indicator lights green.
what i've done.
check the voltage in the secondary..shown in the attached picture.
i manage to locate defective capacitor 1000uf/35v.. meter shows the cap value is way below measuring only with 50uf and esr of 150 ohms.. i replaced that but with no avail..
check the backlight led system with backlight tester.. all led lit
checked all the components, mosfet diode resistors inductors, photo isolator..
in the primary and secondary circuit with no avail..
do i need to reflash the eeprom. problem is i dont know where the heck it is..
can someone guide me.. im lost
