Hi!
I got a powersupply board from my LG oled55c7v. I dont got any warranty or anything. I found it at my local recycling station. When I press to start the TV it lights up for 1/4 second and shuts of. I suspected the powersupply. I tried to plug in the powersupply itself and test the voltages coming from the headers where the pins are. But when its plugged in I get zero voltage from all pins, some pins suppose to have 12 volts and some 24 but every pin is on 0 volts (A few are on like 0.07 volts)
here are pictures of the powersupply board: https://imgur.com/a/nCdc1av
The PCBs name is: eax67149611 (could not find any schematics)
You guys got any idea what the problem could be? and what I should do to find the faulty component(s) ?g
Note that I am new to electronics and but very interested in it and fixing stuff myself. I know a few basic components like capacitors, resistors, transistors etc but not all. So If u mention a component please tell me what it is in category
