LG 55LS4500 No Picture No sound No standby light
My LG 55LS4500 stopped working and I am looking for some help. The issue first started with the audio going out every once in a while and turning the TV off and on would fix the issue. Now the TV does not turn on. There is no stand by light on the bottom right of the TV. I tried the flash light trick in a dark room and did not see an image on the screen. I took out the backplate and broke out my multimeter. The power unit is supplying the standby 3.5V. Do you think the main board went bad?
Any help or advise would be appreciated.

checking the micom voltage.

Assuming that the clock is fine, this is where the first issue comes up. I get no voltage out of the pin 1. I am assuming there is no way to re-download the software without the TV being on so I guess replacing the main board is the next step, right? Or does anyone think that the power board is the issue?
Это хороший вопрос?

So I checked the voltage as the picture shows and it showed 3.5V

Checking pin 2 and pin 17 does not give me a voltage reading. It gives 0 volts so does that mean the power board is the reason why the TV is not turning on?
