No Video or Audio
Hello, I have a Vizio LCD TV that I found near the trash can at my building. When I try to turn the TV on nothing comes on except for the LED power indicator and then it fades out after a few seconds (which I learned much later that is normal for this tv). But I bought a used power board and then a used video board and nothing changed with the TV.
I am thinking that there is a video board problem. I am considering buying another video board.
Shouldn’t I get something on the screen after replacing the video board? Is the problem definitely within the video board?
This is how the TV looks on the inside.
Is dit een goede vraag?

djchitown do you at any point get any audio? Have you measure the voltages coming from the power board to the main board? Besides changing the boards, what have you checked?

I don't hear any audio. I am not sure if the TV plays any audio on power on. I don't know how to use a voltage meter and not sure how much voltage is supposed to come of certain cables.
