    Sony XBR-65X850E not powering on or showing picture on screen

    I have a Sony XBR-65X850E that seems to not want to do anything. It does not power on or show any picture. The power board checks out and works. Pictures are attached of the tv.

    What does it really mean the power board check out and work?
    Does it the power board gets all the control Voltage and puts out all the Voltages?
    You need to report the Voltage readings of the power board connector that goes to the main board, you MUST PUT DOWN PIN NAME AND FOLLOW BY THE VOLTAGE READING FOR EACH PIN, that will be the starting point.
    We also need good clear high res pictures of the whole top side of the power board, the picture you provide is not clear enough to read anything on the board. The picture you post looks like to be from the web with low res.

      Here are the pictures of the power board.

      Pin 4 is putting out 2.6v

      Pin 7, 8, 9 are putting out 12.6v

      All the rest are showing 0v.

        Connector CN6401 has pin label for each pin so you MUST put down the pin number/name and follow by the Voltage reading for each pin.
        There are 24 pins (it has ODD and EVEN pin columns) total so are you sure you are do not even have STBY3.3V on pin 5?
        Make sure you count the pin correctly.
