    • Before you begin, be sure to unplug the device from the outlet.

    • WARNING: There are capacitors inside that can pose a serious shock hazard. Be very careful not to touch any exposed leads on the power board.

    • First of all, you need to unscrew the 4 screws holding the stand. After that the 4 screws holding the back panel, they are located in the corners of the device (only the top ones are shown in the picture).

    • Second, you need to pry the plastic grey basel on the front of the monitor. There are several clips holding everything together.

    • Also after removing the basel it might be a good idea to give the screen a good clean.

    • First of all, disconnect all the connectors (5 marked with arrows.)

    • Second, remove the 4 acrews holding the bracket, marked with blue. (Also there might be some aluminum tape holding the covers, just rip it off, you wont need it for reassembly)

    • Third, remove the 4 screws covering the boards, marked with red.

    • After opening the cover, remove the 4 screws holding the power board and check for busted capacitors. (You might need to disconnect the connector, it might be easier for you to work)

    • In my case I had to change the 7 capacitors marked in red (the picture is after the change).

    • You can always put higher voltage (V) rated capacitors (if you have the space), but dont change the farad (F) rating.

    • Remove the 3 screws holding the main board and disconnect the 2 connectors

    • Unscrew the monitor connector stands so you can remove the board.

    • Flip the board and inspect the capacitors. In my case they were all fine (except the one marked in blue) and the monitor was working after I changed the capacitors on the power board, but yours may be different.

    • After putting everything back together, the monitor was working once again. I tested both display ports and the AUX port.

    • If fixing the capacitors didnt resolve your problem, please leave a comment.
