  • First remove the stand.

  • Remove the bezel. This can be done by hand and a plastic knife. Approaching the screen from behind, peel the bezel with your fingers (photo).

  • When removing the bezel, be careful with the control panel (stuck in place with glue, covered with glued-on strip) and power-button (2 screws).

  • To solve power on problems, inspect the board. In my case there was a cold solder joint that actually showed a little spark when plugged in (photo Q816). Re-soldering fixed it.

  • Be extremely careful fixing these switching power supplies, even more so in Europe where one has 230V. Discharge capacitors etc.
