Hi Derek, I have the same problem as yourself and it would seem the capacitors on the power board require replacing. Have you managed to open up your monitor yet? I have removed the stand, also the two screws at the bottom of rear panel and tried to open it by inserting a blade into the four slots on the lower edge but the rear cover will not budge. Would appreciate to know how you got inside it and if you got it fixed yet. Cheers.
