	[title] Fixing the problem
	[* icon_caution] *Caution: *The circuit board contains capacitors (they look like cylinders) that can shock you if they discharge. Be careful not to touch them as you work. If possible, use a [guide\|2177\|capacitor discharge probe\|new_window=true] to safely rid the capacitors of dangerous charges.
	[* black] 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. Your case might be harder to find and fix.
+	[* black] Many repair guides talk about replacing all capacitors rather aimlessly. In this monitor they used Nichico caps which are very reliable. So that is an unlikely fix.
	[* black] Be extremely careful fixing these switching power supplies, even more so in Europe where one has 230V. Discharge capacitors etc.
