It recently started acting up. The symptoms come randomly and usually go away after unplugging it form power for a short while and then plugging it back in. The symptoms include:

  • Short blackscreens
  • Permanent blackscreens unil I power cycle (power LED stays green)
  • Unresponsive buttons (including power)
  • OSD Displaying (with unresponsive buttons)
  • (once) the screen turned all white

As it is now 11-12 years old, I am suspecting that some capacitors have gone bad and would like to look at them/replace them. However, I cannot figure out how to open this specific monitor. For most monitors it is easy to spot the line where the plastic clips hide, but I am unable here.

I Suspect that the clips hide somewhere around the green or orange lines (next image). However, I cannot fit anything in there.

Does anyone have experience with disassembling such a monitor/can give me any hints? (Also tell me if you think the issue aren't the capacitors)
