    Same here, around the same date. Interesting.
    Picture is shown for about two seconds, then the backlight turns off with a faint buzzing sound. Pressing the "source" button multiple times lets one glimpse the actual screen content again for two seconds. Only the backlight is off; if you look closely you can see the screen content even without backlight. I guess the backlight power supply or inverter failed but the actual backlight is still okay.

The backlight power supply in the H950 series suffers from a manufacturing defect. Hansol might replace the unit even if it's not covered by warranty anymore. Contact them.

Otherwise (and if you have electronics skills), replace the electrolytic caps in the monitor's power supply. Take proper high voltage precautions!

  • Disconnect mains
  • Wait at least one day for caps to discharge a bit
  • Remove monitor stand (four screws)
  • Put the monitor face-down on the table, plugs facing to you
  • Remove back cover (snap-in, difficult to open without minor damage) - be cautious: front buttons are connected using a rather short cable, do NOT try to remove front cover
  • Remove EMV casing screws (four screws) and ground wire
  • Disconnect CCFL tubes (four connectors), noting connector orientation
  • Disconnect front buttons pcb
  • Lift EMV casing side facing to you
  • Disconnect power supply board (left) from signal board
  • Unscrew/remove power supply board - caution: C12 is likely to store mains voltage even after days!
  • Replace caps (C34 and C66 are likely failure candidates for IPHS19-S rev1.2 boards; you might also replace C31, C32, and C35 while you are at it) - higher voltage and temperature rating are okay, capacity has to match
  • Assemble everything again

I have power but a black screen


Your backlight has lost power, even though the LED says there is,

This problem can be fixed, but the expertise required is costly, and really not worth the work (that is why it is costly)

Best bet, dispose of it responsibly, and buy a new monitor, or a still working used one. The former will be almost the same cost as a repair, while the latter will be cheaper.

Of course, if it is still under warranty, then RMA that ******.

Some of those monitors have had a problem where the large HDMI cable attaches to the back of the monitor. Try inserting the HDMI cable then instead of tightening the screw supports power up the monitor and wiggle it slightly if the monitor works then the problem is in the connector and may need to be resolderd on the inside. have you tried using another HDMI cable to rule out that the cable itself isnt defective?

Most likely the power supply, or the back-plane lamps, or the back-plane supply, or a defect on one of the processor boards is loading the supply too much, or any combinations of these are defective. You will have to have a source to try the boards to fix the monitor. I would suggest to find the authorized service rep for your monitor. They will have to service it for you. If the monitor is out of warranty, the fix will not be cheap!
