I use my HP V72 monitor for my photography. It powers on but there is no picture....I tried unplugging it and replugging. It just keeps making an off and on clicking noise. The green power light flashes and than stays on. When I move my mouse it makes the sound that it may appear...but does not. I tried my flat screen monitor and it works just fine. Did my HP V72 suddenly just die?

Thanks for any help on this~

and are probably right that the panel has failed, but a few quick checks can narrow the fault before deciding on replacement or repair.

Try these in order:

  • Confirm the monitor's own menu/OSD appears when you press its menu button. If the menu is visible (even very faint), the video path is fine and the backlight/inverter is the likely culprit.
  • Do the "flashlight test": in a dark room, shine a bright flashlight at the screen from a steep angle. Look closely for a faint desktop image. If you can see one, the LCD is showing signal but the backlight is dead.
  • Swap cables and inputs (VGA/DVI) and try a different known-good video cable. Since a second monitor worked on the same PC, the GPU is probably OK, so focus on the monitor.
  • Listen to the clicking: repeated click-click usually means the power/inverter board is trying to start and then shutting down (common with failed capacitors, a bad inverter board, or a failing lamp). Visual inspection for bulging or leaking capacitors on the power/inverter board can confirm this, but only after unplugging.

Safety and next steps: disconnect power before opening the case. LCD backlight inverters and capacitors can store lethal voltages; if unsure, have a shop inspect it. If the OSD never appears and there is no faint image, the main power or logic board may be dead and repair costs can exceed buying a replacement, especially for older models. If the backlight/inverter is the issue, a local repair shop can often replace the inverter lamps or capacitors at modest cost.

Sounds like that to me. What do others think?
