HPW2338h monitor turns black, but power remains on

[Andyster]

I've been using a HPW2338 LCD 23' monitor for about 2 years. But recently, the screen flickers on for a second on startup, but turns black in a second, but the power LED switch remains blue. When I shut off the monitor, and turn it back on, it flickers onto the screen again, but the screen turns blank almost immediately after, and nothing can be done. I've tried exchanging cords, switching ports (HDMI, VGA), and even changing computers and power source, but the problem still remains. Does anyone know how to fix this?

Does the screen display anything at all, or is it blank the whole time? Also, does the screen display any kind of message?

The whole thing might just be dead. However, if there is a message or anything at all when you first turn it on then it could be a software problem. If you have integrated graphics and another graphics card, it could be a setting in the BIOS.

I'll figure out as much as I can about this, but I need to know more about the graphics/display hardware you have.

Thanks for the reply. There is no message, it is just black. I read up on some other forums, and others said it might be a dead inverter? Because there is also this foul smell coming from the monitor itself. My graphics card are okay, and I'm pretty sure there's nothing wrong with the BIOS, because other monitors work fine on the same computer.

I'm having the same problem with my w2007. The only difference is I can turn the monitor on and off and for a few seconds it will display whatever is on the screen. i.e. login in window. I've switch monitors and everything works correctly. If I quickly press any button  on the monitor  (menu, -, +, Auto) after power it on and off for a brief second it will say monitor going to sleep.

Is there a reset button or a way to reset monitor?

If the monitor goes on and off, it could be the capacitors on the power board, but if the monitor is on but the screen is goes black, then it could be the capacitors on the video board.
