HP f2105 Monitor problem

Hi all,

This is a general cry for help concerning my one-year-old HP f2105 monitor. Nice-looking thing, works fine when it's on... and that's just the problem.

The monitor will suddenly shut itself off ("Monitor going to sleep" ) sporadically, and is completely unresponsive to any external stimulus
such as moving the mouse around, pressing a few keys on the keyboard, moving the mouse around frantically, slamming keys on the keyboard, etc.

The only thing that works, other than just restarting the computer, is pressing the sleep button on my keyboard, and then waking the computer up by pressing the same button again. Even doing that, there's no telling when the monitor might suddenly shut itself off again.

I've avoided the problem up till now because I haven't been using my computer for long stretches of time, but I no longer want to be a prisoner to my monitor!

Has anyone had the same problem? Might it have anything to do with a video card conflict? I have an ATI Radeon 9700. Running Windows XP SP2.

Thanks for any response (even viewing this would be nice - in case any of you ever run into people who have this monitor and this problem). HP's email support is nonexistent, by the way.

I just found your post and wanted to say that we are having the same problems, and have been for about 2 weeks. I at first thought it was a driver issue, because the video card driver had been updated around that same time. I unstalled and reinstalled a slightly different video driver version, and alas, next day, the same problem. Monitor appears to be powered on, but has black screen. Computer is fine, and can be accessed remotely. You can sometimes access remotely, reset the video resolution (giving it a swift kick in the butt as I call it), and then the image will return to the screen. If you power off/on the monitor, you will see an image briefly, and then it goes away.

I have messed with video card drivers (NVidia GE Force 7300), driver settings, refresh, resolution, power settings, etc., all to no avail. I replaced the monitor with another monitor, and it came right up, then plugged back in the HPf2105, and it went came on and the right off again. This all leads me to believe its monitor issues, or monitor/card communication issues.

If anyone else has this issue, or has any other feedback, please post as its always a help.

I have bought an hp f2105 with a broken inverter they said..(Bought it for 10 euro.)

Last week i have recieved part 48.L1S04.A01MSS inverter for the HP F2105
http://www.lcdparts.net/DesktopInv [...] S04.A01MSS
But it didnt fixed the problem fully.

Now when i start my pc the monitor flashes for a half of a second hearing a high freq/sound
I see the bios startupscreen /windowslogo/welcome when resolution chances.)

powerbutton''blue light'' stays on and goes off after a few minutes to standby''yellow light''
Is this a normal behaviour??Am i doing somthing wrong?

Can it be a hardwarefailure? (backlight)
(Or is there a way to wake it up again plugged in as second monitor?

Sorry for my poor english

Wondering if your solution has stuck. I have the same problem and activating dual screens did not help. This started a few weeks ago with sporadic problems going to sleep. Restarts would sometime get it to act normal. Now, it just stays asleep. Even goes to sleep when no computer is attached, the "no signal" screen comes on for a second then to sleep. I have had the monitor for 2 and a half years without problem. Luckily I have an extend waranty from SAMS Club because I don't trust HPs.

Desktop Monitor Inverter
The defective inverter will cause the following symptoms:
No Display or Dim screen
Screen Flash on and Off between 1/2 to a few seconds, but power indicate light stays on solid green.

Ten steps instruction.

Ok I have this same monitor and had this same problem (note the HAD). I was able to fix the monitor without opening up the case (I did open it up but didnt do anything on the inside). First try to induce an OSD lockout. You can do this by following the steps on this website to get into an OSD locked monitor, the steps do the opposite when the monitor is not locked causing a lockout http://www.thefakegeek.com/2009/04 [...] t-problem/ . Fix 2 worked for me because I was able to get the monitor to not go to sleep by unplugging it from the computer. Once you are in OSD you can try a factory reset. That was not what fixed it for me but it should be tried first. Next (a computer will need to be hooked up and running for this step) go into management or something (I dont have the monitor in front of me so i forget which option it was) and find where to switch the sources and switch it to DVI or VGA depending on what you have your computer hooked up to it with. If it still does not turn on hook up another monitor to your computer (assuming you have two inputs) and set the monitors settings manually. I am using linux with Nvidia grpahics cards and use nvidia-settings to set the monitors geometry and stuff but I bet it could work with any operating system.

p.s. I know this method sounds crazy but my monitor has been running for several hours now with no problems. I also dont think the auto source selection mode will ever work correctly again because I think it may be the source of the problem.
