My monitor (HP w2207h) turns on for 3 seconds then goes black?

Question

My desktop monitor keeps going off. If I unplug it and plug it back in, it will stay on for 3 seconds and then the back light will shut off. I tried connecting the monitor to my laptop and have the same issue. If I open up the monitor menu it does the same thing. I see the menu for 3 seconds then the back light goes off again. Any ideas?

Answer 1

Do you have the latest version of the monitor/display driver?You might want to try to reinstall the drivers of your monitor.



Is the plug defective?Try to lower the resolution,It might be happening because of higher resolution..Also get all the latest drivers for your pc from hp website..



If none of the above trouble shooting steps work,Contact HP online technical (chat) support.They will help you trouble shoot your problem.

Answer 2

I have the same problem.



Perform the following check - shine a flashlight onto the screen. Can you see a very faint image being displayed. If you can you have a backlight issue. You can actually select and see the OSD (On-screen Display) menu. Unfortunately selecting the factory reset option won't fix the issue. One possible cause is the power regulating circuitry. Sometimes lowering the brightness from the factory default of 90 can resolve this issue but it will work only if the regulation issue is related to the voltage level. Most times it is not.



I took my monitor apart and pulled out the power board. Usually for these types of problems it is a heat sinking issue with the power rectifier ICs which the fix is to replace the non-conductive thermal paste. Unfortunately in this case that did not fix the problem. I need a circuit schematic to go further but I am a bit pressed for time and I may just send the monitor in for recycling.



Note 1: You can still talk to the monitor via the HP Display software "HP My Display" by the way if it is a back lighting issue and the image is still displayed on-screen.. Doing a factory reset on the monitor either from the HP display management software is the same as doing it from the monitor's OSD won't fix the issue.

Note 2: It doesn't matter which video input you use - Analog or the Digital Video input.

Note 3: Hardware problems are typical outside the scope of HP's support site. As is the user guide. Pretty much most product support sites give you two solutions to a problem 1)update the driver for the device or 2)performing a factory reset on the device. Sometimes there is a third, where by holding down a button or two with either power on or off for 15 to 60 seconds one can perform a hard reset on the device, but usually you have to find that out on a support forum.

This doesn't sound good. Either the monitor needs to be repaired or replaced, or possibly (if you're lucky), there is something wrong with the video connector. Look at the connector to see if any pins are missing or bent. Check out the back of your computer(s) to see if there are any pins lodged in the input holes. This is a longshot but worth checking out.



The two links below are 1) troubleshooting the monitor and 2) forum reporting this "blackout" problem and some of the peoples' experiences. Note that there isn't a resolution in the forum, but the lesson learned that I take away from reading it is that if your monitor is still under warranty, take it back right away to exchange it or get a refund.



Good luck!

Answer 4

Is the monitor actually shutting off or just going into standby (what is its power light doing when on or it goes blank)?



If just going into standby, it could be a cable or connector issue. If it actually shuts off, there may be an internal problem with the monitor.

Answer 5

The PC may be in sleep mode and is failing to properly "wake up" or the display or video card may have gone bad. Since you state it is showing a red glow for a moment, it would appear to be the video card or PC to be at fault.

Answer 6

something is dead
