Screen goes bank after 2 seconds even if powder light is on

We purchased a 19" PC Monitors 13 months ago. Even if the monitor power light is on, the screen goes blank. If you then switch the monitor off and then on again, the screen comes up but only for about 2 seconds, then goes blank again even with the power light still on. PLEASE HELP!! Best regards Estelle

I just finished repairing a 20 inch acer monitor that had the same issue.... you have to take it apart and examine the power supply side of the monitor. there are capacitors that go bad on that board. you can tell be feeling the tops of them... the feel rounded. replace the capacitors and put it back together and it will work fine

  • All capacitors on the power side looks to be fine. None of them is swollen or burst

pandres, Your monitor will need troubleshooting to find out reason why the 2 "cold-cathode-fluorescent-lamps" fail to remain lighted. They provide "white light" so you can see what is on the lcd panel. Connect a "known good" monitor to your pc to prove monitor is bad. If pc is ok, then your monitor will need repair. This type problem not new and is very common for all brands of ccfl back-lit lcd monitors. Watch some video clips at YOUTUBE that show disassembly and repair of ccfl lcd monitors.

If the power light does not turn color and stay's green on startup, it is not a power problem. It is most likely the inverter. If the unit is in warranty, send it out ASAP. Contact HP customer care by email and have the issue logged in.
If in warranty, they will send you a box by FedX second day and have repaired.
This is a 19" monitor and will not be worth paying for repairs if not in warranty.

Screen Goes Blank


Ive seen this on other monitors. Look for a 1 and 2. Some monitors do NOT auto detect a signal, and this one might not. Look for a way to set the monitor from Digital input to VGA input. Try that and see.

Monitor goes black for a few seconds


Try swapping the monitor cable from the working monitor to the other video connection on your computer. Effectively reversing the connections to isolate whether your problem is the video card in your computer or the monitor itself. If you find the working monitor displaying similar symptoms, then check your video drivers and ensure that you have all power saving features, screen savers, etc... turned off.

Planar PE191M monitor display will not stay on


iv come across this before sometimes people can see that the monitor is actually working but the light has gone out id say bad capacitors that are breaking down. if you want to DIY it take it apart and find the light pcb usually built on the power supply pcb and look for bulging or swolen capacitors this happens alot in my opinion. if you can DIY it get the same caps or same value but better ones. I might be wrong but worth a look

Bank Monitor problems


Unplug the cable from your PC, if the monitor shows a test image, the monitor is fine and the problem is with your graphic card. If you dont see nothing on-screen after unpluging the cable from the PC, then the monitor in damaged. Send it to repair.

Monitor problem: screen goes black, then comes in scrambled


It sounds like this one needs component-level troubleshooting, probably in the power supply section. One or more backlights may be going out, too.
