Monitor won't turn on -- flashes on then off again

Hi there,
For the last few days, my monitor has been misbehaving. When it goes into standby mode (after long period of inactivity), or after powering down, it has a very hard time waking up. Pressing the power button will cause it to flash on once (for about a quarter second -- frames do update during this time), and then off again. After flashing off, the power light remains on, but the screen is completely blank. IIn the past, it's done this and I've had to press it a couple times for it to snap out of this mode, but now it seems to be permanent. I've pressed it hundreds of times (on then off then on...) with no luck.

It's definitely a monitor problem, as the problem persists when plugged into other computers. I can't see any color that would suggest just a lamp problem (but couldn't see real well with the flashlight). I tried adjusting the resolution within windows, with no luck.

Any ideas? I'm close to resorting to the dropkick method of repair.

    All good ideas, thanks.

    Unfortunately, I don't think it's a CPU problem. I tried plugging the monitor into my laptop and had the same problem. Heck, it even does the flash when it's saying 'No Signal' (when it's unplugged).

    As for temperature, the only correlation I can make is that as it's gotten colder out (winter time, average temps lower) the monitor has maybe gotten more finicky.

    I appreciate the help, though. Any other thoughts?

    my monitor is a ViewSonic 19" VA915 doing exactly the same thing. i have tried changing the cable, plugging into different computers etc but its always the same problem. happens right from boot, during POST and BIOS screens so its not a driver or windows problem.

    i had to replace the monitor today; a real shame!

This is probably a RAM memory trouble, you have to try with 2 ways: 1) Try with another RAM memory to start your pc, 2) Verify the memory using a DOS software to check it.

Also, you could reset the BIOS using the jumper settings established on the PC Motherboard Manual to try if the BIOS is fail, or update the PC BIOS.

At last, You must check the temperature generated on the devices, if it's warm it means that the Hardware needs to add more fan coolers, or deactivate Overclocking. The overheat cause this fail too.

I have the same problem with my AOC by Envision Peripherals brand LCD monitor. I have discovered several times that it does not function in the mornings, and after closer study I have seen time and time again that it will only turn on after the fireplace has been going and the house has warmed up. Temperature is the issue, but why, I have no idea.

    With what you have said, sounds like a cold solder joint on one of the boards. As the board and components heat up they expand and make a better contact.

I have the same problem with a 19" unit it just started the last month. If I unplug the power cord for 10 seconds then plug it in I can use it the rest of the day until i shut the system down again. I disabled "turn monitor off" in power settings so it will stay on. I too have tried it on different computers,it is in the monitor. No ideas, I am pricing out a 24" feom a different manufacturer.

I read that this problem is caused by a bad inverter board in monitor. We are about to try it. It also takes a while to show an image and if you restart cpu monitor starts normal but when first turned on in morning takes a while.

Monitor won't turn on after a few hours of being shut off

If it EVER works, then the problem is not a failed part, but a weak part. The most likely component type to give you such problems are capacitors. But very few repair techs know how to find such problems, and even fewer have the equipment needed to find the bad one(s) in-circuit. The failure mode is high ESR (ESR means Equivalent Series Resistance). The lower the ESR, the better. Capacitors with high ESR cannot stabilize circuits which demand high pulse currents, such as in switch mode power supplies.

My LG Flatron W2453SQ monitor is connected to my laptop. Since two days ago, when I dont touch the keyboard/mouse for 30 secs the monitor goes blank and enteres power saving mode. I have chyecked the cable...

HI kissakiwi,

In the control panel's power option , you need to change the SYTEM STANDBY settings to never , and then the problem would be solved.

There are three options , turn of monitor, turn of hard disk and , system standby , if you select all of these three to 'never' then you won't have this problem.

Remember you can also change the settings via the screen saver tab when you right click and select properties on the desktop.

Let me know in case you have any queries. Hope this helps ...:)

Monitor will not turn on including power switch

I suspect the power supply for the monitor. Try a power supply from a working monitor. If you have a used computer store nearby, take your power supply to them and try it on another monitor.

There is no need to turn off a monitor using its power switch. Monitors automatically go into standby mode when they are not receiving a signal. In standby mode they use less than one cent of electricity per day. If saving electricity is your goal, raise the temperature in your home by a degree and run the air conditioning less.

Dell E178FPf LCD monitor goes to standby and won`t come on again

Check your Power options in Windows.

right click on the desktop. select properties, Gop to the screen saver tab, click on the power button at the bottom right and check to see if its set to turn off or standby the monitor, turn this off.

Keep the screen saver on and set it for like ten minutes.

Also, on the monitor itself, it may have a sleep or power save option set as the default. check all the monitor settings on the actual moniotr itself.

Monitor goes standby after boot

Look the problem it may not your monitor it's your windows XP. Let me guess you have a VGA/Svideo card. From prior experience I can tell you that dual output Nvidia cards will default to Svideo first, and then "adjust" your windows settings to do so every time even if a VGA monitor is re-connected (HIGHLY ANNOYING). So if the last thing you see before nothing is the Windows XP boot screen, here's how to fix it. Boot to safe mode uninstall your video driver, reboot then reinstall. You can substitute a system restore for uninstalling your drivers if you can remember when the monitor was last working. This really really pissed me off when it happened to me.

Monitor goes to standby mode intermittent.

Sounds like this one needs component-level troubleshooting in the power supply section.
