Question about LG Computer Monitors

1 Answer

Monitor shuts off during boot. Let the machine boot full up, hit the power button, the monitor flashes windows for a split second, and goes back to power saving mode

My monitor just went to power saving mode right after I was playing CoD4. I've got an older monitor hooked up just to keep going, but, I was needing to know if this monitor is trashed, or, if there's something else I can do to fix it. It's a LG Flatron L1932TQ-BF. I'm running an BFG 8800 GT OC and have tried both analog and digital. Once the machine is up and running, I can click on the power button and windows will flash for a split second, and then it will go back to power saving mode. Any suggestions?

    I take back what I stated about the power saving mode. It will start to boot, monitor will come up showing the boot sequence, and then go blank. It stays powered on (blue light), and will flash windows when I turn it off and right back on. I've tried two different machines, both with the same outcome.

    No luck...Refresh rate is set at 60 and the others are hidden. I had been running the same setup for more than a year. It just died out on me after a game of Crysis. Power light is still on, but if I turn it off and back on real quick, the screen will pop up w/ windows for about 1 sec and then go black again. Has me stumped...

    I'll give it a shot after work this afternoon. Hopefully that's the case. I've got it hooked to my son's machine right now and am having the same prob, but I'll try to go into Safe Mode and see if I can get into it or not. I'll let you know how it turns out. Thanks again!!

Hey there Celius,

Chances are the 'Refresh Rate' somehow got set too high for the monitor. On flatscreens , the result is a black screen.

If you have an old monitor (crt type) hook that up temporarily and reboot.

  • Right Click the Desktop
  • Click Properties
  • Click Settings
  • Click Advanced
  • Click Monitor
  • Lower the refresh rate or set at optimal
  • Check the box 'Hide refresh rates this monitor can't display'
Shutdown, Switch back monitors and try it now.

Good luck
Mike

    You're right about this being a stumper.

    How about trying to boot in safe mode (hit F5 or F8 during startup). If the monitor stays running at least we know it's not the monitor.

    You've already tried it on a different machine? Same results?

    Try the Safe Mode thing anyway. You never know what you're going to find out out on the weird ones.

Monitor will not stay powered up


It is possible that the monitor is going back into "Sleep mode" meaning it is not detecting a valid signal from whatever device it is plugged into. I would try replacing the cable that is connecting the monitor to the PC or Console. As a trouble shooting step try pulling up the "Menu" on the monitor itself by pressing the "Menu" button on the front panel of the monitor, if this does come up then we can say that the LCD itself is most likely working.

Blank Screen & flashing button


It is one of three things, One is that it's not recieving a signal, mine flash when the computer is shut down, several monitors do this now. The second is that the either the video card is in need of service, or if you don't have a video card in your machine, it is either a connection that is intermittent, check the other end of the cable, or the monitor is in need of service, there is a circuit board that gives it a boost on start up. How old is the monitor and what brand? all the info is needed to go any further, thanks, if it is 5 years old more or less it is the monitor gone bad, more than likely

Monitor flashes on and off!


Sounds like you have a bad connection from your monitor to your computer. First check and make sure the connection between them is tight. Does your computer boot up and run though? If your computer is not booting up the monitor will default back to the flashing green power light

Black screen


How old is the computer? Make sure that the power light comes onto the monitor when you plug it in, should be orange and then turn green when video card syncs with it when PC is turned on. If you are getting black screen when PC is powered on:
1. Bad video card
2. Bad video cable
3. Bad monitor
1Solution: Try using a different monitor attached to this same PC and see if it works. If it does, then its the monitor, its cable, or its power supply. If it doesn't work, then its the video card or the video cable coming from monitor.

ViewSonic Monitor has trouble to wake up after been shut down?


Ok sounds to me like a power supply problem.. this a a fairly common symptom. I suggest that as a temporary fix you set the monitor to NOT turn the power off to the monitor in sleep mode if possible, in your power settings for the monitor.

Monitor flashes image for split second then goes blank but green LED flashes as well


while the monitor is still powered on, but with the LED flashing, unplug the monitor from the PC. press the power button, and the monitor should go off, now plug the pc back into the monitor. Turn the monitor back on and it should work.

Occasionally this will not work for me, but if I repeat it it normally works

Hope this helps - my problem is intermitant so it may be different to what u guys have
