    Hi my friend,
    I am still facing the same problem,, (unable to try my notebook), I guess that the pc is working properly,,, due to the reason that the VGA card once the LCD monitor works properly after the repeated restarts ,,
    The question is why the monitor needs lots of time to be heated,?

    I tried to turn off the computer and restart it within few minuets and was doing well,, .. which that means the monitor was still hot !!!

    Thank you again my friend
    Jay

Hi!
You might also try to connect another monitor, to check if has the same behavior. In this case the problem is generated at graphics card or from loosen cable connections.

Dear admin, i would like to ask you something... i have monitor ACER AL1716.. recently when i started my PC, the monitor suddenly turn on and off continously (you know when we turn on monitor, it showed...


I suspect that the problem is with your PC, and in particular your video card. The fact that your monitor is displaying the logo indicates that the monitor is not receiving a signal from your computer. You may want to try hooking the monitor up to another PC and see if that is the problem. The fact that your monitor turned off and on for a few times also indicated that the signal from the PC video card was sporadic and finally failed leaving you with the monitor logo. Disconnect the PC from the monitor and see if the logo is there. Also check the cable from your video card to your monitor to see if the cable is bad. You may have to borrow a video cable from a friend to test this out.

Make sure that your computer isn't going into Standby or Hibernate mode. You can test this by briefly pressing the power button and wait to see if the screen comes back on.

When I start my computer up my Philips Monitor


Good day sir/maam, hi, the problem may not be your monitor but your PC, they produce the same symptoms if your PC has no video to display. does your monitor led/lamp lights up as turn on your computer? If you want to test your monitor, go bring it to a friend who has a computer, test it there. if it works, your pc has a problem, so try the following first.
  1. Open you PC side cover, locate the memory module, remove the momory by releasing the side clamps. clean the contacts using an eraser (pencil) then put it back, you will clicks as you put it back on, test again. Do it several times if the first try fails.
  2. Check your Power supply, does it gives out hot air exhaust?
  3. Did you hear one beep, (good) or several beeps(bad).
  4. As you power on the pc check your keyboard light, first set of lights (Num lock+Caps Lock+ Scroll lock) then second set of light (Numlock only). At this point your pc is good.
Hope this helps, let me know your progress.

Is video card/motherboard dead?


Do you normally "logon" to the computer or does it load completely by itself.
If you wait for the system to "settle" you can test the computer w/o the monitor:
1. Press the "windows logo" key on the lower left of your keyboard
2. Press the letter R
3 Type WRITE
4. Type a few random letters ~ran~dom~
5. Press this three key sequence:
[Alt]F [P]

(Alt & F) together then the P key

Your random document will print if the computer is actually running.

ok, I suggest you reset your BIOS by removing the mobo battery or by shorting the "reset" pins next to the nattery or BIOS chip.
Go from there...

LG1717S - Power light flashing - no image.


The monitor is probably on protection.

To start unplug monitor from power and from computer and test computer with different monitor to find out if it is monitor or computer fault.

If it is computer fault and no video signal , then test:

  • Video cable.
  • Video adapter on PC (sometimes integrated on motherboard)
  • Motherboard.

If it is monitor fault , then the monitor is on protection.

When on protection you keep having a flashing led on front of the monitor , and monitor turning off by itself after a while, that indicates a fault condition.

The flashing light indicates a diagnostic state called protection.
When the Monitor goes on protection there are only two possible causes.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or a broken contact, identified an internal fault and kicked in , starting the flashing light.


If you are in situation one, then the monitor will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

Common faults that can occur are a blown capacitor on power board, faulty inverter board, faulty input board, or a fault on LCD Digital Controller board.

Check also the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you can get same flashing state because of the video cable.

Try moving the video cable, and if the cable is not built in, then also try a replacement cable.

If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.

LCD Monitor - green power light blinking - nothing on monitor


Carol,
It sounds like your computer is putting the monitor in power save or sleep mode, and the monitor doesn't respond appropriately. The monitor might be faulty, or overheating. Make sure there is adequate ventilation around the monitor, and that it is clean and free from dust around the vents on the case.

Another thing to try is to check your computer's screen saver and power saving settings. Try turning off the "turn off monitor after [interval]" setting and see if the monitor still shuts off after several hours.

Good luck, hope this helps.

Power saving is the default the monitor goes into if it doesn't get the correct signal down the cable wires of the computer. There might be three culprits:  (1) the cable between computer and display (most likely), (2) the display itself (unlikely since you see the LG logo) and (3) the graphics card inside your computer.  #1&2 are easy to check by swapping with a friend for troubleshooting. #3 is tricker and more expensive and might require a savvy friend or a computer repair service (between $60 and $100/hour for labor) plus between $40 and $80 on Amazon.com for a new card depending on whether you need a analog or digital one. Don't waste money on super costly cards unless you use your computer for gaming.

You my friend have a bad backlight. Inside thes LCD monitors there a little tiny flourecnet lights that help the LCD project the images so that you can see what is being displayed. Sounds like your backlight has gone bad. These can be repaired, but can be costly! These things happen often times, 90% of the time I am replacing the backlights to various monitors. Sorry, but I am certain it is your backlight!
