Question about Computer Monitors

Monitor turning black

All of a sudden my computer screen on my apt. computer went to "black". I thought it was in the sleep mode so I tried moving the mouse. That didn't help. I then turned the monitor off then on...you could see the screen for 1 second then it went black again. I tried unplugging everything and plugging it back in. I tried to just turn computer off and on again. Nothing has worked. I now have just turned everything off.

    Yes, it sounds like the monitor tries to come on but the main-board never gets the GO signal.



    You can get them from eBay. Most monitors use 2 of them.

My 15" LCD monitor TTX went to sleep mode and never return back


mike_garzan, Your monitor will need some work done on it!! Do you know the "flashlight trick" that every owner of an LCD monitor with "cold cathode-fluorescent-lamps" should know how to do when the BLACK screen of death makes it presence known? Do this test first! It is a very easy test to do. 1. With a KNOWN GOOD pc fully booted to the WIN-desktop showing on a GOOD Monitor have a friend tap the CTRL key on the keyboard every 30 seconds or move the mouse to ensure that the pc won't go into sleep mode. 2. Power off the good monitor and disconnect it from the pc. Now reconnect the TTX9151 to the pc and wall outlet power. 3. Then and only then turn on the monitor and make note of what happens. Did you see or not see the WIN-desktop appear?
4. Now for the flashlight test. Even though the LCD panel appears BLACK, shine a bright flashlight about 1" from the screen's lower left corner and make note if you can see the Windows START icon even though the screen appears to be BLACK. 5. Turn off TTX9151 or yank the plug from wall outlet, and disconnect from pc. TEST IS DONE. Reconnect good monitor to pc to get back online. The test was to evaluate the current status of the "switch-mode-power-supply" and the CCFL inverter circuit DC source. If you could SEE something on the BLACK screen then you know that half of the SMPS is working and sourcing voltage (+5 or +3.3v) to power the vga/lcd interface board! It also means that the SMPS is not in FULL SHUTDOWN mode and only has a problem sourcing voltage(+12v to +18v) to the CCFL inverter circuit which generates 800v to 1200v ac to light-up the CCFL's that are hung across the rear of your LCD panel to produce the WHITE LIGHT needed to see what is on the screen. Now, if you didn't see the WIN-desktop, then the SMPS is probably in complete SHUTDOWN mode trying to save itself from a CATASTROPHIC, NONRECOVERABLE failure! (eg. smoke and fire) Put the TTX9151 in a safe place and get back to me with results of the TEST. lmistyrel and on aim.com or do a comment to your original post above on fixya and I'll give you advice as to what you need to do about getting it repaired or other actions/options you as a consumer/user of LCD displays have open to you. Bye for now. 12fixlouie

Monitor Goes black, or flickers on and off


The high pitch sound is coming from the inverter. It is faulty and needs to be repaired or replaced. The inverter supplies high voltage to the CCFL lamp, this lamp gives the backlight to the LCD so you can see the LCD images.

Can't switch on monitor screen


You must go into the BIOS of you computer and turn off the sleep mode and also in windows. Disconnect the monitor and power it on without hooking it up to the computer. If the monitor turn on and is working , then hook it up to the computer and try with with the sleep controls off to see if it works correctly.If this works you must check the owners manuals of the motherboard and monitor for the correct operation of the sleep mode functions.Then reinstall the sleep mode operation and see if everything works correctly. If the monitor fails to work. Try the monitor on another computer and see if it will function. If all this fails to get the monitor working , then you will need to have the monitor tested in a service center to find the problem and have it repaired. You should also check your computer on another monitor just to maker sure you don not have a problem with the computer too. Hope this helps you with your problem.

Monitor in sleep mode


This problem could be caused by windows or the monitor .You need to hook up your monitor to another computer and see if you get the same response. If you do check and see in the owners manual if there is a control for power management.Find the control and try to adjust it, or turn it off. If all this does not work than you need to take the monitor in for servicing. If the monitor works,you may have a problem with the computer bios or windows itself. Check all power management controls in the bios and window settings and see if you can find the problem.Check the Microsoft website for this problem with your operating system and a solution. Hope this helps.

Sharp light turns green thern turns yellow screen goes black


it is going into sleep mode, good luck with this.... i am currently asking how to get my hard drive to quite putting my monitor into sleep mode.

although it hasn't worked for me because my screen stays black, one of the options given to me is to try to start in safe mode and then adjust your settings to "never" on the energy/sleep/hibernate mode

some one else suggested that i remove and reseat the video card

hopefully one of those will work for you

No DVi input, then computer goes to sleep


Hi publicworker,

I had a similar problem whereas my monitor went to sleep mode after a few minutes. I'm running an HP LP 2065 in dual mode with another HP flat screen. However, I did resolve the issue after resetting the output settings.

How to do that:
  • right mouse click on the desktop
  • select graphic options
  • output to
  • extended desktop
Maybe some changings/modification will help you too.

When I select sleep or hibernate mode - the monitor stays black...


Hit the keyboard keys. It is better to just turn sleep and hibernate off and just use a screen saver or tun it off.

CRT Monitor-Compaq presario VM700


Hi Snandy, I absolutely despise monitor and computer sleep or hibernation modes. Before I started routinely disabling this on all the computers I supported my users were always having problems no matter how computer literate they were. I know this sounds simplistic and you may have already done it but have you just unplugged the monitor? If that doesn?t work maybe the PC itself has gone to sleep as well. Try moving the mouse, hitting a keyboard key. If that doesn?t work try pushing the power button on the computer to turn it on. If all else fails pull the power plug on the computer itself, plug back in and it should start up. I would suggest disabling all of this via Windows Power settings in the control panel. Let us know if you have any other questions and again please don?t forget to rate the post.
