How do I repair my 19in LCD monitor, it receives video signal, but goes black screen?


Connect the "bad" monitor to the VGA-out port on a notebook/laptop computer, to see if it works normally when connected. If not, then the monitor is "dead".
If it works fine, check the "screen-resolution" of the computer's video-card, to see if the values exceed the capability of the monitor.

Acer Aspire 5536 only gives black screen when i connect power supply


  • Nothing is more annoying than a monitor that refuses to turn on. Make sure your Acer monitor is plugged in to a functioning outlet. If it's plugged into a power strip, try replacing it with a new one or moving the plug to a different outlet. Ensure that both ends of the power cable are plugged in firmly and securely, and that the connection to the monitor is not loose.
Cable Issues
  • Your Acer LCD monitor will usually accept DVI and VGA inputs. If you have an older computer, a VGA cable should work fine. If it doesn't have a VGA port, you'll need to obtain an inexpensive DVI to VGA adapter at your local computer store. A DVI cable, however, is compatible with most modern computers and offers superior picture quality over VGA. Make sure you're using the cable that's compatible with your system, and that you have the proper conversion adapter, if necessary.

Black Screen=Bad screen or motherboard?


You have done your homework, but first! remove main battery and press power, if no change! take out one stick of ram and power up, no change remove second stick and put the first one back and power up, if no change remove hard drive and start computer to see if the logo image comes back. Now reseat the hardware back in place and start computer, if no change! the motherboard is the problem and replacement the only option.

Can't connect to external monitor or to Sony bravia tv. When vga connected nothing happens at all on laptop but external monitor says " check cable" ( have tried another cable ). If connected in power off...


You need to:

- Connect everything with the laptop turned off
- Boot the laptop
- Use the Fn key plus F8 or F9 (I'm trying from a small picture of the keyboard!) to cycle through the external display options.

Monitor powering up and down at random


Check monitoc cableing. This might be the cause of cable having loose connection on the back of the monitor. (I mean data cable (VGA) not power cable)
Did you have a chance to check with another monitor? Will picture appear when cable on the back is moved?

Does this happen when you logon to bios screen? REstart PC and keep pressing F2. You will see bios screen - test unit there. If that is ok then everything is fine with the monitor.
Let me know if issue is not solved by checking cable and I will provide you futher troubleshooting steps.
Thanx

My HP monitor (f50) has malfunctioned


Try these 2 steps if they don't work get back to me :)

Step 1. Connect the video cable and turn on the computer. What happens?
  • If the monitor screen remains blank (no startup screens or onscreen display messages), the monitor must be connected to another computer using a different cable to determine if the monitor is bad. Skip to the Step to connect the monitor to another computer.
  • If the monitor is capable of displaying boot screens but is unable to display Windows, use the following steps to set the computer to a compatible resolution:
    NOTE: Find the native display resolution for your monitor in the User Manual or in the product specifications for the monitor model. If you are unable to find the native display resolution for your monitor model, temporarily use 1024x768 for troubleshooting purposes.
    1. Turn on the computer and press the F8 key repeatedly when the first startup screen appears.
    2. If you are using Windows Vista, select Enable low resolution video (640 x 480) , press Enter , and wait until Windows opens. To set display settings that match the monitor, use the steps in the HP support document, Changing Display Settings, Background Image, and Screen Saver in Windows Vista . If you are using Windows XP, select Enable VGA Mode , press Enter , and wait until Windows opens. Continue using these steps to set display resolution. If you are using Windows 98 or ME, select Safe Mode and perform the following steps to enter into a standard VGA mode:
      1. Once Windows opens to the desktop in Safe Mode, click Start , and Run .
      2. In the Open field type msconfig and press Enter . The MS Configuration Utility window appears.
      3. Click the Advanced button, and select VGA 640 x 480 x 16 if it is available.
      4. Click OK and restart the computer.
      5. After Windows opens, click Start , and then click Run .
      6. In the Open field type msconfig and press Enter .
      7. Click the Advanced button, and remove the checkmark next to VGA 640 x 480 x 16 .
      8. Click OK . Do NOT restart the computer.
    3. After Windows opens, right-click on an open area of the desktop and select Properties (Windows XP, 98/Me) or Personalize (Windows Vista).
    4. In Windows Vista, Scroll down and click Display Properties . In Windows XP, 98, or Me, click the Settings tab.
    5. In Windows Vista, select the native display resolution size using the Resolution slider. Set Colors to Highest (32 bit) . In Windows XP, select the native display resolution size using the Screen resolution slider. Set Color Quality to Highest (32 bit) . In Windows 98 or Me, select the native display resolution size using the Screen Area slider. Set Colors to True Color .
    6. Click Apply after you have made your adjustment. The screen should blank out temporarily and come back.
    7. If you are satisfied with the new display settings, click Yes on the Monitor Settings windows. If you are not satisfied or if the screen just goes black, wait: Windows sets the screen back to the way it was before. Try another setting until you find a display configuration that is compatible with the monitor and meets your needs.
      NOTE: If the native resolution is not available, download and install updated video driver software for your computer. Updating the video driver software can add more resolutions (graphics modes).
    8. Restart the computer. The monitor should now display a full screen image in high quality. You are done.
Step 2: Connect to another monitor
Using a different cable, connect the monitor to another computer that has video. Turn on the monitor and the newly connected computer. What happens?
  • If the monitor works, the video hardware on the original computer is likely to be the source of the problems. You can try connecting the original computer to another monitor that works to update its video drivers.
  • If the monitor remains blank, repair or replace the monitor.
