If your LCD is on but blank then it means its not compatible with the picture being send from the CPU VGA unless its faulty itself.

  1. Try reducing your Computer display setting to those specified as native or default setting of your monitor. Offcoz to do this you ned another monitor preferably external. Boot up your machine with an external monitor connected if it lights up the external monitor then go to your desktop (if using windows) right click select properties and goto settings and reduce the VGA card setting to those of your LCD or just lower settings. and then restart your computer without the extrernal monitor.
  2. If it does lughts up your External monitor but does not light up your LCD on rebooting then its possibly that your video cable to the LCD is broken and needs replacement or that your assuming you saying that it powers up
  3. If it fails to light up the external monitor as well then if means your VGA card is not working (assuming you used modern CRT monitor to test it). If its up to the third option you need to replace your VGA card assuming its not onboard for a laptop. If its onboard please check if your machine is working or running properly when your machine is not diplaying like making windows welcome sounds etc cause it might be just your RAM that needs replacement
P.S. Try to give more details when you ask to make your questions easier to answer and answers more helpful

Check that the LCD screen adjustment has not been dimmed or darkened. If that is not the case, then a component is or has most likely failed.

There is a white blank screen when i turn on


A white blank screen usually means that there is no data reaching the LCD. This can be caused by a bad video card, bad cable, or bad LCD. Rarely, the cable is just unplugged on either the back of the LCD or on the system board (or video card if separate).

Mag lcd question


Hey CBernard84,

While a blank screen could be caused by a controller, it could also be caused by something simple like the settings on the controller.

Question: When you boot up, does the screen show the Power On Self Test then go blank? If yes, the screen refresh rate is most likely set too high.

Comment me back, if this is the case. I can walk you through the procedure.
Hope this helps,
Mike

Stupid blank screen on my Craptop


Could be a simple video driver problem, try starting up your laptop in safe mode (Pressing F8 on boot up). If and when screen comes up highlight 'Start Windows in Safe Mode' Next a list of startup drivers etc will stream down the screen and tell you you are starting in safe mode, allow this. If your lcd screen stays on then it's a driver problem, go to add/remove programmes and uninstall driver the driver and restart your laptop. This should then start in VGA mode all icons will be bigger than normal. Either re-install video drivers from setup/restore disk or go to laptops manufacturer website to download drivers. If no screen even in safe mode LCD probably dead. Please rate solution.
