LCD screen goes blank and computer stops functioning
The LCD display goes black at various times....sometimes at start up and sometimes after being on for a while. Sometimes if you tap the lid to the laptop it goes out.
The power is on but nothing will work. Any suggestions?

If you shine a flashlight on your black screen and look real hard for the icons on the desktop. If you can faintly see them that means your LCD Inverter is bad. You'll have to disassemble the LCD Screen to get to it. In the mean time you can attach another monitor (LCD Flat Screen or the Old style fat CRT) with a VGA cable to the vga port on you laptop. Once you have it connected hit the FN (Function Key) + (F1 thru F12) key that that corresponds to the external display. Hold the FN Key while you hit the Function Key that is for the external display. The key might have the words LCD/CRT on it or it might show a display symbol. That's the key you want to hit while holding down the FN key. This will cause the desktop to display on the external monitor and verify that there is no problem with your Video Card inside the laptop.
fs31, Hi, I'm 12fixlouie. Will need more info about your Lucky Goldstar unit before I can give you advice on your "sometimes" black or blank n black screen monitor. What is model nuumber and when was it made? Is pc fully functional with spare monitor connnected? Did this problem just happen? Is unit covered by LG warranty? Did LG display work perfectly the day before? Do you know how to do the flashlight test when screen goes to black? Read my fixya profile for a little bit to understand the top two causes of ccfl backlit lcd monitor failure modes. Then do additional post on fixya and let us know what you are willing to do about your display. Your monitor's smps/ccfl inverter supply may need refurbishment (rebuild) because of common known problem affecting ALL brands of lcd monitors!!! Do your research first!!! Reading is free. Then come back here and rate this response if you learned something and feel this was helpful. 12fixlouie
it looks like the Inverter's gone in your screen, it works like a starter in a florescent tube, it 'kick starts' your screen to come on. Turning it on/off many times eventually 'kick starts' your screen and makes it come on eventually.
Most portable computers have a monitor loop-through or simultaneous viewing function. Press the FN +F4 function keys on the portable computer to switch the image from the portable screen to the projection screen or to toggle through the following three options:
Liquid Crystal Display (LCD): Output displays only on the portable screen.
Cathode Ray Tube (CRT): Output displays only on the projection screen.
CRT/LCD: Output displays on the portable screen and the projection screen.
It appears that the display resolution set in your display properties is out of the range that the LCD can display.
Boot to the ENABLE VGA MODE by pressing F8 to get the Windows Boot Menu. If you can get to the desktop, then go to display properties, and see if you can change the resolution to higher settings and maintain video. (If the video blanks out, then it should revert to the previous setting in 15 seconds)
I have a sony cybershot DSC-S650, the LCD was very dark and could not
see anything except if I pointed it at a bright object, everything else
worked ok. I could take pictures but could barely see them in playback
I took it to Sony authorised repair outlet and was told
the CCD was damaged, they charged me USD $55 to repair it (in Quito,
CCD malfunction, common with Sony manufactured CCD chips. You are in luck, its a free repair regardless of warranty date. http://www.usa.canon.com/consumer/controller?act=ModelInfoAct&tabact=SupportDetailTabAct&fcategoryid=223&modelid=8044#
