    The power supply is alright and the processor is working, There is a sound of it running. The black out started when i turned on the power. The keyboard seems to respond to touchs, indicator lits when i touch caps lock. The company manual's troublshoot info says " if lcd blacks out it may be due to power conservation system shuting down your lcd" then " use function keys". I tried to increase light through the function keys but didn't work.



    Sir, since i can't use my laptop now i can't respond to you as soon as you expect b/c i have to go to an internet cafe to see your e-mails. Anyway i expect to have the best tech. advise from you.

    Thanks

    Did it black out whilst in use or just didn't work when you switched on? Have you checked the power supply? Any indicators lit?

Sorry, didn't realize it was a laptop. Most likely explanation is a faulty backlight lamp or inverter; can you see anything at all? If there's a very faint image it's probably the lamp.

Screen gets black


Typically the graphics card went out. Other possibilities include, loose monitor cable or short in the cable, or incorrect graphics driver installed or missing, or monitor is shot (least possible). Things to look for: When booting up are you able to see words in the monitor or is there a series of non-regular error code beeps? If beeps then most likely your graphics card is either loose or fried, or incompatible. If you it works fine, but the light on the monitor turns orange and screen goes black, then it's most likely a loose monitor data cable or there is a short in the cable, or monitor's power cable is loose. Then check both connections, power and data on the monitor, and also where it hooks to the computer make sure it's screwed in snug.

may be this is you are mentioning there is no display in your monitor or u have already getting the boot display. if u getting the boot display it must be the problem of your monitor inverter board in side ur lcd. otherwise it must have your computer memory not working properly so u must clean and re install your memory first.thank you.

Lenovo 3000 n100 lcd display works but only less than a minute before display goes black. Connect an external monitor and it works fine.


possible problem is your led light on your LCD or its Flex. you might need to have it replaced. Try to check your LCD when it turns black under the light if you can see a dark image of your desktop. If you can see your desktop then the backlight has a problem. If there is no display, your LCD needs to be replaced.

3 BLACK LINES THROUGH SCREEN. One 1 in from top, one through middle of screen and one 1 inch from bottom of screen.


The LCD panel is dying. It may only have a line or two of dead pixels but it may also get worse over time. Often caused by poor connections indide the monitor from the LCD panel to the flexible PCB. Basically the PCB ribbon is pressed against the LCD and as the padding gooifies it looses contact. This has been an issue since the first LCD screens on calculators etc.

Yes i have a black dot on my new 2008 toshiba notebook.Do you know how to fix it.


If it is just one pixel that is black, you cannot do anything about it. It is what we call a "dead pixel". The best thing to do is to send it back in to the manufacturer and get a free replacement.

It's not the answer you wanted to hear, but again, there is nothing you can do about it.
