    You need to change the lcd display lamp, this will solve the loss of luminosity problem. You may also need to change the lcd inverter, which is a small board connected to lcd display, that must be the cause of screen flickering. If you give me make and model for your laptop, and your location, I can find a dealer in your area and give you further instructions.
    To replace lamp and inverter you will need to disassemble your laptop, removing display from hinges. And opening display assembly. Before changing the inverter check also that the flickering problem is not due to a defective lcd ribbon cable inside your laptop.

    Here is an example on how to change the backlight inverter on a Dell laptop. You will find more models and tutorials on same site.You will need the right schematics/service manual for your laptop to do the job.
    Remember, opening a laptop is never a simple operation if you do not have experience in servicing laptop I suggest to contact nearest service shop and get the inverter changed from them.

    regards

We have a Toshiba Satellite lap top. It was working about an hour ago, when we down loaded a BIOS upgrade from 1.4 to 1.5. After the down load and reboot the lap top now has a black screen with no wording....


BIOS updates sometimes cause the motherboard to revert to its default configuration. I recommend that you go into the BIOS setup and examine the Boot Devices and Boot Order to make sure that your hard drive is selected as the first boot device.

Good luck!

My hp pavilion dv6000 laptop does not turn on, the blue buttons light up, but the screen stays off


Try it without the rechargable battery connected sometimes the battery shorts and causes problems.
Do you have FN[function] keys at the left side. touch FN key with something else and see if screen comes back.Sometimes you can turn off the screen to send it to the back connected monitor.Connect (extra if you have) an external monitor to the back (vga) connector.If that shows, then you have to ""flutzz" with the FN(function) & F1-F12 keys

My computer screen keeps flickering sometimes it will go completely black.


this most likley is s screen connection problem. You need to take off the top case for the screen. Usually two screws to a side. May differ with machine company. once screen case is off, there us usually a cable covered up up silver tape or white tape. take tape off and push two video connections togeather. Replace tape and put cover back on re-install all screws. If this does not work , you need to replace the back light board. Good luck!

Flickering lap top screen sometimes screen doesn't light up at all


There is a switch on the top of the laptop that "detects" whether or not the laptop is open. This effectively shuts off the screen when the laptop is closed. Look for a "bump" on the screen face that corresponds to a depression in the laptop. This should be the "switch" mechanism. If the actual switch in the laptop body is stuck, you could see the symptom you describe.

TOSHIBA LAP TOP


If you move your laptop screen to were it works sometimes and doest work other, it sounds like it could have a loose connection in the ribbon cable. Most laptop lcd screens are connected to the main board through a brown looking ribbon cable. if this cable has become loosened, then yes it can be a DIY type job.

if you attempt to take the laptop apart, i sugguest you keep a record of what type screws go where.

Good luck!
