Question about Toshiba Satellite M50 Notebook

1 Answer


The night before this happened the laptop is working perfectly fine. but when i turned on my laptop the next day, the screen was in total black out. i tried to reboot but the same thing happened.

i also tried to remove the battery out for few minutes then placed it back, when i tried turning it on i heard the sound that it is actually ON but the screen is still in total black out, and there is no display.

this happened months ago, i did the same thing and it worked, the laptop was still in good shape. but this time it is not working anymore. what seems to be the problem?

Am using verizon 9530 unlocked. phone is working, the backlight is active on buttons...!! the screen is not active.. i could answer / receive calls.. can hear the notifications of receiving emails /...

When you get your blackberry screen blackout? After your blackberry 9530 unlocked or a few days after you unlocked your phone? Did you get my point? If you get that blackout screen after blackberry unlocked process try to reset your phone to default factory setting and if still not working try to reinstall your blackberry os, but if you get that blackout screen a few days after you unlock your phone looks like your screen already broken and you need to replace it in your nearest local mobile repair shop.

Can't get my Dell Precision M50 Laptop video to fill the screen at 1024 768 resolution. Video will only fill the screen when I set resolution to 1600 1200. Is there something wrong with my video card?

1024x768 is a native wide-screen resolution. more than likely your video card is fine and your notebook monitor does not support that format without shrinking the top and bottom which defeats the purpose of filling the whole screen. plug the kappy into an external widescreen monitor or TV and it will work at 1024x768.

I turned the my toshiba M50 last night. the next morning i was trying to turn it on, but it was just a black screen. i can hear the sound that it actually turned on but the screen is just black and no any...

If you see a dim image on the LCD screen it means you have a backlight problem.
Connect an external monitor to the laptop and power it up, if you see a clear image on an external monitor, this means your video card is OK.

Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

You are simply in blackout mode. This is so at night you aren't blinded by the glow of a screen. Here are instructions right from the manual to turn on or off.

Blackout Mode On and Off
When Blackout mode is turned on, the monitor display will turn off to
reduce power consumption.
This additional power enhances the sound quality.
1 Touch [VISUAL] on the main source screen.
The VISUAL selection screen is displayed.
2 Touch [OFF].
The backlit-display portion goes out.
3 Touch [OFF] again to cancel the display backlight.
To make the setting, set to “Setting the VISUAL Touch Button” (page
If any button on the unit is pressed during Blackout mode, the
function will be displayed for 5 seconds to show the operation before
returning to Blackout mode.
While the backlighting is turned off, the function indicator

Screen is complete blackout when I turn on my hp compaq c6000

You either have a screen that has gone and needs to be replaced or a cheaper fix and usually a more likely one is that the inverter in the screen has gone out. The inverter is quite cheap, around $34.00. Try it
