When I turn my Toshiba laptop on the screen comes on for 1-2 seconds then goes black. It keeps on loading windows because I hear the sounds of windows loading and when I type in my password it makes the sounds like my desktop is loading but no image on the screen, I shut it down and restart it and it does the same thing, just shows an image for about 1-2 seconds then black :(. I have tried it at least a dozen times. Anyone have any ideas? Thanks

 

Just noticed that the cooling fan does not seem to be running, could it be over heating on me?

Have you tried plugging in an external monitor? Does the computer make it to the windows loading screen?

No I have not tried an external monitor yet and no it does not make it to the windows loading screen before I lose the screen, it shows the Toshiba logo screen before bios loads and then it goes black.

No I didn't sorry I'm on my mobile phone. If you don't have access to another monitor you can check If its the backlight or the LCD. When the screen goes black use a flashlight and hold it at an angle close to the screen. If you can see windows loading its the back light or the inverter for the LCD. Its difficult to see anything using a flashlight you may have to try different angles. If you see nothing or an external monitor does not work, first try the display switch keys ( usually a function key) and see if either turn on. If nothing shows up it could be the graphics chip

If the cooling fan is not running the computer will shut itself down or disable components to protect itself.

Good news so far, Its likely one of two components the inverter board

Or the backlight

Both of which are cheaper then a new laptop. That would be the case if the Graphics chip overheated and  :rip: . In General when you replace the LCD it comes with a new backlight, they do not (unless specified) come with new Inverter boards. I have not replaced a individual backlight so I am not sure how much labor is involved if you have a shop do it. They may just replace the screen

So would you recommend buying a new LCD screen with the inverter board? Where would I get a new screen if thats the way to go, newegg?

I order most of my screens from amazon.com, MLC distrubution usually has the lowest price/shipping. When you do order make sure you match the model numbers of the screens closely. If you only search for Laptop model number you may get a link to the wrong screen. 

 

Edit: To answer the first question I would test the laptop with an external monitor, then replace the screen if the external works

Thanks again for your help. Stupid question, how do you hook up an external monitor to a laptop? Also where would I find the model # for the screen?

Most Dell laptop and desktop computers will come with a handy utility already built into them for performing at least some form of basic diagnostics when you need to do a little bit of preliminary troubleshooting. This article will show you how to test the hard drive which is installed in your Dell laptop or desktop computer.

Sneaky,

 

I hooked up an external monitor and it worked fine, so i am assuming the back light on the screen is bad and i need to order a new screen. What is up with the post above is that some kind of spam? Didn't look legit to me so I ignored it.

 

Checked MLC distrubution for a new screen, they do not have the model I need, any other places I can look that you recommend?
