Hello,

 

I have a laptop running windows vista that when it starts up nothing displays on screen.

when i connect it to an external monitor everything is perfect so i presumed inverter problem so i bought a new inverter

but i get the same problem with new inverter so now i presume backlight problem.

 

So is it possible to change the backlight or will i need a new screen.

Laptop is an Emachine E525.

 

Thanks for any advice.

If the screen worked previously, then I'd suggest doing a hardware reset.

 

Try unplugging the power cord and removing the battery, then hold the power button for 30 seconds. After that, put the battery back in and turn on the computer to see if that fixed the issue.

 

If that still doesn't solve the problem, I would recommend putting Memtest86+ on a CD/DVD and booting from it in order to see if the RAM's not faulty.

 

If you're still experiencing issues, then I'd definitely be willing to bet that the issue is with the screen itself.

Since the laptop works with an external monitor it wouldn't be a RAM problem.  If it were a RAM problem it would be the same with both screens.

 

A Hard Reset or Forced Reset reestablishes the software connections between the BIOS and the hardware.  But once again, if this problem doesn't repeat with the external monitor this isn't likely to be the issue.

 

Usually if the problem is the back light you can take a strong flash light and shine it on the screen and you should be able to see the desktop.

Whoops, that makes more sense than what I was thinking. My line of thought was that the computer wasn't recognizing the regular display and I was thinking of possible ways to troubleshoot that first and foremost, but in this case, it makes more sense to do the process reverse of mine.

Sorry for the mistake on my part; I'm struggling to even remember how on earth I let myself not try a bottom-up approach.
