Black screen, no sound?

The screen on my laptop is black. I went out and came back in and it was black and I didn't hear sound either. I was playing a video game so the game still had to be open but there was no sound so I'm guessing it is not just the screen? I boot up the computer and I don't hear sound either.

I do hear what sounds like a fan.

I was playing WoW and went afk, when I came back there was no sound and a black screen. I thought it was sleep mode but I guess not.


I turn off the laptop and in the dark I turn it on and there is a small flash but the screen still looks off. It is an eMachines627.

I was meaning to buy a new rig and this one only cost $300, so how much would it be to repair this?

I already unplugged everything and held power button..

Hi Jon,

Did you try walking out and walking back in again? :p  I kid! The LCD screen or the inverter that powers the lamp may have died. You can try searching for a screen replacement and/or replacement inverter. The cost of a new screen is usually around $100 to $150 - sometimes more - but it depends on the make and model (and the vendor's mark up). The inverter's price can range anywhere from $10 (used) to $50.

If your fans are spinning and the LED indicator lights still light up, chances are the board is still POSTing and things are otherwise working. Worst case is that it's a problem with the GPU, which would cost considerably more to fix than aforementioned prices.

Yes the lights are still working haha. There is no sound either, is the screen and speakers powered by same thing?

Well, everything is powered through the board, but the speakers are driven by a different voltage (which varies depending on the speakers). So one or other failing would not inherently cause or imply the other is bad (I hope that make sense).

Why do you ask about the speakers?
