It is most likely a hardware problem. Try re-booting it. Sure you'll loose all your memory, but at least it will work again. If you go on the manufacturer's website, i am sure it will tell you how to do that.

Hope this helps!

I've had my compaq presario cq61 for about 2-3 years. A while back it would occasionally have a kind of shaky/blinky screen but just in the past week it's like the screen has stopped working.


The problem may be due the graphics card or data cable or backlighting.

The data cable can be severed over time though opening and closing the display. This can be replaced.
The backlighting/inverter dies, some-times the windows desktop screen can be seen if one looks carefully. This can also be replaced.

Try connect your notebook to another computer's monitor via VGA or HDMI out.

If this works then the problem lies with your LCD screen.

Take care!

Laptop screen flickering


The video inverter may be failing, BUT...

More than likely the backlight is failing. If you can still see a VERY faint image on the screen this is almost certainly the problem.This is a very difficult fix. I recommend a replacement LCD.

It MIGHT be a bad lcd cable. With the laptop on, slowly open it from closed to open and back again and see if there is a position where the laptop screen does not flicker or turn off, [or if it does turn off if it turns back on.

If the screen goes COMPLETELY black then your GPU is failing.

The screen on my Toshiba Tecra laptop has been flickering the past couple of weeks. Today, after using for about 5 minutes, the screen went completely black. I had to reboot to get the screen lit again. ...


Sounds like an inverter problem. If your laptop is still under warranty, send it in for repair. If not, and you know a little something about taking laptops apart, then you can take the screen a part and see the inverter behind the screen. It is long and skinny and has wires coming out of both ends, one side going to bulb, the other to the motherboard. Inverters are fairly cheap, and easy to replace... it's getting to it that is a pain.

Dell Inspirion Laptop Screen Randomly Flickers, Then Blacks Out


not to get to concerned just yet, a few tips, when you press on the top of the laptop case by the screen area in the back of the laptop do you notice the screen flickering off? and when you let go dose it come back on? if so this can be a faulty wire or bad inverter, they are actually both very simple to fix and relatively cheap fixes.

Screen is fine when I first turn on TV, then goes black


Sounds like you dlp lamp is going out. That's a pretty old TV and if you are still running on the stock lamp this is exactly the type of thing that will happen. The lamp model for this particular tv is the ty-la1001. You can find that over here:

Polaroid FLM 2011 Green screen


Mine did that too for a while. I called polaroid and they told me to leave it unplugged for about 10 minutes   and then plug it back in.. I did and it works fine/has ever since. Supposedly that problem is caused by a week cable signal? Try unplugging the tv to rest it before you spend money on it.

Monitor problem: screen goes black, then comes in scrambled


It sounds like this one needs component-level troubleshooting, probably in the power supply section. One or more backlights may be going out, too.
