Just to be clear, you can still see what's on the screen, but it doesn't light up? If I understand this correctly, and this is the case, then either the screen inverter has gone out and will need replaced, or the screen back light has gone out in which you will have to replace the screen. Unfortunately, the screen is considered a sealed unit and the back light cannot be changed out. You can test the inverter with an ohm meter. Get a reading at the motherboard end, it will be a low voltage, then check the screen end. I'm not exactly sure what the voltage rating is, but it should be real close to the voltage of the wall socket you're using, and it will be considerably higher than the motherboard end. If the voltage is the same or very close at each end, ten the inverter is bad. *IMPORTANT* Be very careful when handling an inverter, they can give you quite a shock.

If your laptop appears to boot up and the hard disk LED flashes, then the problem is probably a back light fault. This can be a faulty inverter or a faulty CCFL lamp.

Perhaps a hardware problem maybe the wire tape that connects the LCD screen to the CPU in your laptop is lose connect or perhaps the worst is your laptop LCD is damaged and needs replacement.

My sreen stop working but plug to my tv an still works using another screen


If you shine a bright light at the screen and can see the picture then you may just require a ballast unit for the back light.

Compaq presario cq61 screen went dark but can still see window faintly through the dark sreen.


Look at the LCD screen very closely and check if you can see a faint image on the screen. It's possible that the LCD lid close switch stuck in the "closed" position and the back-light stays off even when you open the LCD screen or turn on the laptop. The switch turns off the back-light when you close the LCD display to save the laptop battery power.

If no luck, try to remove battery and drain the power, then replace battery and turn on.

If that didn't fix it then there are 3 things that could have gone wrong:

1. Video cable connection from inverter to LCD got loose. To check this, follow instructions from step 3 on how to open the LCD and check if cable is fitted properly.

2. The video inverter is faulty
The screen inverter failure is very similar to the back-light lamp failure. In both cases the screen gets very dark and the image on the screen becomes very faint, barely visible under a bright light. If it's still under warranty, take it for a replacement. You can replace this otherwise - you can find the inverter under the screen, follow the procedure described at point 3 to open up the screen.

3. The LCD monitor is faulty
If it works on an external monitor most likely the LCD is faulty and needs replacement. If it's still under warranty, take it for a replacement. If not, you can do it yourself, it's pretty easy. Remove the rubber covers on the side of the screen, unscrew the screws take the plastic cover off, disconnect the video inverter and put in the new LCD after you connect the video inverter to it.
