It does indeed sound like a backlight problem. Generally speaking, the expense in finding a new backlight and having it fixed isn't worth it considering a new 19" monitor can be had for $150.

My dell inspirion 6000 laptop screen goes black but sometimes I can see the windows screen but it's very dark. When I attach it to a desktop monitor it works fine but the laptop is still dark. Sometime the...


The back light is the whole of the screen, the screen is illuminated by a CCFL lamp (fluro tube) on the bottom of the screen. A inverter supplies high voltage to this CCFL lamp.
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. Please click on this link and follow my instructions to identify the fault and possible fix :-

Screen goes black after 30 seconds


Yes, this is a backlight problem. However, it could be either the light itself or the inverter that powers the backlight when it fails like this. I'd recommend replacing the entire screen plus housing and hinges (it is often sold as a complete unit) or just replace the inverter (often relatively cheap) and then if that doesn't fix it replace the screen (the backlight is non-replaceably attached to the screen).

The other option is to simply attach it to an external monitor and use it like that. This is also a free way (well, as long as you know someone that has a monitor) to make absolutely sure that the problem is the screen and not anything else.

Acer laptop has developed a fully dark screen


I am assuming that you have tried switching from external monitor output and local monitor. There should be a hot key on the keyboard to switch it. Also, try looking to make sure the driver for the display is up to date. I f it was update recently try rolling the driver back. If you need help with doing any of this post a comment. Hope this has helped some.

My monitor works for a little while, then goes black.


Your power-inverter board needs an overhaul.
Probably in need of the standard capacitor replacement.
OR
a bulb in the screen is bad (a bad bulb will usually show symptoms)
It will flicker, or will look pinkishish for a bit or dark in the middle top or bottom of the screen.

Monitor stuck on black, menu buttons not responding


It's sort of a solution, but I work in a computer shop and got this screen in yesterday. I looked at it closely and it's actually the backlight that died. I pulled it apart and found that three of the 820uF/20V capacitors had swollen up. If you replace them then you should be fine, but I went for a different approach and took the inverter board from a laptop and put the in the screen and used an external power supply. It's a bit dark but it works fine now.

Panel doesnt turn on


First check all of your connections (power as well as video connections). If they are all secure, then make sure that if there are multiple inputs that you have it on the correct input (by cycling through the sources with the corresponding button). If none of that works then look carefully at your screen to see if you can make out anything on the screen. Sometimes if the LCD inverter goes out then everything is VERY dark. Hope this helps.

If the monitor was dropped, most likely you damaged the internal components that provide the picture, whether LCD or CRT. Try connecting it to another computer. If this doesn't work, check the monitor's display settings or operating system display settings for contrast or brightness. NEVER open up the monitor, because there is a high voltage capacitor that stores voltage even when the monitor is off and could kill you if it discharges.
