Default Troubleshoot for Laptop LCD screen was dark (Bad inverter )

Warning: Please make sure that the laptop is not connecting to any power source including the battery and the AC adapter.
The Laptop LCD Screen
The Laptop LCD Screen is one of the most important (also expensive) parts for the Laptop. The LCD Screen itself has several components. There are several ways to identify which component is defective.
Problem: Laptop LCD screen was dark.
Solve: plug the laptop to an external monitor. If the external monitor displays normally, then the problem is from one of these components: LCD backlight, laptop inverter, LCD cable or video board. Further tests have to be conducted to verify the particular component.
First open the LCD to test the Laptop inverter, connect to a separate LCD back light (can purchase from www.computercare.ca), turn the computer on; if the backlight lights up, then the inverter is highly unlikely defective.

i worked at the computer lab on my campus for a while and all the Dell LCDs had at least 3 deadpixels on them.

the iPad follows our posture - it is so intuitive. Great comments! Thanks

All of this information is well and good Ernie, but I've looked over all your blog entries visible without going to archives and it seems every one is either 100% about the computer. I understand Think of the backlight as a thin fluorescent tubelight that powers up the monitor screen. Most backlight bulbs have a lifespan of 3, 5 or 7 years but you might notice the screen go dim & dark as early as 2-3 years.

Thank you for this information. I am having issues with my laptop monitor. Most of the time it is very dark, and occasionally it lights up. It seems to make sense to me that it could very well be the back light. I am not sure that I am confident enough to attempt to repair it myself, so I am thinking about taking it to a repair shop. I think it would be much safer for me to do so. Does anyone know of a good place to find a good repair shop? 613-742-7233 Thank.
