When you say that there is a fraggy noise coming from the left side of the laptop, where exactly, and I do mean exactly where is the noise comming from? If it is coming from the lower corner of the LCD screen, then it is a bad connection on your backlight causing an overload to your inverter, and then the inverter shuts down like it is supposed to do in order to avoid a burn-up. Please repost with an exact location of the noise, as this is where the troubled component is.

Hi All,

I have a Dell Inspiron 9200 and have also been having an issue with my screen going black. When I start the laptop, the Dell and Windows screen appears as normal for a quick second each, and then the screen turns black (but is barely visible when shining a flashlight on it). I've hooked it up to my TV so I can run programs and that works fine. However, I'd like to be able to use it as a mobile laptop again. Any suggestions??

I know exactly what is wrong with your laptop. It is a defective inverter board. Just go onto ebay and find a replacement one cheap. You have to take off the display bezel to get access to the inverter board but once you replace that your problem will be solved. You can find a service manual on google for your exact model laptop to see how to disassemble the screen to get access to the inverter board.

I think you have to check your laptop charger.May be over charged or some defect in it,it would effect to your laptop screen.
My friend faced this kind of problem that's why i am sharing this one here.
