Black screen HP Compaq Presario CQ56

My notebook doesn't work. After shutdown it doesn't start. There is no operation on screen from bios/ cmos. screen is still being black. Furthermore the cooler doesn't run. Power supply, akkumulator and ram are ok...I've tested the voltage and also tested the ram in another notebook. Status Led is blue = ok. In the end there isn't a function. I suppose the powerboard has a defect. But what can i measure with the voltmeter? Maybe you have an idea? Sorry for my diction i'm from Germany. thanks...

Black display after start up notebook HP Compaq Presario


This may be the motherboard has failed, it happens more than most people think. There is no way to check it, but if you are advanced enough you can buy one and replace it, and not have to worry about reinstalling your operating system. Just a possibility, but that is what it sounds like to me.

The screen on my compaq presario cq56 is black


The problem is caused by the inverter board, "just below the screen" is more than likely the problem, or it is the backlight behind the LCD display, "built in" less likely.
