Question about HP Compaq nx7010 Notebook
Usually when you don't see the display the problem will be the backlight system not the display hardware.
You can easily check what the problem is by a few simple tests. First turn the laptop on and look for a ghost like or faded image. You may have to get fairly close or off to the side or both before you can see it. If it looks like your normal desktop (you may even see the mouse cursor move) then the problem is the backlight or the backlight power board. Usually the power or inverter board.
If you don't see anything we want to find out if it is the video section or the display. To do this we need to connect an external monitor. The monitor should be automatically detected and show an image but you may need to swtich using the function key method. FN plus one of the F keys will switch or enable the displays.. If you see something here but cannot detect that ghost image it indicates the lcd is the problem. If you do see both the ghost and the desktop on the external that confirms backlighting. If you do not see either ghost or external image then you have a video hardware failure.
You can replace the backlight for about $60 on average plus labour. The lcd screen will be over $200 and up. And if the video section is gone then the only fix for that is replacing the mainboard. The video section is part of the main computer board not a seperate thing.
At this point you need to check if you have any warrenty store or factory. This would be covered regardless of what the problem is. You may want to search around for a repair shop and check prices for parts and labour assuming it is the backlight. If it is the backlight it is worth fixing. If it is the video section then you may spend about or just about the same as buying a new laptop to get it fixed.
