Just replaced the display on my HP pavilion laptop model 1a75dx. I have no backlight. I replaced the hard drive also. So none of the driver are installed. Also had to reseat the ram stick as I was getting a neat boot loop. But not it goes to the windows installation screen. I just have to use a flashlight to see it. My old display is all craked. But it doesn't light up either so my problem lies somewhere else. Does this laptop have an inverter that could be bad ? Also can't get an external display to work. Not sure why my guess is it's a driver issue
