This is the second time my hp g71 358NR laptop screen has broken. The first time I had it repaired at a computer repair shop it cost me too much. This time around I thought I would take a crack at trying to repair it myself. After purchasing a replacement screen and trying to connect it to the inverter, the screen still didn't turn on. After fiddling with it for awhile, I made the mistake of trying to connect the screen with the power on. There was a itsy, tiny spark from the inverter. After that when I connected the power cord to the laptop, the lights in front of the laptop turned on, along with the light at the power cord, but when I push the start button nothing happens. I am at a lost and about to go to a repair shop if I can't fix these issues. Can someone please help?
