I have a HP g6-1d62nr laptop that I'm trying to replace the screen. I ordered a screen by the laptop model number and it wouldn't work. Than I ordered one from some numbers off the back of the screen. samsung ltn156at05-ho7. I installed that one and the screen comes on but it is very dim and it shakes bad! What do I need to do to get this fixed? I also read where I need to order a screen by looking at the laptop manual. Which says I need to order 639512-001 screen cause the laptop is a charcoal gray one. Would greatly appreciate any help!!
