[QUOTE="thomas998, post: 993666, member: 111388"] Do you know it isn't the screen because the screen actually worked and you saw it after it was replaced or are you just assuming it was replaced properly the first time? It could be something as simple as the person that replaced the motherboard didn't reconnect the ribbon from the lcd panel to the video card... or didn't properly connect the video card... or didn't connect the inverter for the backlight... there are all sorts of things that might not have been reconnected properly especially when the mother board was replaced because that requires you to basically remove and disconnect everything in the notebook and then reconnect it the right way. Frankly I'm baffled you would have accepted the computer from the repairshop without making sure it worked... did you every verify that it worked? [/QUOTE]
