LCD Screen shows only backlight/slight light after changing new screen

Okay so i ordered new lcd screen from ebay for my nikon D3000 because the original one was shattered and didn't really show anything but little bit of light. After replacing the screen the screen keeps showing black screen with backlight. It kind of turns on and blinks when taking a picture but doens't show anything. IFixit Nikon D3000 page says that it could be a motherboard problem. What do you think guys ?
