I replaced the motherboard in my laptop and now the display just comes up white. Secondary monitor comes up just fine. If I put the old motherboard back in, the display comes up fine. I have already assumed that the new motherboard is bad so I sent it back and they sent me another one and it still just comes up with a white display. Please help

It is a HP pavilion m6-1035dx. I got the replacements from a trusted seller on ebay. They confirmed the product numbers on the motherboard just to make sure also. I just have no idea what this could be. I have been building and repairing computers for a long time and I have never run into this particular issue before.
