So I just bought a manufacturer refurbished motherboard for my Toshiba Satellite C875-S5975. It charges fine, boots up, but it doesn't show anything on the internal display or any external monitor I throw at it, whether its connected over RGB or HDMI. I'm thinking that the video chipset is blown or needs to be reflown but I'm not capable of doing that. I'll likely turn it in and get a replacement, but I still would like to know what the issue is with this thing. Any help is greatly appreciated!
