MacBook A1342 not displaying color red, but displays as black

So recently I have replaced my A1342's screen assembly, and noticed that there is a issue with the colors. It doesn't display the color red, and has this pretty weird blue tint over it. At first I thought this would just be a LCD issue, and then I replaced the LCD. Issue did not resolve. Before I had changed the LCD itself, I have replaced the logic board with the 2010 variant of the A1342 motherboard, which is the 2.4ghz and the Nvidia 320m. Now at first you would be thinking this is a gpu issue, and I know for a fact it's not. I tested with the external display and all the colors display normally. I have also tested all software issues, accesbilties, display, filters, etc. And I assure you that it's not a software issue. I am thinking its a hardware issue, but I am not quite sure which it could be. Is it the LVDS cable? Is it the logic board's LVDS port? Please let me know what you think it may be, and I will also attach a few photos to show.
