To be honest with you, I honestly dont think it was something you did when you modded it. When you mod the console, you are dealing with the nand files. Your not dealing with graphic cards. You either mod it right or you dont thus bricking it. I havent read anywhere about a bad mod causing this problem. I would say though thats its either the graphics card or something in the line of video possibly video cord itself. I just dont think you should get all uptight about it being something you caused. You said everything works fine except for that. I just dont think its something you did.
