Thanks guys; For now i'got this Vizio Running i did the BGA chip heating, i don't know for how long,
i applied the same method as the Ps3 YLOD fix tutorial just by heating first bottom side with low heat then with high heat the heat sink , let it cool for an hour then put it together and voila it's running for now,i opened a big hole behind the Main board Heat sink and added 2 small 5 v fans connected to USB.
