will powerup (show red light) but wont start up (show green light)

i fixed my ylod problem by reflowing it, i know this because at 1st it started up perfectly fine like it was new. except i had to go into it again because it wasnt starting games (both in the blu ray drive and the ones i already downloaded to my harddrive) or even netflix. i figured out this was happenning because the blu ray drive ribbon wasnt connected to the motherboard.

anyways i have created a whole new problem where it will have power because it shows the red light but i cant start it neither using my controller wirelessly nor by pressing the start button. the eject button beeps(because the blu-ray isnt connected) so i know it senses that i am pressing on it so i am not sure what is causing the start up to fail.

any help or knowledge on what could cause this or what peices could be damaged would be much appreciated!
