Yes power plug is very important. You can easily see 3 red light if you dont properly plug it in.
If you get 3red lights again, And Dont force the console to Turn on , Wait several minutes then try again. (Then next time wait for a longer time period )
Try without Harddrive and Xbox Live,
IF you can reach the menus you can go to
System - Console Settings - Memory -
Highlight the HDD the press Y ,
Enter X , X , LB , RB , X , X
then choose YES.
Still problems? Then Call Xbox Customer Service
