i just got done soldering and installing and i checked all my point with a meter... all seem fine so i go to boot and my xbox turns on for a second then shuts off.. same thing 2 more times then it stays on and shows nothing on the screen.... have been trying to figure out whats wrong.. i had a 2.2 pro with solderless and it would do the same thing but it was because of the solder less and the do... so now im stumped as to what is wrong.. thought i would go to the source of my chip with my problem.
