I came across this forum while trying to find a fix for some issues I am having with two XBox Slims that I own.
This XBox I purchased from Craigslist very cheap, knowing that it wouldn't power on. I've taken the console apart to look for any obvious issues, but none were found. The problem is that when plugged in, it makes the correct beeping sounds (disc eject and power button) but no lights come on. I have tested it on a known working power brick, tried to turn it on with and without HDMI connected. I also have swapped the ROL/RF module between XBoxs along with the front panel with the ribbon connector. The issue still persists.
I haven't really read any threads pertaining to this issue that had any answers. I saw a few on the XBox forum but all of their 'ambassadors' give a few cookie cutter steps to troubleshoot and then recommend calling Microsoft for repair.
Has anyone had the same issue and found a fix for it? Thanks for your time!
