I have one of my bosses 360's and it has a strange issue. No red lights on the ROL. When you press the power button, either on the controller or the console, it will do one of 2 things.
A. It'll act like it's going to boot as normal... screen flickers when the video kicks in but you never see anything but black... also the audio only lasts about a second. Everything seems to be booting fine though... the ROL goes through it's process... you just never see or hear anything.
B. This doesn't happen often but enough to mention considering it shouldn't be happening at all. When the power button is pressed the green center light on the ROL comes on but that's it... no other signs of a proper boot.
What's been tried thus far? 3 different power bricks and I think 6 different sets of video cables... both VGA and and standard RCA.
I've never seen any RED LIGHTS but I don't know how the console was behaving prior to me getting it... everyone at the owners house is playing dumb.
