So yea, this bitch of mine is killing me. I did the x-clamp fix every time it would give me 3 rrod or no picture at all. This time around, I simply loosened the screws and let it overheat cause I got lazy and didn't want to apply new thermal past (which was 2 days ago). This is where I believe I put my EE major to shame:

I put put laid the xbox mobo on the casing and turned it on. Well, it turned on by itself..probably from shorting itself, and then I unplugged it. Next thing, I get one blinking light, turning immediately into 3. So I turn it off and back on again and now I am stuck with 1 blinking light and error 73.

So it is either in due to me loosening the GPU screws a lot, or SS itself somewhere...what do you all think?

also secondary error is 1022, which means it's the A/V cable (probably not) or the scalar chip(shit)

E73 is not the A/V chip...
Here you go -> E73

yea, I'm gonna see how this goes tommorw..I will let you know how it happens. Thanks man.
