modded, will not boot, green light for 2 sec. then powers off????

I have a modded xbox I just bought. It worked for the 1st couple days but out of nowhere it started to not work. I press teh power (or even eject) and the green light comes on for like 2 seconds and then shuts off. I have disconnected all the cables and reconected them and still the same thing. I am using standard AV cables too. Any idea what the problem could be?

 

do you know if it was modded with a chip or softmod?

 

it is hardware modded solderless

 

your D0 Connector probably came loose you will have to open it up and fix it....

 

I'll check it out tonight, thanks
