so i use the AV cable and 150W power cable. Xbox was manufactured May 2009. Whenever I try to turn it on, it makes a weird sound for 2 seconds, and on the tv screen, it shows the loading screen for 2 seconds and then it just turns black. any ideas what can be wrong? loose wire?
already tried a different power brick, same result. also, when the av cable isn't plugged into the xbox, it's not giving me the red rings, the xbox power logo is just green.
it was working fine, and then i modded it and it turned like this. possibly bad firmware? and it's a liteon drive. does that mean i can't revert back to original firmware? if so, any ideas what i can do?
