3 problems on one xbox

[shaky]

i have an xbox 360 with no sound , no picture and the controler will not conect to the xbox there are no red lights on the xbox everything is fine just no pic or sound

all you can do is try all the stuff
power supply
audio/video cable
i would try a different tv also

tried a different tv mate and leads do you think it would solve all three probs if i done an xclamp fix

[tonyuk73]

could be a dry joint on the mother board where the av lead plugs in at the socket at the back of the xbox...just a guess.
(x-clamp fix but you are not showing any errors.)

it should be showing you a error of some kind.
there is now way i would xclamp till i saw a error

do this hook it up to a tv, every thing just like its supposed to be
and turn it on
then after the green lights go around (they do right)
unplug the video cable and see what it does

no mate no errors but i have had them before with no picture only sound some times that is how it starts if you leave it it goes to three red lights , should i just try try heating the board up then first and try that

[CoFree]

ok
so if you leave it going it will error out then
yea a xclamp maybe your best bet
i would not over heat the console
ive never been a big fan of that
also i would let it red ring and get the error code

The specific type of hardware failure can be determined by a "hidden" error code

* Turn the xbox 360 on, and wait till the 3 red lights are flashing.
* Press and hold the sync up button (the small white one), while holding that button press the eject button.
* The LEDs will now blink the first number in the code (as described below).
* Release the eject button and press it again.
* The LEDs will now blink the second number of the code.
* Release the eject button and press it again.
* The LEDs will now blink the third number of the code.
* Release the eject button and press it again.
* The LEDs will now blink the forth number of the code.
* Release the eject button and press it again.
* The LEDs will go back to the 3 red flashing lights.

You should be able to determine the difference between the 3 flashing lights and the error code lights by the rate in which they flash.
