My xbox 360 was working fine and then I went to play it and it doesn't show anything or have sound I tried replacing the av cables and using different tvs but still nothing it had a green ring no red ring

Try different AV ports on the TV, if it doesn't work press the right trigger + Y, right after the console starts (this will reset the resolution of the console output) I'm assuming you are using the same cable that worked with another TV, so neither the cable is broken, neither the Xbox. It can only be an output format problem, bad configured or a faulty TV.

try it in another tv with av cable
if u are using hdmi cable try changing the existing cable

if it works in another tv , go changing the setting in the displaysettings and video settiing

What kind of cables are you using? What are the colors of the cables?
Have you tried your friends AV cables?
How many more discs experiences this?

- Try your friend's xbox360 console's settings to your console.

to start off,what type of cable are you using??
since you've already tried using 2diff TVs,basically its with the console

try using a different AV CABLES, if it still doesnt work,try calling xbox support hotline for possible replacement of your cable or for processing a repair for the xbox if necessary..

since you just bought your console,try going back to the store where you bought it and have it replaced, because for the repalcement of the cable if you call xbox support,it will take 8-12business days for toureceive it and 2-3weeks for the turn around time of the repair for the xbox.

E74: AV cable error... There is a problem with the AV cable, try using a different AV cable. If the cable is known to be working then there is a 90% chance it's a scaler chip problem (the "ANA" or "HANA" chip connected directly to the AV cable) in rare cases it is the GPU.

If you nave a good AV cord, this will be a chip issue. you will have to call Microsoft in this case for a repair ticket.

If you have not ever opened the console for any reason, you can call this number for a free repair.

Follow the steps below, Hope this helps

1. Try another Av cable ( Audio video Cable )

2. Try another television

3. If the steps dont work, call xbox customer support to have your xbox serviced. Good Luck! hope your console still has warranty

The main reason why its acting that way its possible that the AV PORT is faulty or its your cables..

try using the standard av cables, if that doesn't work then it's most likely a gpu hardware failure. call 1-800-4MY-XBOXand the can help.

It is the solder under the GPU chip. Same as the 3 red light problem. YOu can send it to us if you want it fixed.

hi MC, power off unit unplug av cable from back of xbox.. then power up unit.. after a couple minutes the xbox will shut down.. plug the av cable back in and power up.. Good Luck

where you put the cables for the sound and picture if you look on the end where you plug it into the xbox 360 you will see a little switch it has HD and TV on it depending on what your tv supports (HD ready TV) (normal TV) switch that switch to what TV you have (e.g. HD TV, switch the switch to HD) if that doesnt work then try checking that you have all the cables in the right ports if you have pluged the HD cables into a normal TV then this is not going to work, check cables and check the switch!
