Faulty 360, can i fix it?

[dovey]

I'm pretty new to consoles and have managed to blag a first gen 360 off a friend who was given it by a friend and never used it.

I managed to get it hooked up and working after a lot of messing about with different inputs and such. However soon after getting a game going (pes) the colours go very weird, it is as if the console has just switched to 8bit colour instead of 32bit. I stuck a dvd on and everything was fine, this is running through component at 1080p.

After restarting the console it is showing one green light but displaying no video (audio is there). I assume something has gone badly wrong but it does not have any red rings which I thought they displayed when a hardware fault had occurred?

I'm not too fussed about it as it was free but if there are any legitimate/working tricks that anyone knows of to get it going again i'm willing to give it a go!

Thanks

Thanks for the suggestions guys. I was running it in 1080p over a nec 24wmgx3, when there was no video output i used Y+r trigger to reset the video settings and was trying to use the standard video cable instead of component. I also tried another tv which also detected no signal.

I don't have a heatgun so i might search around and give the oven trick/x clamp a go as a lot of you have suggested
