In short I have gone to start my 360 and the power lights comes on but I don't the green ring and then the output to TV.

the is no red lights so no error code.

Starting with the eject button does the same, no xellous.

Any ideas what causing it and therefore how to fix it?

If it worked before it sounds like something came loose or disconnected from the board. I had this issue with the dbf1 spot, had to resolder 2 or 3 times..

Re-check your JTAG wires and points for any loose connection's

Checked the jtag wiring and all seemed fine.

As it is I have just removed the wires and its still the same, surely I should get a different error.

Is it possible my NAND is corrupt?

OK this is fixed. Here is how and what happened.

After switching it one and off many times I eventually gave up.

I re-soldered the jtag points and it was still the same so I reattached the lpt connections.

Firstly I just tried xellous so I could just boot into that and flash but it just didn't seem to want to work, at that point my heart dropped as I did think it was dead.

But as the nand was still willing to talk I just did a full flash from a backup over the lpt connection (lucky its a Xenon so 16mb)

Just started it up and all its working again.

Now I am interested in why it happened as I don't want to have to do this too often, but I support I am lucky to have done it myself so have the knowledge to reflash if needed.

Either way thanks to all on here as I wouldn't have fixed it (or managed to jtag it in the first place) without you all.
