I have a 1.6 XBox which I modded some time ago with a Duo X2 GS (blue PCB) chip.

Today I turned on the XBox, and there was no audio or video at all, but the red light from the mod chip was still flashing as usual.

I tried booting to the Microsoft dash (turn on using eject button), and it worked fine.

I tried the on button again, but there was still no picture or sound.

What should I do? I remember seeing a thread where someone was having a similar issue - he fixed it by switching the chip to it's second bank, and then flashing it with the 1.6 BIOS. I tried booting the XBox with bank 1, but there was no A/V, and the light on the front of the XBox was flashing green and orange.

it sounds like your evoxM8(1.6) bios bank has become corrupted.
the other bank does not have a 1.6 compatable BIOS.

in short, you need to flash both banks of the chip with a 1.6 compatable BIOS image, but you can't do it with a 1.6 xbox.

other option...buy another chip.
