I have not changed anything or moved any of the "electronics" around the Xbox to cause this to start happening. But I will try some "isolation" to see if that does correct this.
Could a "power supply on its way out" be doing this?
Is there a way to "diagnose / test" the power supply?
I have not done any mods to the shielding in the box and the only thing near it is the Pelican system selector Pro it is sitting on. The Xbox has been sitting on this selector since "day one" and I have not had any problems with it, but thinking about what you had said I'll try moving it, Thanks
