When I first got a Jasper unit, it red-ringed after a few days, but I noticed that the light on the PSU was red, so I borrowed a PSU off a friend and everything was fine. There was nothing wrong with the console itself. MS sent me a new PSU and I've had no problems ever since. Chances are, if it's not an issue with the power strip, it's probably a faulty PSU.
The guy could try checking the secondary error code (if that's still possible with the new 360s). When I did that, it was 0003, which (usually) means that the console isn't getting clean power from the power supply.
