I have already read of things like this on Beyond a few times, and have pretty much already told the kid to pound sand, but just for kicks, I want to see what the general consensus is.
Scenario is this.
Wife and I wanted KINECT, thought it might be fun. I wanted one of the new Xboxs because of the new looks and being so quiet. Costco was selling the Kinect kit and 360 bundle. Wife told me that I had to get rid of the old xbox before buying the new one. Not a big deal, I put it up on a few websites including Kijiji.
I had a guy off Kijiji come to my house to buy it. I started it up, had it hooked up to my TV via HDMI and showed it to him playing black ops just fine. I sold him the console with a 120gb HDD for $125. He then asked for a controller, so I provided him with a wireless controller with charge kit and rechargeable battery for an extra $25. I Demo'd everything for him, everything was working fine, ZERO issues.
I just got a call from him 2 days later. He wants to return it to me as there is a hardware failure. Apparently the device is showing E74 and the bottom right 1/4 of the ring is flashing red. Never once in the year I have owned it has it done this. Never once has this xbox given me any grief.
I don't know what this kid has done to the xbox, and it is 2 days later, and he told me on the phone that up until now it was working fine for him too, it just started. Now he is threatening me that he knows where I live, and will show up at my door with the CPS and that both of his parents are lawyers and he will take me to court as there is no way I didn't know about this. To which I replied "I look forward to it".
I don't think he understands that if I had known something was wrong with it, I would not have had him come to my house so I could demo it. but either way, I am just shaking my head.
