I feel stupid now. When the client brought it in, the first thing we asked was whether or not the unit was under warranty. He said "no, I only had a one year warranty". I took him for his word and never thought to check if it was still in warranty. He'll be getting a call with his options (sending it in for repair). Never again will I take a client's word for warranty. The last thing I need is someone coming in for a repair, bill them, and then get an angry phone call from the customer asking us why they were charged for something that was under warranty. I'm re-assembling and giving it back to the client. Thanks everyone.
