It has 2 year warranty. I took mine for repair after almost a year and was worry about that but they confirmed it was 2 years. Just so you know, you have to pay the shipping to send it to the repair shop (they will send it to your address at no charge). They are located in NJ so if you are from the area you can drop it off yourself (I did).
Michael, I have 5 Onykos and wish the older ones would develop a problem so I could upgrade them for newer ones. These will not break and mine get a lot of use as all my TV's run through them ... so they can get hours a day, every day.
