Yes it is. Mine did this last year. Call Sony and they will send you a box to ship it to them. It will cost around $100 to fix, but that also includes shipping via FedEx, both ways. They were AWESOME taking care of this for me last year. I think they had it for, maybe, a week.
Others may say you can do it yourself or have someone local do it and save a few bucks, but if ANYONE other than Sony opens it, and let's say, messes it up, Sony won't touch it with a 10ft stick. No matter what you pay them.
Also, once they fix it, it comes back with a new 1 year warranty.
