I can't help you but have some advice.
1. Register your TV at www.samsung.com. Why? Because in the USA Samsung was adding 3 months to the warranty for folk that did this. This doesn't appear to get it solidly back into warranty but it might help. See item 2.
2. Now get your sales date and see when it was delivered. One date is usually not the other so that adds a few days. Get your TRANSACTION NUMBER and that date you called it in. With a little luck this will be inside or exactly at the 15 month warranty and make this go a lot easier.
3. IT IS THE WEEKEND! I can't stress this enough. The rep rarely checks in so get the items above all done and if inside the 15 months try again. And try the Facebook method at the top of this forum at
I know folk don't like to do this, but extended warranties are very good ideas on expensive things.
The unit ( UN55D8000YF) turns itself off after few seconds. I bought the tv based on the review in July of 2011. We call the service number and they said it is out warranty and they send an service person on dec 20. My ticked number is 4117339260. Based on what I have read this looks like quality problem . I don't think after spending more than $2500 on the unit, I should have to pay for service as I breaks down only few months after warranty expired. Seems to me many owners have the same issue. I expected better from Samsung. Now I have to listen to my wife as why I bought a Samsung and not a Panasonic.
