I would recommend calling directly into 800-SAMSUNG and noting that you registered to qualify for the additional 3 months of warranty (which is offered in the U.S. only, for what I know).
Setting up a service with a live representative may allow us to assist you.
Keep me posted.
My 56" DLP TV is no longer turning on. The TV was purchased on 12/8/2008 and is barely a month past the one year warranty. I registered the product online and received the free 3-month warranty extension but when I try to put in a service request it still shows "out of warranty."
Basically I turn on the TV and the lamp light will flash for a few seconds and then the standby/temp light flashes and then it cycles back to the lamp light flashing. This continues forever until I unplug the power line.
I opened up the lamp door and tried the blue switch trick holding it down and also reseating the lamp but still no luck. I just got my dad's 46" DLP TV white/black dot issue repaired and now my 56" DLP TV is acting up! Any help is greatly appreciated!
