Back in the day of CRTs we had to explain this to new TV owners. Even today there can be some warm up period. BUT THIS IS NOT YOUR ISSUE. I would have not used the word FUZZY in your title but use WHITE LINES ON PICTURE AT STARTUP.
--> I have a suggestion. Go to SAMSUNG.COM and register your set. If you do this you might get 3 more months of warranty. Then you can call 1-800-SAMSUNG to begin the process.
I have a Samsung LN52A650 LCD tv. About four months after the warranty expired (naturally) I started noticing that when you firt power up the tv in the morning, or after a long time being off, the picture is fuzzy - white lines running through about 70% of the screen. After the tv has been on for about 10-15 minutes, it goes away and the picture is great. Of course, Samsung customer service has never heard of this, aand all they suggest is take it to an authorized service center, where they will gladly look at it for $99. Anyone have a similar problem, and can you share your results? Thanks.
