I'm sorry to hear that you're having this issue with your TV.
Does this happen with other inputs as well?
If so, I'd probably recommend calling the Samsung customer service center to inquire on a repair. If it's within warranty, they can set you up with a technician to repair the issue.
When I turn on my tv, the screen gets a pink tint after a few seconds, I have to turn the tv off and on about 3 times for the pink tint to go away. I've only had the tv for 6 weeks. Thought it was the directv box, but already changed that out.
