Over the past few weeks I've noticed a flickering/strobing on some areas of the screen. I would post a video, but it isn't noticeable on a recording. I've done a lot of searching online and haven't found a definitive solution. I watch a lot of baseball games, and it's most noticeable when the batter is hitting. The flickering occurs along the baselines and against the backstop.

I've had the TV about 6 years now, so far the following has been replaced (main tv, used all the time):

- lamp & color wheel about 5 years ago
-processor/chip?? whatever fixed the "white dots issue", they replaced those parts.
- lamp/bulb again 14 months ago (philips bulb from amazon)

My guesses from doing some research:

-possibly could be the color wheel, even though the tv turns on fine and stays on & there's no "buzzing"
-bulb is running too hot, even though I can see the fan blowing
-bulb is starting to go, and will eventually just need to be replaced.
-or something else that i'm missing?

I'd rather not have to buy a bunch of parts without having it fix the issue...but if internet diagnosing doesn't work, I may have to pony up the $$ mad.gif

I have seen many posts here where the flickering was caused by a failing lamp, or even a new aftermarket lamp. A lamp replacement being the cheapest option, I would recommend changing the lamp before you try anything else.

I just replaced the lamp, and the same issue is still there.

This issue doesn't sound like a color wheel problem, as it never buzzes and doesn't have problems turning on ever.

I got this TV 6 years ago for about $900....so I'm hesitant to start throwing down money on more parts and not having it fix the issue.

Does anybody have a general idea on how Samsung repair places are to troubleshoot issues? A new TV may be in my future if it's too expensive to repair...

Did you replace the lamp with an OEM lamp? Aftermarket lamps are notorious for flickering and other problems.
