Samsung LCD flashing/blinking like a strobe light

06-11-2011, 11:39 PM
I have a Samsung LN55C650 LCD HDTV and recently it's begun to flash/blink heavily like someone put a strobe light inside the TV. When it's happening, it happens on all inputs and all menu screens. Doesn't matter what the TV is showing. Even when I switch to an input not in use and the screen is blank/black (but the TV is on) you can still see the flashing. So maybe it's a bulb dying or a backlight issue?

I've had the problem fix itself both when the TV was on and when I've turned it off and then on a few minutes later. But it keeps coming back. I bought the TV about 16 months ago so I'm out of luck with the 1 year warranty.

I've tried switching cables, and using different power outlets. Doesn't seem to matter. Seems like an issue with the actual TV.

Any ideas what might be the problem? I've posted a short video if that helps: (remove spaces)

Also, it's a very consistent flashing. It doesn't get better or worse because of what's on the TV screen in case it might look that way in the video with the ridiculous sportscenter intro :)

Thanks for any help.

Mine too, Samsung customer service was no help. They've never heard of this problem.
It's intermitant, so eventhough I bought extended warranty, the place I bought it won't come out untill it happens 100% of the time.

Unfortunately, that appears to be the trend with Samsung customer service these days. :crying:

I have the same TV model, about 15 month old, and guess what - same problem! I am connected to Direct TV and tried changing receiver box and cables but nothing helps. NOt too sure if it is the TV or Direct TV but seeing that you too have the exact same problem - I think it is TV. Hate to call Samsung technician and spend more money :(

Hey everyone. I have a 55 inch LCD samsung series 6 and after 15 months I am getting the same thing happening. The strobe light like picture comes on and off. Has anyone figured this out? I'm going to call future shop.

Kind of highlights the value of an extended warranty.
