Flickering Problem with my brand new LN52B610 120 Hz LCD

by K-Shaun / June 23, 2009 2:11 AM PDT

Hi,
I have recently purchased the above model. Few nights ago, I was watching a movie on my digital pvr cable box on one of the HD channels and I noticed the picture flickering(pulsating). I clicked rewind on the PVR and played back the scene and it was still doing it. I also clicked info.(to get details of the movie) on the cable box remote and noticed that was flickering as well. I guess the best way I to describe it would be to say it's like your old computer monitor...when you slap the monitor on side the picture flickers almost like a spring..that's how it was but to a considerably less extent. I was say it was more of a pulse...Not sure if it's a problem with the TV or the cable. In Canada, we have "Rogers" like Verizon, comcast etc in the states. It's cable not satelitte as the signals come through cable. So I am not sure if this is a cable problem or tv problem. Although this problem hasn't happened since that night. I'd greatly appreciate some help.

Just an added to the problem reported above.

The flicker was actually more like the flicker was for a minute or two and it's more like a flicker a movie projector produces at the movie theatre. I hope this helps.

K-Shaun,

It's hard to say what causes a problem that later goes away. It could have been in the broadcast itself, or a localized issue with the cable service. If it happened at the same spot in the PVR, it may be that the data wasn't damaged. If it was happening in different spots, that indicates a different issue altogether.

Have you seen this happen with any other input?

It happened at the exact same spot as I rewound to the scene. My logic is that tv is a medium thus it only shows what's being transmitted. Sort of like a monitor on a computer. Since it happened at the same spot, wouldn't it indicate a cable issue? Since it's a brand new tv, I haven't seen it happen on other inputs. We did watch some bds however, it didn't happen until the same night when we were watching tv. If it happens in different spots, does that mean it's TV issue? My tv is connected on the hdmi/dvi input, does it matter which hdmi input it's on? Thanks again for your quick reply

You said, "If it happened at the same spot in the PVR, it may be that the data wasn't damaged." did you mean to say Data coming from cable was was damaged meaning it's a cable(cable provider) issue or did you mean that the data wasn't damaged thus making it a tv problem. Would hooking up the cable through component cables be a better option?

K-Shaun,

I meant that if a recorded show flickered in the same spot, it was leading to your point of the television being the medium.

Technically, it shouldn't matter if it's hooked up with HDMI, but if the source cuts out at the same point, its likey a source issue - that was what I was getting at. (Just to clarify)

This may not be helpful to you but I noticed some flickering on my Samsung plasma(on both Blu-ray and cable),similar to what you are describing, and it goes away when I turn off the power saving functions on the TV. May be worth a try to see if it helps.

My problem happened at a bright scene of an old movie. Mine appeared more like the kind of flicker we notice on the screen at the movie theatre so I am inclined to believe that it's likely the signal or the movie itself. What kind of flickering do you get? I haven't noticed anything on my new Samsung bluray player, although I was watching planet earth on my old sony LCD and noticed a flicker during certain scenes.

Sorry, I forgot to mention that it happened on an old movie on cable(HD PVR) on an HD Channel. Not sure if it's relevant but my HD PVR is connected with an HDMI connection to the tv and an optical cable from my home theatre to tv.

I noticed the flickering on certain scenes on Blu-ray and some HD cable broadcasts. All are hooked up via HDMI. It seems to happen mostly when there is a scene change like during a baseball game when they switch from the batter to the outfield. It is a quick flicker to white in the background of the entire TV. Like I said, it goes away when I turn off the power save function.

I will double check if the powersave feature is on or off. Do you have the same tv as me? Wanted to know if this is limited to LN52B610s. I googled the model, the tv only got glowing reviews with few minor issues and they weren't related to flickering.
