LN52A850 choppy picture

by reaper422 May 6, 2009 5:09AM PDT

I bought a LN52A850 a few months ago and the picture gets choppy on animated shows like family guy and south park , I see it once in a while on a normal tv show but it usually in the back ground but it?s really bad on the animated shows, It happens on DVDs but it?s not as bad . I can play a DVD of south park and it does not start chopping up till there is fast movement
Have tried all the different settings for the 120hz and watched family guy in the demo mode and it was the same with it on or off, I have reset the setting to default , same thing

Movie mode?

I found movie mode to give such artefacts and turn it off because of that. However my TV is a M range so doesn't do 100Hz+.

24Hz

Hmm, well that's not good, possibly try the following to isolate the issue.

If the player has a 24Hz option try that.
Turn off the TVs 120H processing( My TV doesn't support 100Hz+ so no idea how to do this)

Turn off edge enhancement and noise reduction.

Turn off dynamic contrast and black levels.

For your sources see if you can choose a better output mode (for instance progressive if possible)

Note for TV broadcasts the quality is variable so can have artefacts. For a DVD been played though, you shouldn't notice this, however on Family Guy Series 1 I did notice the lines where a bit blurry/odd, but apparently this is just the conversion to DVD issue.

Lastly do you have a "pure" source to test against? For instance a PS3/XBox 360 running via HDMI. That way running a game you should be able to identify if it is a processing issue by the TV or a source issue.

Thanks
I notice slight blurring trails on mine when there are areas of high contrast.
