it is hard to comment if u dun describe better.

1. when do u get this - playback videos, netflix, astro, tv3, which box? which channel(s)?
Netflix, tv box, youtube..others not using

2. what AV mode do u use  - std, movie, dynamic, pc, gaming?
Standard, tried with dynamic, movie still same. Use for watch movie only.

3. did u go to "tools" and adjusted some of those variables?
Tried adjust few but still same

These shadows u mentioned.... not normal.
More so if u see them with different videos and inputs.

Try one last thing if u havent... go to tool, picture.... at bottom, reset the picture.
If still same, likely a hardware problem.

As above.
Can see these shadow especially in scene where background is dark. Ppl moving, then these shadow appear for like 1 second. Shadow follow the ppl movement.
