y'day I had spoken to Wife and got to know that generally Sony-SAB channel is more watched. Even on the day I noticed this IR, Sony-SAB was watched continuous for 2 hours - but this view itself may not be the reason for IR, and may be a reason of pile-up.
so, what I think of Sony logo, maybe Sony-SAB logo, the big S is common.
now talking on the remedial steps taken so far:
- looped on of my regular video for 2 hours continuous (I often use this earlier too - Ultimate Planet Earth from youtube)
- looped the EA images for 2 hours
- looped again this video overnight y'day
- ran one video showing colorful snowy pixels for abt 30 min
Plasma TV Logo Removing DVD - fix burn-in pixels
didnt have DVD so extracted the 16:9 vob file on pendrive, its a 10sec, so looped it.
in-between had done power-off few times and resumed play.
on more thing I noticed, in the EA solid slides, when the greens come, I could few see vertical bars (not lines), but not noticeable in other colors.
tonight will again check for IR. have asked family to watch on zoom-1.
as much that I have read, mild IR will go away by changing to dynamic content, but may take minutes to hours !
the typical problems arises due to opaque channel logo and not by translucent logo, just like TataSky HD.
