There are two thin dark lines down the right side of my tv, they recently appeared and are most noticeable on football fields... Its quite annoying.. its about 9-10 months old

Claim against warranty until its too late!!!

my tv is HYUNDAI HQL260WR

you can barely see the two lines on blue, but are most notable on green and sometimes red... They're not totally black, but its as if the brightness in those areas is less than the rest of the screen.
