how bad is it ? It's V shaped right ? how far does it go into the screen ?
& can You see it at all times ?
as I have one but I can only see it when the screen is total black & that's the only time never when a signal is present, never can I see it when a movie is on even if the scene is totally dark. It only happens when the signal is not there. I can NOT even see it when my AVR a Onkyo has set-up screens that have a black edge . & I can't see it when watching a movie that has letter box aspect . the black bars across the Top/Bottom of the screen . it's in the left lower edge when I can see .. it's soo slight that if does not bother me . But when I get to the end of my warranty I just have it fixed .
BTW it's called FlashLighting as a term that is used to describe this issue.
On edgelighted LED 's it a LED that is to bright than the ones right next to the bright one . OR a dead LED as that shows up as a dark upside down cone of darkness
as your Sharp is a back lighted CFFL it's as the above poster has said a screw that is just a lttle too tight near the edge of the glass on the bezel. the larger the flashlight beam goes across the screen & If it's present during a movie then it must be way too tight .
they sometimes do not resolve by loosing the screws Soo , if your a gambling man ....
It's an easy fix some here have done themselves , BUT Really Call Sharp . Take a photo of it as they will ask you to do so . so if You do a photo in advance then your one step closer to getting the issue fixed . ( take a bunch of photo's in all different lighting & screens pick out the ones that best show the flashlighting ) DO NOT use a flash it will not show up on the photo & a cell phone usually do not work for this purpose ...
As with any Audio & Video gear these days , if something is going to fail it fails sooner than later ...
That said it's wise anytime you buy new gear is to run it Hard 24/7 for the 1st few weeks as you can return the products usually in the sellers return products due to a fault time frame . i run my new gear 24/7 for the weeks till the return policy is up . Run it hard !!!!
as they say on the Onkyo threads " Drive them like you stole them "
Of coarse this is just I M H O !!
But better safe than sorry
these are a Great Display I love mine !
anyway Good Luck . Sharp is good about service so not to worry !
but if your @ the point where it's a Big Issue !
then Take Care of the Issue now !
