Check the LVDS cable that connects its T'Con board to display panel for any loose fitting at the both end of its sockets. Re-seat them once and check. This is not a problem with any capacitors. If you wish to get more details, check the site linked here. It has screen-shots to some faulty screens to LCD TVs. Compare them to that of your TVs' and make sure. http://electronicshelponline.blogspot.com/Pull up previous posts there, either by its left side bar,
or view it in Timeslide option.
hi all .ive had the same problem,a thick black line down
screen.sometimes it flickers from top to bottom and other permantly in
view.but i have solved it.forget your ic boards and taking apart tv.have
you got either a ps3 or wii connected to tv.if so unplug power lead
from socket and relocate in seperate socket.make sure the lead is
completely free of any other leads and you might just find this works.i
think the power lead creates some sort of frequency that the tv picks up
.good luck hope it works
usually strong magnets like those in speakers cause lines on tvs if placed to close to the tv.
so demagnitizing the screen should work .
you may have to take it into a pepair shop to do this.
but if thats not the problem. you moe than likely are seeing a common problem of tv screen burn out. and these new tvs tend to burn out faster than the old ones did.
