Black vertical lines randomly appreared on my LCD
I've posted some threads before about my tv and setup, I don't want to annoy anybody but I am experiencing something new :
Vertical black lines randomly appeared all over the screen, poping up and disapearing everywhere, and it was on all channels. I turned the TV off, then ON and it was ok. It was the first time I saw that... and it didn't reappeared.
I was wondering if it's only static or it's a problem on my LC52D64U Sharp ?
Thanks for your help !
