Cool. The technician came. Unfortunately it didn't occur while he was here, so he wasn't able to see it for himself. Which sucks. However, he was able to give me a lot of useful information.
Help is still welcome/needed though. So if you have anything I'd appretiate it. Thanks.
Yo. I bought a Samsung LN46A540 model roughly 6 weeks ago. Everything seemed fine until about a week ago, where vertical lines would take over the entire screen for about 5-10 seconds, before the TV would turn itself off and then turn itself back on again. A few days ago, along with the vertical lines, it's starting to do a horifically loud, almost, screaming noise. It does this for about 5-10 seconds before switching off and then on again.
I have a TV repair man coming over right now, but you know how they can be. So, any help on the subject? Doing some research, it seems like a few Samsung models overheat pretty easily. Although I couldn't find anything about the noise, the visual lines described seems like it could be the same issue.
Anyways, vertical (white, green, purple and grey) lines, extremely loud high-pitched noise. Any help?
