Hi. Last night, pretty much at this exact time, I started hearing a high pitch noise coming from my TV. It was completely random, it had been on for a few hours previous to it, it just started as I was putting a game in my PlayStation 3 (so it was in the PS3's menu). I can hear the noise whether, i'm watching Tv, playing games, whatever. I asked my mom if she could hear it and she said she couldn't hear a thing. The noise is so irratating that it get's stuck in my head for up to a few hours (depending on how long I listen to it). I just came to my dads and his TV did the same thing, only it was even higher pitch. I just got the PS3 a day before it started happening, and it first started making the noise when my PS3 was on and connected to the TV, is my PS3 like a TV killer or something? My mom said my aunt started having the same problem recently. I dont think I will be able to live with this for much longer. it is the most annoying thing I have ever heard.
