Got an 2.5 year old Bravia S series 40' 720p TV, that you can hear a bit of a weird noise from, almost sounds like screaming caps, but I'm thinking it could just be a normal invertor noise for a screen of the size. Anyone elses TV do this or does it sound more like a fault.
Thinking about it, all the PC LCD's around the place are compleatly silent when running....
I may whip the back off and check for dieing caps/dry joints. Its still under extended waranty, but they will charge if they don't find a fault.
