causing it? I got a 32'' LCD TV by Sony in July. By mid-August the TV was producing a high pitched squeal or whine after being on for just 30 minutes. I called warranty repair, and the man replaced the power supply in the unit. About a day later, the noise has returned. What could possibly be causing this in a 2 month old TV?
