I'm currently working on a Samsung Plasma TV. Everything works with the TV except a really annoying Buzz noise coming from the power supply in the back of the TV. I ordered a new power supply and installed it in the TV. Same exact thing still. Picture and everything on TV works great, but still get an annoying buzzing that's louder than half the volume on my TV. Is there anything that could be causing the Power Supply to buzz that isn't on the power supply itself? Help is greatly appreciated here. Thanks.
