Question about Hitachi P50H401 50 in. Plasma HDTV
The TV is about 1 1/2 years old and the buzzing/humming sound has become quite noticeable. It does not change when you adjust the volume (it's the same even if the volume is muted).
I think you have problem with the main digital PWB
You need change that part.
