Hey guys -
I made a separate post for this yesterday, but perhaps I should put it here instead since people might be subscribed to this thread.
I am currently troubleshooting my Panasonic Plasma P65VT30 TV. I have owned it about a year. I had to get the power supply board replaced not too long after buying it due to the original one failing. Ever since that time, I have had a buzz coming from the TV whenever a completely blank/black screen is shown.
After Googling around a bit, I decided to investigate the issue. I've isolated the location that the buzz comes from (and it seems to be the smaller of the two board that make up the power supply board).
What I am wondering is - Is the buzz I am hearing coming from the transformer or something else?
I am not sure if you can tell from just listening to the video or not. I am including a link here.
I did tighten a couple of screws on the board that appears to make the noise, however the noise didn't change.
Appreciate any thoughts!
