Enjoyed Mad Max Fury road this weekend, this scene looks fantastic on the GT50 Played using HTPC w/ MPC/Madvr. Picture doesn't do justice, it looked so much better in person.

Buzzing/Hum issue isolated!

Now the buzzing cycles in loudness which is driving me crazy. I called Panasonic customer service awhile back and they said it was out of warranty so there was nothing they could do. I told them that the buzzing issue started well within the warranty but they didn't care. The 60GT50 will be the last product I'll ever buy from Panasonic. I was thinking of adding some type of sound deadening material on the wall directly behind the panel as it's mounted on the wall. Has anyone tried this or heard of anyone trying it?
After further troubleshooting I found the loud buzzing/hum that cycles on and off that gets louder when the screen has bright images is coming from my two Rythmik F12SE subs. The subs are placed on either side of my rack right below my 60GT50 so it seemed as if the hum was coming from the plasma. But when I unplugged both subs the hum was silenced. The F12SEs have torodial transformers which are noisy due to possibly getting DC offset from the plasma. If I plug the subs or the plasma into a different circuit the hum stops. It was great to finally isolate what was causing the loud and very noticeable hum .

Glad you sorted it.

I have the same combination (GT50 and single F12SE). I've never had the buzzing problem though, possibly because I have my main system plugged into a professional class 1500 VA isolation transformer consisting of:
  • TX-P50GT50B - primary monitor
  • Samsung LED display - secondary monitor
  • Dual HDMI output AVR
  • BDP
  • DVD player
... and between the Rythmik F12SE.


That's a viable alternative for those who don't have the option of a different mains circuit.
