Panasonic GT50 Plasma 65 in buzzing sound on bright images

by dustan9 / October 26, 2012 1:22 AM PDT

I hear a slight buzzing/humming sound from my tv on bright/white images. I have turned down the contrast and brightness and this seemed to help some. Is this normal? I have a 4 yr old Panasonic 50in thx plasma that does not make this noise.

Thank you

It's a common annoyance with many plasma TVs. If this is that bothersome, I'd consider returning it ASAP and research more about today's TVs and re-consider LCDs.

The panasonic rep came out and replaced screws on the inside panel. This is a known issue for 2011 and 2012 panasonic plasma tvs per a bulletin copy given to me by the rep. Tv is now silent on all images. Tv is outstanding and picture quality is amazing.

Hi Dustan,

I'm having the same issue but having trouble finding info on the bulletin. I haven't had the set a month yet. Did you contact Panasonic directly or a third party like Best Buy?

I'm glad to hear the issue was resolved.

I called panasonic and they sent a tech out. He gave me a copy of the bulletin.
