I have had my 60PK950 since they released and it's now that suddenly I get a loud unnormal buzzing from the set, mostly from the left upper back when facing the set from the front. I noticed that sometimes now it gets louder when a screen is bright or is majority white, but it chills when it's dark or mostly black. Sometimes I hear nothing unless I go behind it and focus on it, which is normal from my experience. When I put my hand over the left back or turn the tv slightly left and right and back to center the loud buzzing seems to go to normal.
Anyhow, does anyone have an idea what is actually going on or how I can address it? I find this odd and I fear that my tv might be close to suddenly becoming a loud buzzing annoyance or crap out on me. Normally I wouldn't be so bothered because it would just mean upgrade time, but money isn't falling off trees of late.
Thank you in advance to any and all who chime in.
