Soooo it's been a while since I posted about my fix by the Panasonic repair shop. Guy came out did the fan fix, already knew about how to put the panel back on correctly. All my worries went out the window, this guy was OCD like me about the edges fitting into grooves correctly to avoid fractures. We checked it three times before he left.
Of course the buzz I was experiencing did not present itself at full magnitude like it was prior to him coming to see and listen for it. Of course just my luck. Anyway he tightened all the boards and applied the fan fix. Well fan noise was better (wasn't really bothersome unless room was quiet or volume low) but he did it anyway. Now I can't hear any things BUT my problem comes again with the buzzing. The buzz is still present especially with bright content, not the normal buzz plasma gets. This buzz is very distinct.
So I have two issues going on now, since I called for the fix to be inspected i now have Comcast Xfinity cable, I have the sub box, father has the DVR main box on his Plasma. His tv is 50" and mine is 60". We have a LED 60" Vizio downstairs. Some of my channels while they look great, the edges and tops of the feed have lines running down it (the top has a white line going across the top, sides have more of what seems like a feed issue.) if I put overscan "on" the lines go away, still have a faint green line that shows on light back rounds that's on every source so that's tv related, the green line isn't distinct like the lines that I'm hoping are caused by the xfinity.
Long story short the 60" Vizio also does the same issues on certain channels, I've been comparing my ZT to the Vizio (not pq wise, just to see if it happens on there too) and it also shows these lines. My guess is that the feed from xfinity for tvs larger than 50" tend to show more feed issues. It's on both my ZT and the tv downstairs (both 60") which was a sigh of relief but kind of disappointed with Comcast. The 50" plasma my dad has does not show these issues so that's why in going with tv screen size matters. More imperfections seen. Overscan On does fix this but introduces that green line down the left side with cables but this seems to be the tv more because it shows on light (gray blue green) back grounds especially gray colors, on all sources. Same thing happened with my VT60 when I had it, the ZT seems less pronounced so I'm going with this is normal for the tv (as if it is where the pixels fire from)l and do to screen size. (I know a lot of brackets and confusion in this post lol sorry doing my best to explain while at work)
So my other dilemma is should I call the repair guy and have him out new boards in the tv? I don't really wanna open this up again, as I feel I'll be trying to much and won't have that good luck this time around. Bought a sound bar which will mask it, not why I bought it tho, the ZT speakers stink. But the buzz isn't oberly annoying but can be heard from 8 ft on certain contents mostly bright or quiet scenes.
Anyway thanks again guys. Btw that green line isn't really noticeable and is only about a half of inch off the left side of the screen, right off of where that black strip is where the screen ends. Just more worried about all these vapor looking lines on the side and top of signal, looks really pixelated up close, I think other services are better but also are dishes, not good. The convenience of cable is better to me. I'm leaning towards its the feed and not the ZT
