Hi peeps, this is my first post. I have a UK model.
I've owned the 50 inch ST50 since July. I was starting to get concerned about this set because the picture was quite noisy. Not a problem I had with my old 42 inch PWD6 that this replaced. I've been trying to figure out for a while if this is normal, although recently I had reached the point where I knew something was not right and was planning on calling Panasonic support.
I decided to try plugging the TV directly into the wall socket, instead of into my Belkin surge protector, recently we had a printer technician fix out laser printer at work and he told me surge protectors can actually cause problems with some equipment. Well seems he was right!
All I can say is WOW, night and day difference. The picture is MUCH less noisy now. It's still not noise free, but then I live near koi ponds which have pumps running 24 hours which probably doesn't help.
Now the colours on my TV look pretty much solid, before they looked dithery and snowy. The noise is still present to some degree, but less pronounced and seems more uniform. On the color slides I'm running through white, red, green, blue all look pretty solid, the noise is more evident with gray if you look closely.
Also before when I switched on, the logo would appear and then the black would look fuzzy, like analog tv interference. This is almost non existent now.
Wish I'd figured this out before the movie I just watched Prometheus on Blu Ray. It actually looked good on "Dynamic" which is odd, because when I first used the TV dynamic looked horrible. I feel this TV does need a while to bed in. Most viewing is done with cinema or true cinema with a few minor contrast/brightness adjustments to please the eye. I also turn off most of the image processing 'enhancements' as I feel they aren't really necessary - these never made any different to the noise issue.
Q. Anyone have a "noise free" picture on their ST50?
