Because today's companies put in components that have been made as cheaply as possible for the goal of reducing cost to them therefore reducing cost to you. This is the way it is now in this global economy. If Panasonic or any other tech company didn't streamline cost, they would go out of business. I would bet, depending on manufacturing dates, components in all sets are made and distributed from different countries. Example, sets manufactured in January, may have components from Taiwan. Manufactured sets in April, may have components made in China. They just put a Panasonic stamp on it.
I am familiar with global economy manufacturing and trying to lower the bill of materials by sourcing cheaper parts during a production run. Like you noted, all manufactures do this. Often a small lowering on the bill of material can result in a significant profit increase. Regardless of where the parts come from, it is still on the OEM to ensure the quality standards remain.
This happens across the board with all products, from your everyday items like soap to the engine parts in your car. I understand your frustration. 10 years ago you probably wouldn't have had these problems as things where more focused on quality. But as I said, quality has gone by the way side. Even $50,000.00 cars break after a week of purchase. Panasonic didn't make plasma's to give you uniform appearance to the "slide break in process". That's not what they are designed to do.
I could see the edge banding during normal viewing (on light scenes) depending on the color. With some menus, the banding was pretty clear as well. I had line bleeding as well. The buzzing (mild on the first set, horrible on the second set) was very annoying. I have the TV in a room with a fish tank AND a window A/C, I could still here the buzzing over those other noises. A white commercial or bright scene would show up and it was BBBZZZ in my living room. This is a design issue, not a parts sourcing issue. Buzzing noises are a fact of life with electronics, and the offending parts can be isolated. This is also why when you open up some computer power supplies, they are covered in hot glue. The glue prevents the caps and chokes from vibrating around into an audible buzz.
They are designed for the average consumer, who do not run slides or probably even know that there is a picture settings menu. Most people want to plug, turn on, and watch. Think about it this way, if 50 people returned sets back to Panasonic, what do you think they do? They reset the hours clock, check them for quality control, repackage, then resend out. So as time goes on, you have a higher possibility that someone like you, has returned on average 2 sets per month. This equates to 100 sets per month and 1200 per year returned. Chances are greater you may get a re-manufactured set and not even know it.
They would sell them as refurbished displays or break down the parts for repair work. They don't want to get caught repackaging used panels as new and putting them back into the market for new item sales. That would be a PR disaster and violates consumer laws.
So my advice is to clearly understand what your buying, read the threads, then buy your set, give it time to settle in. If you look, most sites state after 100 hrs. of use, the set is considered aged. 200-400 hrs. is more realistic. How do we know the slides being used are created uniformly and dedicated for plasma use. We don't.
The slides are uniform. I think it is ridiculous to consider that the slides may have uniformity problems when anyone can check them in about 5 seconds using an image editor. Also I had close to ~100 hours on both TVs, much of it from video and slides.
I really don't want to return TVs. I don't even have a truck, so I need to borrow one, then load a TV into it and drive 40 minutes each way while getting about 12 MPG from the truck. And I am not trying to raise a stink about it, I was just noting that I had two other Panasonic displays with the same issue.Edited by ocellaris - 7/25/12 at 8:56am
