【曝光】松下PDP设计缺陷 短时间内屏幕变灰 - 已引起CNET关注。附带真相！

抢手枪手

看来日本制造确实是在走下坡路啊……只有AV事业蒸蒸日上，这点我裆中央还是满意的。

engadget也报道该问题了

如果我摆了这么多事实都算是“忽悠”的话，那我不知道什么不叫忽悠了.........

最新的报道是松下官方已经承认了这一问题，并解释为“自动增加电压以达到完美的画质”。不过看来消费者对于松下的官方解释普遍认为是扯淡！有个哥们儿还向老板推荐买了一台，并表示出相当的担忧——真可怜！[s:14]

Sammy Sosa一词确实很经典！[s:20]

参考翻译：10年2月4日松下对该问题的官方回应：
“使用期内的自动对比度调整”
    松下Viera等离子电视机在其使用期间提供出众的画质表现。所有显示设备的元件和材料特性会在使用过程中发生改变。为了让产品在整个使用期内达到最佳的画面效果，松下Viera等离子电视使用了一种自动控制，它按照预先设定的使用间隔期调整内部驱动电压。
    这种自动电压调整的结果是，背景亮度会比初始值增加。经过几年的正常（原文Typical）使用，内部材料特性将会稳定，也不再需要额外的电压调整。在这个稳定点上的黑位就会产生极佳的图像效果。
    最新的Viera等离子电视使用了改进的自动控制，电压调整幅度更小。这导致黑位随着时间的变化更缓慢了。

原文：
Panasonic's Official Response to the Issue as of 2/4/10

"Automatic Control of Contrast over Operational Lifetime."

Panasonic Viera plasma HDTVs deliver exceptional picture performance throughout the lifetime of these products. Various elements and material characteristics of all electronic displays change with use over time. In order to achieve the optimal picture performance throughout the life of the set, Panasonic Viera plasma HDTVs incorporate an automatic control which adjusts an internal driving voltage at predetermined intervals of operational hours.

As a result of this automatic voltage adjustment, background brightness will increase from its initial value. After several years of typical use, the internal material characteristics will stabilize and no additional automatic voltage adjustments are required. The Black Level at this stabilized point will yield excellent picture performance.

The newest Viera plasma HDTVs incorporate an improved automatic control which applies the voltage adjustments in smaller increments. This results in a more gradual change in the Black Level over time."

请给个原文档链接，谢谢。

大家都还没搞清楚是怎么回事，回帖就17页了，有意思。

另外就是，原来国外也有枪手的。

是啊，然后国内的L枪们把一个国外论坛上的讨论帖当成“真相” 说成是官方结论发上来……

shannon_chen

翻译不准，最后一句应该是“这导致黑位随着时间的变化更缓慢了”。原文已更正。

其实这个也是国外很多专业网站上在质疑的问题。瘾科技，cnet都在说。当然，他们都是媒体而已。

您受累把后面这段也翻了吧！

Especially considering many buyers purchased their televisions specifically for those deep black levels, you can see why a TV suddenly going Sammy Sosa overnight would be upsetting. One of the reigning theories in the thread indicated by poster & calibrator D-Nice has been that this is by design, but a flaw in the settings caused the large jumps (around double the brightness, as measured by several owners light meters) instead of a much more subtle change. So what now for owners or potential buyers? Without more details about what is going on and whether or not anything can be done about it, like CNET's David Katzmeier, it's hard to see how we can continue to recommend these HDTVs for purchase without knowing what they will do months or years down the line. The ball is in Panasonic's court now, a speedy response could do a lot to assuage the concerns of current and potential owners.

大能的雨总果然出现在这里，这个帖子里面的问题麻烦您老解释下？呼唤了雨总好几天，雨总是N次过门而不入啊，雨总，无数崇拜您的网友还等着您指点迷津呢 [s:108]   http://www.jd-bbs.com/viewthread.php?tid=2179952&extra=&page=2

不是合资，而是松下收购了三洋超过50%的股份。美国联邦贸易委员会和中国商务部都只是“有条件同意收购”，也就是双方的收购要在一定框架范围内，保持品牌独立，并保证包括在华三洋投资企业的独立经营自主和独立。

您翻译的那段是松下在2月4日回复CNET的官方解释，Engadget对于此事的报道和松下用户的回复全文在下面的链接：

Panasonic cops to rising black levels in its plasma HDTVs, but questions still remain
Over the last several months complaints that Panasonic's plasma HDTVs experience sudden adverse changes in their black levels after a certain number of viewing hours have been piling up in an AVSForum thread, and now that behavior has been confirmed, though not very well explained, in a response the company sent to CNET today:

In order to achieve the optimal picture performance throughout the life of the set, Panasonic Viera plasma HDTVs incorporate an automatic control which adjusts an internal driving voltage at predetermined intervals of operational hours. As a result of this automatic voltage adjustment, background brightness will increase from its initial value ... The newest Viera plasma HDTVs incorporate an improved automatic control which applies the voltage adjustments in smaller increments. This results in a more gradual change in the Black Level over time.

建议您把上面的报道翻译完全才更加客观！
