主题：【问题】关于购买大屏幕电视机 -- 夏翁
家园 这个完全在个机调节，没法比较 即便是播放的同一场球赛，如果夏普机没有调好比色的话，也一样看着不正常。
电器店里的人很少有耐心好好调节颜色，常常是很贵的电视，画面上的色彩却是稀奇古怪，甚至模糊不清 -- 这并不能归咎于电视本身不好...
家园 你搞笑吧？电视机出厂还要用户自己调色？ 我家用的是夏普的液晶电视，为了明确某个功能说明书我全都看过，里面根本没有调比色之说。
调比色在显像管电视机是存在的，但出场时是调好的，只有到日久3阴极老化不一或3种荧光粉老化不一时才需要调整各电子枪的阴极电流来保证色彩。
等离子屏从原理来说也有调色问题，但是阴极太多老化不一调不过来，只有出厂时因为荧光粉的涂层误差很大时才发生调色。
液晶是一像点上3个加红蓝绿滤光膜的液晶点同时透光，背光是白色荧光灯，滤光膜定了就无须调色，真要调色的属于印滤光膜工序出问题了（注意滤光膜是印上去的，这是日本某印刷公司的专利），属于次品，不能按设计最大限的产生色彩。
麦帅家大概用的还是显像管电视机吧？
家园 这个建议好,色彩是很重要的考虑因素
家园 好像是差个这东东：Built-In ATSC Tuner 看来那是面向北美的型号，日本没有。
google了一把，参看下面的网页。
家园 要是只差这个玩艺儿,就不用多花钱了 Built-In ATSC Tuner是用天线接收HDTV的设备,多少年没用过天线电视机了
,如果只看有线电视,应该不需要这个东东了.另外,查了一下,如果将来一定需要这玩艺儿,EXTERNAL的也不会七百块.
谢谢!
家园 KFE50A10 有数码 input 吗？ “ATSC Tuner是用天线接收HDTV“，然后直接从电视机里面把数字颜色信号在LCD上现实出来。－－KDFE50A10
如果HDTV信号是从EXTERNAL BOX来得，而电视机又没有数码 input 接头，external tuner 就是把数字信号转换成 analog 颜色信号输入电视机，看起来会差很多。－－KFE50A10
另外，KDFE50A10 里面会多一些数字技术，例如 digital cable card，是为将来直接播放数字电视做准备的。
如果你买这个电视，只用5年，KDFE50A10的很多东西也许超前了一点。
家园 具体SPECS见主贴,看不出太多不一样来 不过五年确实挺长的,说不清那时候该流行什么了......
家园 你贴的SPECS不够，need TECHNICAL data, e.g., 我估计：KFE50A10 is more analog, traditional TV; KDF-E50A10 is more digital for-future TV, or say, digital ready. SONY 网站应该有数据。下面的数据是上次我看到的PHILIPS的。

家园 BTW, 下面这个说法就当考拉是在传谣看好了。 Sony timer
不过，关于企业（组织）的伦理、道德问题也在考虑做个包子的。
刚刚在和面，啥时能蒸好就不好说了。（俺也没少挖坑呵
）
家园 最好自己到商店里看看，或者上网看看User Review. 当年我买大电视的时候，那个型号还没有User Review(在PriceGrabber)，我到商店了看看两次，觉得不错，就买了。一个星期后，写了一个Review贴了上去，不知道有没有人看，嘿嘿。
家园 比较这两种型号的REVIEW不多啊 继续找......
家园 好像唯一区别就是加了Digital Audio Out 七百刀呢，如果黎叔对于Audio要求很高的话...
家园 偶也在想没太大必要呢 但听说SEARS前个星期卖C$2299,据说是错广告,但SEARS还是照卖了......晚了一步啊
