電視行業簡介

電視機尺寸與觀看距離

32寸建議觀看距離為2.3m；39寸(cun)建議(yi)觀看距離為2.5m；42寸建議(yi)觀看距離為(wei)3.0m；46寸(cun)建議觀看距離為3.5m；52寸建(jian)議(yi)觀(guan)看(kan)距離為4.0m；60寸建議觀看(kan)距(ju)離為4.5m。

電視機尺寸多大合適

液晶電(dian)(dian)視機常見的(de)尺寸(cun)(cun)(cun)(cun)(cun)有(you)32寸(cun)(cun)(cun)(cun)(cun)、42寸(cun)(cun)(cun)(cun)(cun)、46寸(cun)(cun)(cun)(cun)(cun)、47寸(cun)(cun)(cun)(cun)(cun)、50寸(cun)(cun)(cun)(cun)(cun)、60寸(cun)(cun)(cun)(cun)(cun)。如果(guo)是(shi)臥室的(de)電(dian)(dian)視機，那(nei)么32寸(cun)(cun)(cun)(cun)(cun)、42寸(cun)(cun)(cun)(cun)(cun)是(shi)不錯的(de)選擇。如果(guo)是(shi)放置在客(ke)廳(ting)，客(ke)廳(ting)又不是(shi)很(hen)(hen)大(da)，42寸(cun)(cun)(cun)(cun)(cun)、46寸(cun)(cun)(cun)(cun)(cun)、47寸(cun)(cun)(cun)(cun)(cun)的(de)電(dian)(dian)視機就(jiu)很(hen)(hen)適(shi)合。如果(guo)客(ke)廳(ting)面積很(hen)(hen)大(da)，可(ke)以選50寸(cun)(cun)(cun)(cun)(cun)的(de)電(dian)(dian)視機。而60寸(cun)(cun)(cun)(cun)(cun)適(shi)合別墅使(shi)用(yong)。

液晶電視尺寸計算方法

以(yi)32寸液(ye)晶(jing)電視(shi)機為例(li)，其尺寸計算(suan)方法：以(yi)1 英寸= 2.539999918 厘(li)米，以(yi)電視(shi)平面對角線(xian)計算(suan)為準(zhun)：32*2.539999918 =81.27997376厘(li)米，按常見4:3為比(bi)例(li)計算(suan)，一般是長=65.024cm，寬=48.768cm ；若(ruo)按16:9為比(bi)例(li)計算(suan)，一般是69=cm，寬=39cm。

電視機黑屏是怎么回事

如果(guo)電(dian)(dian)(dian)(dian)(dian)視(shi)(shi)(shi)(shi)機的電(dian)(dian)(dian)(dian)(dian)源(yuan)指示(shi)燈(deng)滅，則可(ke)能(neng)是電(dian)(dian)(dian)(dian)(dian)視(shi)(shi)(shi)(shi)機的電(dian)(dian)(dian)(dian)(dian)源(yuan)連接(jie)有問題，導(dao)致突然斷電(dian)(dian)(dian)(dian)(dian)黑(hei)屏。 比如電(dian)(dian)(dian)(dian)(dian)源(yuan)插頭松動、電(dian)(dian)(dian)(dian)(dian)源(yuan)線故(gu)障(zhang)(zhang)等(deng)，可(ke)以逐一(yi)排查(cha)，找出(chu)問題進行(xing)(xing)相應的處理。 如果(guo)電(dian)(dian)(dian)(dian)(dian)視(shi)(shi)(shi)(shi)機電(dian)(dian)(dian)(dian)(dian)源(yuan)指示(shi)燈(deng)亮，則可(ke)能(neng)是用戶誤按遙控器的待(dai)機鍵(jian)使電(dian)(dian)(dian)(dian)(dian)視(shi)(shi)(shi)(shi)機進入待(dai)機狀(zhuang)態(tai)，所以顯(xian)示(shi)黑(hei)屏，只要重新按下待(dai)機鍵(jian)即可(ke)。 如果(guo)以上方法排查(cha)后(hou)，電(dian)(dian)(dian)(dian)(dian)視(shi)(shi)(shi)(shi)機仍然黑(hei)屏，有可(ke)能(neng)是硬(ying)件(jian)(jian)故(gu)障(zhang)(zhang)引(yin)起(qi)的。比如電(dian)(dian)(dian)(dian)(dian)源(yuan)模塊故(gu)障(zhang)(zhang)、開關電(dian)(dian)(dian)(dian)(dian)路(lu)短路(lu)或開路(lu)、高壓板故(gu)障(zhang)(zhang)、液晶(jing)屏或屏線故(gu)障(zhang)(zhang)、主板芯(xin)片或者其他零(ling)部件(jian)(jian)故(gu)障(zhang)(zhang)等(deng)，這(zhe)時候(hou)需(xu)要聯系(xi)電(dian)(dian)(dian)(dian)(dian)視(shi)(shi)(shi)(shi)機的售后(hou)服(fu)務對(dui)電(dian)(dian)(dian)(dian)(dian)視(shi)(shi)(shi)(shi)機進行(xing)(xing)檢修才(cai)能(neng)解決。

市場上電視機品牌眾多，消費者應擦亮眼睛，選購合格有質量保障的產品才是明智選擇。
