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寸建議觀(guan)看距離為2.5m；42寸建議(yi)觀看距離為3.0m；46寸建議(yi)觀(guan)看距(ju)離為3.5m；52寸(cun)建議觀看距(ju)離為(wei)4.0m；60寸建議觀看距離(li)為4.5m。

電視機尺寸多大合適

液(ye)晶電(dian)(dian)視機(ji)常見的尺寸(cun)有32寸(cun)、42寸(cun)、46寸(cun)、47寸(cun)、50寸(cun)、60寸(cun)。如(ru)(ru)果(guo)是(shi)臥室的電(dian)(dian)視機(ji)，那么32寸(cun)、42寸(cun)是(shi)不錯的選擇。如(ru)(ru)果(guo)是(shi)放置(zhi)在客(ke)廳(ting)(ting)，客(ke)廳(ting)(ting)又不是(shi)很大，42寸(cun)、46寸(cun)、47寸(cun)的電(dian)(dian)視機(ji)就很適(shi)(shi)合(he)。如(ru)(ru)果(guo)客(ke)廳(ting)(ting)面積很大，可以選50寸(cun)的電(dian)(dian)視機(ji)。而60寸(cun)適(shi)(shi)合(he)別墅使(shi)用。

液晶電視尺寸計算方法

以(yi)(yi)32寸液晶電(dian)視機為(wei)例，其(qi)尺寸計(ji)算方法：以(yi)(yi)1 英寸= 2.539999918 厘米，以(yi)(yi)電(dian)視平(ping)面對角線計(ji)算為(wei)準(zhun)：32*2.539999918 =81.27997376厘米，按常見4:3為(wei)比例計(ji)算，一般(ban)是長=65.024cm，寬=48.768cm ；若按16:9為(wei)比例計(ji)算，一般(ban)是69=cm，寬=39cm。

電視機黑屏是怎么回事

如(ru)果電(dian)(dian)(dian)(dian)(dian)視(shi)(shi)(shi)機(ji)(ji)(ji)(ji)的(de)(de)電(dian)(dian)(dian)(dian)(dian)源指示燈滅，則可能(neng)(neng)是電(dian)(dian)(dian)(dian)(dian)視(shi)(shi)(shi)機(ji)(ji)(ji)(ji)的(de)(de)電(dian)(dian)(dian)(dian)(dian)源連接有(you)問題，導致(zhi)突然斷電(dian)(dian)(dian)(dian)(dian)黑(hei)屏。 比如(ru)電(dian)(dian)(dian)(dian)(dian)源插頭松動(dong)、電(dian)(dian)(dian)(dian)(dian)源線故(gu)(gu)(gu)障等(deng)，可以(yi)逐(zhu)一(yi)排(pai)查，找(zhao)出問題進行(xing)相應的(de)(de)處(chu)理。 如(ru)果電(dian)(dian)(dian)(dian)(dian)視(shi)(shi)(shi)機(ji)(ji)(ji)(ji)電(dian)(dian)(dian)(dian)(dian)源指示燈亮，則可能(neng)(neng)是用(yong)戶誤按(an)遙控器(qi)的(de)(de)待(dai)機(ji)(ji)(ji)(ji)鍵(jian)使電(dian)(dian)(dian)(dian)(dian)視(shi)(shi)(shi)機(ji)(ji)(ji)(ji)進入待(dai)機(ji)(ji)(ji)(ji)狀態(tai)，所以(yi)顯示黑(hei)屏，只要重新按(an)下待(dai)機(ji)(ji)(ji)(ji)鍵(jian)即可。 如(ru)果以(yi)上方法排(pai)查后(hou)，電(dian)(dian)(dian)(dian)(dian)視(shi)(shi)(shi)機(ji)(ji)(ji)(ji)仍(reng)然黑(hei)屏，有(you)可能(neng)(neng)是硬件(jian)故(gu)(gu)(gu)障引起的(de)(de)。比如(ru)電(dian)(dian)(dian)(dian)(dian)源模(mo)塊故(gu)(gu)(gu)障、開(kai)關電(dian)(dian)(dian)(dian)(dian)路短路或開(kai)路、高壓(ya)板故(gu)(gu)(gu)障、液晶屏或屏線故(gu)(gu)(gu)障、主板芯片或者其他零(ling)部(bu)件(jian)故(gu)(gu)(gu)障等(deng)，這時候需要聯系(xi)電(dian)(dian)(dian)(dian)(dian)視(shi)(shi)(shi)機(ji)(ji)(ji)(ji)的(de)(de)售后(hou)服(fu)務對(dui)電(dian)(dian)(dian)(dian)(dian)視(shi)(shi)(shi)機(ji)(ji)(ji)(ji)進行(xing)檢修(xiu)才能(neng)(neng)解(jie)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。
