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

電視機尺寸多大合適

液晶電(dian)(dian)(dian)視機(ji)常(chang)見的尺(chi)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)。如果是(shi)臥室的電(dian)(dian)(dian)視機(ji)，那么32寸(cun)(cun)(cun)(cun)(cun)、42寸(cun)(cun)(cun)(cun)(cun)是(shi)不(bu)錯的選(xuan)擇(ze)。如果是(shi)放(fang)置在客廳，客廳又不(bu)是(shi)很(hen)(hen)大，42寸(cun)(cun)(cun)(cun)(cun)、46寸(cun)(cun)(cun)(cun)(cun)、47寸(cun)(cun)(cun)(cun)(cun)的電(dian)(dian)(dian)視機(ji)就(jiu)很(hen)(hen)適合。如果客廳面(mian)積很(hen)(hen)大，可以選(xuan)50寸(cun)(cun)(cun)(cun)(cun)的電(dian)(dian)(dian)視機(ji)。而60寸(cun)(cun)(cun)(cun)(cun)適合別墅(shu)使(shi)用。

液晶電視尺寸計算方法

以(yi)32寸(cun)液(ye)晶(jing)電視機(ji)為例，其(qi)尺(chi)寸(cun)計算(suan)方法(fa)：以(yi)1 英寸(cun)= 2.539999918 厘(li)米，以(yi)電視平面(mian)對(dui)角(jiao)線(xian)計算(suan)為準(zhun)：32*2.539999918 =81.27997376厘(li)米，按常見4:3為比(bi)例計算(suan)，一般是長(chang)=65.024cm，寬=48.768cm ；若按16:9為比(bi)例計算(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)視(shi)(shi)機(ji)(ji)(ji)的電(dian)(dian)(dian)(dian)源指(zhi)示(shi)燈滅，則(ze)可(ke)(ke)能(neng)(neng)是電(dian)(dian)(dian)(dian)視(shi)(shi)機(ji)(ji)(ji)的電(dian)(dian)(dian)(dian)源連接有問題(ti)，導(dao)致突然斷(duan)電(dian)(dian)(dian)(dian)黑屏。 比如電(dian)(dian)(dian)(dian)源插頭松動、電(dian)(dian)(dian)(dian)源線故(gu)(gu)障(zhang)(zhang)(zhang)等(deng)(deng)，可(ke)(ke)以逐一排查(cha)，找出問題(ti)進(jin)行(xing)相應(ying)的處理。 如果(guo)電(dian)(dian)(dian)(dian)視(shi)(shi)機(ji)(ji)(ji)電(dian)(dian)(dian)(dian)源指(zhi)示(shi)燈亮，則(ze)可(ke)(ke)能(neng)(neng)是用戶誤按遙控器的待(dai)機(ji)(ji)(ji)鍵使(shi)電(dian)(dian)(dian)(dian)視(shi)(shi)機(ji)(ji)(ji)進(jin)入(ru)待(dai)機(ji)(ji)(ji)狀(zhuang)態(tai)，所以顯(xian)示(shi)黑屏，只要(yao)重新按下待(dai)機(ji)(ji)(ji)鍵即可(ke)(ke)。 如果(guo)以上(shang)方法排查(cha)后，電(dian)(dian)(dian)(dian)視(shi)(shi)機(ji)(ji)(ji)仍(reng)然黑屏，有可(ke)(ke)能(neng)(neng)是硬件(jian)故(gu)(gu)障(zhang)(zhang)(zhang)引起(qi)的。比如電(dian)(dian)(dian)(dian)源模塊故(gu)(gu)障(zhang)(zhang)(zhang)、開(kai)關電(dian)(dian)(dian)(dian)路(lu)短路(lu)或開(kai)路(lu)、高壓板故(gu)(gu)障(zhang)(zhang)(zhang)、液晶屏或屏線故(gu)(gu)障(zhang)(zhang)(zhang)、主板芯片或者其他零(ling)部件(jian)故(gu)(gu)障(zhang)(zhang)(zhang)等(deng)(deng)，這時候需要(yao)聯系電(dian)(dian)(dian)(dian)視(shi)(shi)機(ji)(ji)(ji)的售后服(fu)務對(dui)電(dian)(dian)(dian)(dian)視(shi)(shi)機(ji)(ji)(ji)進(jin)行(xing)檢修才能(neng)(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。
