電視機尺寸與觀看距離
32寸建議觀看距離為2.3m;39寸建議觀看距離(li)為(wei)2.5m;42寸(cun)建(jian)議觀看距(ju)離為3.0m;46寸(cun)建議觀看(kan)距離為(wei)3.5m;52寸建議(yi)觀(guan)看距離(li)為4.0m;60寸建議觀(guan)看距離為4.5m。
電視機尺寸多大合適
液晶電視機(ji)常見的尺(chi)寸(cun)(cun)(cun)(cun)有(you)32寸(cun)(cun)(cun)(cun)、42寸(cun)(cun)(cun)(cun)、46寸(cun)(cun)(cun)(cun)、47寸(cun)(cun)(cun)(cun)、50寸(cun)(cun)(cun)(cun)、60寸(cun)(cun)(cun)(cun)。如果(guo)是(shi)(shi)臥室的電視機(ji),那么(me)32寸(cun)(cun)(cun)(cun)、42寸(cun)(cun)(cun)(cun)是(shi)(shi)不(bu)錯的選擇。如果(guo)是(shi)(shi)放置在客(ke)廳,客(ke)廳又不(bu)是(shi)(shi)很(hen)(hen)大(da),42寸(cun)(cun)(cun)(cun)、46寸(cun)(cun)(cun)(cun)、47寸(cun)(cun)(cun)(cun)的電視機(ji)就很(hen)(hen)適合(he)。如果(guo)客(ke)廳面(mian)積很(hen)(hen)大(da),可以選50寸(cun)(cun)(cun)(cun)的電視機(ji)。而60寸(cun)(cun)(cun)(cun)適合(he)別(bie)墅使用。
液晶電視尺寸計算方法
以32寸液晶電(dian)視(shi)機為(wei)例(li),其尺寸計算方法:以1 英寸= 2.539999918 厘(li)米(mi),以電(dian)視(shi)平面對角(jiao)線計算為(wei)準:32*2.539999918 =81.27997376厘(li)米(mi),按常見4:3為(wei)比(bi)例(li)計算,一般是(shi)長=65.024cm,寬=48.768cm ;若按16:9為(wei)比(bi)例(li)計算,一般是(shi)69=cm,寬=39cm。
電視機黑屏是怎么回事
如果(guo)(guo)電(dian)(dian)(dian)視(shi)(shi)機(ji)(ji)(ji)的(de)電(dian)(dian)(dian)源(yuan)(yuan)指(zhi)示燈滅(mie),則可能是電(dian)(dian)(dian)視(shi)(shi)機(ji)(ji)(ji)的(de)電(dian)(dian)(dian)源(yuan)(yuan)連接有問題,導致突然(ran)(ran)斷電(dian)(dian)(dian)黑屏(ping)。 比如電(dian)(dian)(dian)源(yuan)(yuan)插頭松(song)動、電(dian)(dian)(dian)源(yuan)(yuan)線(xian)故(gu)障(zhang)等(deng)(deng),可以(yi)逐一排(pai)查(cha),找出問題進行相應的(de)處理。 如果(guo)(guo)電(dian)(dian)(dian)視(shi)(shi)機(ji)(ji)(ji)電(dian)(dian)(dian)源(yuan)(yuan)指(zhi)示燈亮(liang),則可能是用戶誤按遙控器的(de)待(dai)機(ji)(ji)(ji)鍵使電(dian)(dian)(dian)視(shi)(shi)機(ji)(ji)(ji)進入待(dai)機(ji)(ji)(ji)狀態,所以(yi)顯(xian)示黑屏(ping),只要重新按下(xia)待(dai)機(ji)(ji)(ji)鍵即可。 如果(guo)(guo)以(yi)上方法排(pai)查(cha)后(hou),電(dian)(dian)(dian)視(shi)(shi)機(ji)(ji)(ji)仍(reng)然(ran)(ran)黑屏(ping),有可能是硬件(jian)故(gu)障(zhang)引起的(de)。比如電(dian)(dian)(dian)源(yuan)(yuan)模塊故(gu)障(zhang)、開(kai)關電(dian)(dian)(dian)路短(duan)路或(huo)開(kai)路、高壓板故(gu)障(zhang)、液晶屏(ping)或(huo)屏(ping)線(xian)故(gu)障(zhang)、主板芯(xin)片(pian)或(huo)者其他零部件(jian)故(gu)障(zhang)等(deng)(deng),這時候需要聯系電(dian)(dian)(dian)視(shi)(shi)機(ji)(ji)(ji)的(de)售后(hou)服務對(dui)電(dian)(dian)(dian)視(shi)(shi)機(ji)(ji)(ji)進行檢修才能解決。
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。
