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寸建(jian)議觀看距(ju)離為(wei)3.0m；46寸(cun)建(jian)議觀看距離為3.5m；52寸建議觀看距離為4.0m；60寸建議觀(guan)看距離為4.5m。

電視機尺寸多大合適

液(ye)晶電視機(ji)(ji)(ji)常見的尺寸(cun)(cun)有(you)32寸(cun)(cun)、42寸(cun)(cun)、46寸(cun)(cun)、47寸(cun)(cun)、50寸(cun)(cun)、60寸(cun)(cun)。如果是(shi)臥(wo)室(shi)的電視機(ji)(ji)(ji)，那么32寸(cun)(cun)、42寸(cun)(cun)是(shi)不(bu)錯的選擇。如果是(shi)放置在客廳(ting)(ting)，客廳(ting)(ting)又不(bu)是(shi)很大，42寸(cun)(cun)、46寸(cun)(cun)、47寸(cun)(cun)的電視機(ji)(ji)(ji)就很適合(he)(he)。如果客廳(ting)(ting)面積很大，可以選50寸(cun)(cun)的電視機(ji)(ji)(ji)。而(er)60寸(cun)(cun)適合(he)(he)別墅使用。

液晶電視尺寸計算方法

以(yi)32寸(cun)液晶(jing)電視機(ji)為(wei)例，其(qi)尺寸(cun)計算方(fang)法(fa)：以(yi)1 英寸(cun)= 2.539999918 厘米，以(yi)電視平(ping)面對(dui)角線計算為(wei)準：32*2.539999918 =81.27997376厘米，按(an)常(chang)見4:3為(wei)比(bi)例計算，一般是(shi)長=65.024cm，寬=48.768cm ；若按(an)16:9為(wei)比(bi)例計算，一般是(shi)69=cm，寬=39cm。

電視機黑屏是怎么回事

如(ru)果電(dian)(dian)(dian)(dian)(dian)(dian)視機(ji)(ji)(ji)的電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)指(zhi)示(shi)燈滅(mie)，則可能(neng)(neng)是電(dian)(dian)(dian)(dian)(dian)(dian)視機(ji)(ji)(ji)的電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)連接有問題，導致突然(ran)斷電(dian)(dian)(dian)(dian)(dian)(dian)黑屏。 比如(ru)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)插頭松(song)動、電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)線故(gu)障(zhang)等，可以(yi)逐一排查(cha)，找出(chu)問題進行相應的處理。 如(ru)果電(dian)(dian)(dian)(dian)(dian)(dian)視機(ji)(ji)(ji)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)指(zhi)示(shi)燈亮，則可能(neng)(neng)是用(yong)戶(hu)誤按遙控器(qi)的待機(ji)(ji)(ji)鍵(jian)使電(dian)(dian)(dian)(dian)(dian)(dian)視機(ji)(ji)(ji)進入(ru)待機(ji)(ji)(ji)狀(zhuang)態，所以(yi)顯(xian)示(shi)黑屏，只(zhi)要(yao)(yao)重新按下待機(ji)(ji)(ji)鍵(jian)即可。 如(ru)果以(yi)上(shang)方法排查(cha)后，電(dian)(dian)(dian)(dian)(dian)(dian)視機(ji)(ji)(ji)仍然(ran)黑屏，有可能(neng)(neng)是硬件(jian)故(gu)障(zhang)引起的。比如(ru)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)模塊(kuai)故(gu)障(zhang)、開關電(dian)(dian)(dian)(dian)(dian)(dian)路(lu)短路(lu)或(huo)(huo)開路(lu)、高壓板故(gu)障(zhang)、液晶屏或(huo)(huo)屏線故(gu)障(zhang)、主板芯(xin)片或(huo)(huo)者其他零部(bu)件(jian)故(gu)障(zhang)等，這時候需要(yao)(yao)聯系電(dian)(dian)(dian)(dian)(dian)(dian)視機(ji)(ji)(ji)的售(shou)后服務對電(dian)(dian)(dian)(dian)(dian)(dian)視機(ji)(ji)(ji)進行檢修(xiu)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。
