電視機尺寸與觀看距離

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

電視機尺寸多大合適

液晶電視(shi)機常見的尺寸(cun)(cun)有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(ru)果是(shi)(shi)臥室的電視(shi)機，那么32寸(cun)(cun)、42寸(cun)(cun)是(shi)(shi)不錯的選擇(ze)。如(ru)果是(shi)(shi)放(fang)置在客(ke)廳，客(ke)廳又不是(shi)(shi)很(hen)(hen)大，42寸(cun)(cun)、46寸(cun)(cun)、47寸(cun)(cun)的電視(shi)機就很(hen)(hen)適(shi)合(he)。如(ru)果客(ke)廳面積很(hen)(hen)大，可(ke)以(yi)選50寸(cun)(cun)的電視(shi)機。而(er)60寸(cun)(cun)適(shi)合(he)別墅使用。

液晶電視尺寸計算方法

以32寸(cun)液晶電(dian)視機為例，其尺寸(cun)計(ji)算(suan)方法(fa)：以1 英寸(cun)= 2.539999918 厘(li)米，以電(dian)視平面對角線計(ji)算(suan)為準：32*2.539999918 =81.27997376厘(li)米，按(an)(an)常見4:3為比例計(ji)算(suan)，一般是長=65.024cm，寬=48.768cm ；若按(an)(an)16:9為比例計(ji)算(suan)，一般是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(shi)(shi)機的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)指示燈(deng)滅，則可(ke)能(neng)是電(dian)(dian)(dian)(dian)(dian)(dian)視(shi)(shi)機的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)連接有(you)問(wen)題，導致突然(ran)斷電(dian)(dian)(dian)(dian)(dian)(dian)黑屏(ping)(ping)(ping)。 比(bi)如(ru)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)插頭松動、電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)線故(gu)障(zhang)等(deng)，可(ke)以逐一排查，找(zhao)出問(wen)題進(jin)行(xing)相(xiang)應的(de)(de)(de)(de)處理。 如(ru)果電(dian)(dian)(dian)(dian)(dian)(dian)視(shi)(shi)機電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)指示燈(deng)亮，則可(ke)能(neng)是用戶誤(wu)按遙控(kong)器的(de)(de)(de)(de)待(dai)(dai)機鍵使(shi)電(dian)(dian)(dian)(dian)(dian)(dian)視(shi)(shi)機進(jin)入待(dai)(dai)機狀態，所以顯示黑屏(ping)(ping)(ping)，只要重新(xin)按下(xia)待(dai)(dai)機鍵即可(ke)。 如(ru)果以上方法(fa)排查后，電(dian)(dian)(dian)(dian)(dian)(dian)視(shi)(shi)機仍然(ran)黑屏(ping)(ping)(ping)，有(you)可(ke)能(neng)是硬件故(gu)障(zhang)引起的(de)(de)(de)(de)。比(bi)如(ru)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)模(mo)塊(kuai)故(gu)障(zhang)、開關電(dian)(dian)(dian)(dian)(dian)(dian)路(lu)短路(lu)或(huo)開路(lu)、高壓板故(gu)障(zhang)、液晶屏(ping)(ping)(ping)或(huo)屏(ping)(ping)(ping)線故(gu)障(zhang)、主(zhu)板芯片(pian)或(huo)者其他(ta)零部(bu)件故(gu)障(zhang)等(deng)，這時候需要聯(lian)系電(dian)(dian)(dian)(dian)(dian)(dian)視(shi)(shi)機的(de)(de)(de)(de)售(shou)后服(fu)務對電(dian)(dian)(dian)(dian)(dian)(dian)視(shi)(shi)機進(jin)行(xing)檢修才能(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。
