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2.5m；42寸建議(yi)觀(guan)看距離為3.0m；46寸建議觀看距離為3.5m；52寸建議觀(guan)看距離為4.0m；60寸建(jian)議(yi)觀看距離為4.5m。

電視機尺寸多大合適

液(ye)晶電視(shi)機常(chang)見的(de)(de)尺寸(cun)(cun)(cun)(cun)(cun)有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)。如果是臥室的(de)(de)電視(shi)機，那么32寸(cun)(cun)(cun)(cun)(cun)、42寸(cun)(cun)(cun)(cun)(cun)是不錯的(de)(de)選(xuan)擇。如果是放置在客(ke)廳(ting)，客(ke)廳(ting)又不是很大(da)，42寸(cun)(cun)(cun)(cun)(cun)、46寸(cun)(cun)(cun)(cun)(cun)、47寸(cun)(cun)(cun)(cun)(cun)的(de)(de)電視(shi)機就很適合(he)。如果客(ke)廳(ting)面積很大(da)，可(ke)以選(xuan)50寸(cun)(cun)(cun)(cun)(cun)的(de)(de)電視(shi)機。而60寸(cun)(cun)(cun)(cun)(cun)適合(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(wei)例，其尺寸(cun)計(ji)(ji)(ji)算方法(fa)：以1 英(ying)寸(cun)= 2.539999918 厘米，以電(dian)視平面對(dui)角線計(ji)(ji)(ji)算為(wei)準(zhun)：32*2.539999918 =81.27997376厘米，按(an)常(chang)見(jian)4:3為(wei)比例計(ji)(ji)(ji)算，一(yi)般是(shi)(shi)長=65.024cm，寬=48.768cm ；若按(an)16:9為(wei)比例計(ji)(ji)(ji)算，一(yi)般是(shi)(shi)69=cm，寬=39cm。

電視機黑屏是怎么回事

如果電(dian)(dian)(dian)(dian)視(shi)機(ji)(ji)(ji)的電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)指(zhi)示(shi)燈(deng)滅，則可(ke)能(neng)是電(dian)(dian)(dian)(dian)視(shi)機(ji)(ji)(ji)的電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)連接有問(wen)題(ti)，導致突然斷電(dian)(dian)(dian)(dian)黑(hei)屏。 比如電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)插頭松動(dong)、電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)線故(gu)(gu)(gu)障等，可(ke)以逐一排查，找出問(wen)題(ti)進(jin)行相應(ying)的處理。 如果電(dian)(dian)(dian)(dian)視(shi)機(ji)(ji)(ji)電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)指(zhi)示(shi)燈(deng)亮，則可(ke)能(neng)是用戶誤按遙(yao)控(kong)器(qi)的待(dai)(dai)機(ji)(ji)(ji)鍵(jian)使(shi)電(dian)(dian)(dian)(dian)視(shi)機(ji)(ji)(ji)進(jin)入待(dai)(dai)機(ji)(ji)(ji)狀態，所以顯(xian)示(shi)黑(hei)屏，只要重新按下待(dai)(dai)機(ji)(ji)(ji)鍵(jian)即(ji)可(ke)。 如果以上(shang)方法排查后，電(dian)(dian)(dian)(dian)視(shi)機(ji)(ji)(ji)仍然黑(hei)屏，有可(ke)能(neng)是硬件(jian)故(gu)(gu)(gu)障引起的。比如電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)模塊故(gu)(gu)(gu)障、開關電(dian)(dian)(dian)(dian)路(lu)短路(lu)或開路(lu)、高壓板(ban)故(gu)(gu)(gu)障、液晶屏或屏線故(gu)(gu)(gu)障、主(zhu)板(ban)芯片(pian)或者其(qi)他(ta)零(ling)部件(jian)故(gu)(gu)(gu)障等，這時候需要聯系電(dian)(dian)(dian)(dian)視(shi)機(ji)(ji)(ji)的售后服(fu)務對電(dian)(dian)(dian)(dian)視(shi)機(ji)(ji)(ji)進(jin)行檢(jian)修才能(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。
