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

電視機尺寸多大合適

液晶電(dian)(dian)視(shi)機常見的(de)尺寸(cun)(cun)(cun)(cun)有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)。如果是(shi)臥室(shi)的(de)電(dian)(dian)視(shi)機，那么32寸(cun)(cun)(cun)(cun)、42寸(cun)(cun)(cun)(cun)是(shi)不錯的(de)選擇。如果是(shi)放置(zhi)在客廳(ting)，客廳(ting)又不是(shi)很大，42寸(cun)(cun)(cun)(cun)、46寸(cun)(cun)(cun)(cun)、47寸(cun)(cun)(cun)(cun)的(de)電(dian)(dian)視(shi)機就很適(shi)合。如果客廳(ting)面(mian)積很大，可以選50寸(cun)(cun)(cun)(cun)的(de)電(dian)(dian)視(shi)機。而(er)60寸(cun)(cun)(cun)(cun)適(shi)合別(bie)墅使用。

液晶電視尺寸計算方法

以(yi)32寸(cun)液晶電視(shi)機為例(li)，其尺寸(cun)計(ji)算(suan)方法：以(yi)1 英寸(cun)= 2.539999918 厘米(mi)，以(yi)電視(shi)平面對(dui)角線(xian)計(ji)算(suan)為準：32*2.539999918 =81.27997376厘米(mi)，按(an)常見4:3為比例(li)計(ji)算(suan)，一般(ban)是(shi)長=65.024cm，寬=48.768cm ；若按(an)16:9為比例(li)計(ji)算(suan)，一般(ban)是(shi)69=cm，寬=39cm。

電視機黑屏是怎么回事

如果電(dian)(dian)(dian)(dian)(dian)視(shi)(shi)機的電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)指示燈(deng)滅(mie)，則可(ke)能(neng)是電(dian)(dian)(dian)(dian)(dian)視(shi)(shi)機的電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)連接(jie)有問(wen)題(ti)，導(dao)致突然斷電(dian)(dian)(dian)(dian)(dian)黑(hei)屏。 比如電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)插頭松(song)動、電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)線(xian)故(gu)障等，可(ke)以逐一排查，找出問(wen)題(ti)進(jin)(jin)行(xing)相應(ying)的處理。 如果電(dian)(dian)(dian)(dian)(dian)視(shi)(shi)機電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)指示燈(deng)亮，則可(ke)能(neng)是用戶誤(wu)按遙(yao)控器(qi)的待(dai)機鍵使電(dian)(dian)(dian)(dian)(dian)視(shi)(shi)機進(jin)(jin)入待(dai)機狀態，所以顯示黑(hei)屏，只要重新按下待(dai)機鍵即可(ke)。 如果以上(shang)方(fang)法排查后(hou)，電(dian)(dian)(dian)(dian)(dian)視(shi)(shi)機仍(reng)然黑(hei)屏，有可(ke)能(neng)是硬件故(gu)障引起的。比如電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)模塊(kuai)故(gu)障、開關電(dian)(dian)(dian)(dian)(dian)路短路或開路、高壓(ya)板故(gu)障、液晶屏或屏線(xian)故(gu)障、主板芯片或者其他零部(bu)件故(gu)障等，這時候需要聯系電(dian)(dian)(dian)(dian)(dian)視(shi)(shi)機的售后(hou)服務(wu)對電(dian)(dian)(dian)(dian)(dian)視(shi)(shi)機進(jin)(jin)行(xing)檢修(xiu)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。
