電視機尺寸與觀看距離

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

電視機尺寸多大合適

液晶電(dian)視(shi)(shi)(shi)機常見的(de)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)。如果(guo)(guo)(guo)是(shi)臥室(shi)的(de)電(dian)視(shi)(shi)(shi)機，那(nei)么32寸(cun)(cun)、42寸(cun)(cun)是(shi)不(bu)錯(cuo)的(de)選擇。如果(guo)(guo)(guo)是(shi)放置在客(ke)廳，客(ke)廳又不(bu)是(shi)很大，42寸(cun)(cun)、46寸(cun)(cun)、47寸(cun)(cun)的(de)電(dian)視(shi)(shi)(shi)機就很適合。如果(guo)(guo)(guo)客(ke)廳面積很大，可(ke)以選50寸(cun)(cun)的(de)電(dian)視(shi)(shi)(shi)機。而60寸(cun)(cun)適合別墅使用。

液晶電視尺寸計算方法

以(yi)32寸液(ye)晶電(dian)視(shi)機為例，其尺寸計(ji)(ji)算(suan)方法：以(yi)1 英寸= 2.539999918 厘(li)米(mi)，以(yi)電(dian)視(shi)平面對角線計(ji)(ji)算(suan)為準：32*2.539999918 =81.27997376厘(li)米(mi)，按常見4:3為比(bi)例計(ji)(ji)算(suan)，一般是(shi)(shi)長=65.024cm，寬(kuan)(kuan)=48.768cm ；若按16:9為比(bi)例計(ji)(ji)算(suan)，一般是(shi)(shi)69=cm，寬(kuan)(kuan)=39cm。

電視機黑屏是怎么回事

如果(guo)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)視(shi)(shi)機(ji)的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)指示燈滅，則可(ke)能(neng)是(shi)(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)視(shi)(shi)機(ji)的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)連接(jie)有(you)問(wen)題，導致(zhi)突然斷(duan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)黑屏。 比如電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)插(cha)頭(tou)松動(dong)、電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)線故障(zhang)(zhang)等，可(ke)以(yi)逐一排查(cha)(cha)，找出問(wen)題進(jin)(jin)行(xing)(xing)相應的(de)處理。 如果(guo)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)視(shi)(shi)機(ji)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)指示燈亮(liang)，則可(ke)能(neng)是(shi)(shi)用戶誤按遙控器的(de)待(dai)(dai)機(ji)鍵使電(dian)(dian)(dian)(dian)(dian)(dian)(dian)視(shi)(shi)機(ji)進(jin)(jin)入待(dai)(dai)機(ji)狀(zhuang)態(tai)，所(suo)以(yi)顯示黑屏，只要重新(xin)按下待(dai)(dai)機(ji)鍵即可(ke)。 如果(guo)以(yi)上(shang)方(fang)法(fa)排查(cha)(cha)后，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)視(shi)(shi)機(ji)仍然黑屏，有(you)可(ke)能(neng)是(shi)(shi)硬件(jian)故障(zhang)(zhang)引起的(de)。比如電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)模(mo)塊故障(zhang)(zhang)、開關電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)短(duan)路(lu)或開路(lu)、高壓板(ban)故障(zhang)(zhang)、液(ye)晶(jing)屏或屏線故障(zhang)(zhang)、主板(ban)芯片(pian)或者其他零部件(jian)故障(zhang)(zhang)等，這時候需(xu)要聯系電(dian)(dian)(dian)(dian)(dian)(dian)(dian)視(shi)(shi)機(ji)的(de)售后服務對電(dian)(dian)(dian)(dian)(dian)(dian)(dian)視(shi)(shi)機(ji)進(jin)(jin)行(xing)(xing)檢(jian)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。
