電視機尺寸與觀看距離

32寸建議觀看距離為2.3m；39寸建(jian)議(yi)觀看距離(li)為2.5m；42寸建議觀(guan)看距離為3.0m；46寸建議觀看距(ju)離(li)為3.5m；52寸建(jian)議觀看距離為4.0m；60寸建議觀看距(ju)離為4.5m。

電視機尺寸多大合適

液晶電視(shi)機(ji)常見的(de)尺寸(cun)(cun)(cun)有32寸(cun)(cun)(cun)、42寸(cun)(cun)(cun)、46寸(cun)(cun)(cun)、47寸(cun)(cun)(cun)、50寸(cun)(cun)(cun)、60寸(cun)(cun)(cun)。如果(guo)(guo)是臥室的(de)電視(shi)機(ji)，那么32寸(cun)(cun)(cun)、42寸(cun)(cun)(cun)是不(bu)錯的(de)選(xuan)擇。如果(guo)(guo)是放置在客廳，客廳又不(bu)是很大，42寸(cun)(cun)(cun)、46寸(cun)(cun)(cun)、47寸(cun)(cun)(cun)的(de)電視(shi)機(ji)就很適合。如果(guo)(guo)客廳面積很大，可(ke)以(yi)選(xuan)50寸(cun)(cun)(cun)的(de)電視(shi)機(ji)。而60寸(cun)(cun)(cun)適合別墅(shu)使用。

液晶電視尺寸計算方法

以(yi)32寸液(ye)晶電(dian)視機為(wei)例，其尺寸計算方法：以(yi)1 英寸= 2.539999918 厘(li)米，以(yi)電(dian)視平面(mian)對角線計算為(wei)準：32*2.539999918 =81.27997376厘(li)米，按常見4:3為(wei)比例計算，一般(ban)(ban)是(shi)長=65.024cm，寬=48.768cm ；若按16:9為(wei)比例計算，一般(ban)(ban)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(shi)機(ji)(ji)(ji)的電(dian)(dian)(dian)(dian)(dian)(dian)源指示燈(deng)滅(mie)，則可(ke)能(neng)(neng)是(shi)電(dian)(dian)(dian)(dian)(dian)(dian)視(shi)機(ji)(ji)(ji)的電(dian)(dian)(dian)(dian)(dian)(dian)源連接有問題(ti)，導致(zhi)突然(ran)斷電(dian)(dian)(dian)(dian)(dian)(dian)黑屏(ping)。 比如(ru)電(dian)(dian)(dian)(dian)(dian)(dian)源插頭松動、電(dian)(dian)(dian)(dian)(dian)(dian)源線故障(zhang)等，可(ke)以逐一(yi)排查(cha)，找出問題(ti)進行相應的處理。 如(ru)果電(dian)(dian)(dian)(dian)(dian)(dian)視(shi)機(ji)(ji)(ji)電(dian)(dian)(dian)(dian)(dian)(dian)源指示燈(deng)亮，則可(ke)能(neng)(neng)是(shi)用戶誤按遙(yao)控器的待機(ji)(ji)(ji)鍵使電(dian)(dian)(dian)(dian)(dian)(dian)視(shi)機(ji)(ji)(ji)進入待機(ji)(ji)(ji)狀態，所以顯示黑屏(ping)，只要(yao)(yao)重新按下(xia)待機(ji)(ji)(ji)鍵即(ji)可(ke)。 如(ru)果以上方法排查(cha)后，電(dian)(dian)(dian)(dian)(dian)(dian)視(shi)機(ji)(ji)(ji)仍然(ran)黑屏(ping)，有可(ke)能(neng)(neng)是(shi)硬件(jian)故障(zhang)引(yin)起的。比如(ru)電(dian)(dian)(dian)(dian)(dian)(dian)源模塊故障(zhang)、開關電(dian)(dian)(dian)(dian)(dian)(dian)路(lu)(lu)短(duan)路(lu)(lu)或開路(lu)(lu)、高(gao)壓板(ban)故障(zhang)、液晶屏(ping)或屏(ping)線故障(zhang)、主板(ban)芯(xin)片(pian)或者其他(ta)零部件(jian)故障(zhang)等，這時候需(xu)要(yao)(yao)聯系電(dian)(dian)(dian)(dian)(dian)(dian)視(shi)機(ji)(ji)(ji)的售后服務對電(dian)(dian)(dian)(dian)(dian)(dian)視(shi)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。
