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寸建議觀看距離為3.0m；46寸建(jian)議觀(guan)看距離為3.5m；52寸建議觀看距離為4.0m；60寸(cun)建議觀看(kan)距離為(wei)4.5m。

電視機尺寸多大合適

液晶(jing)電(dian)視機常(chang)見(jian)的尺(chi)寸(cun)(cun)(cun)(cun)(cun)(cun)有32寸(cun)(cun)(cun)(cun)(cun)(cun)、42寸(cun)(cun)(cun)(cun)(cun)(cun)、46寸(cun)(cun)(cun)(cun)(cun)(cun)、47寸(cun)(cun)(cun)(cun)(cun)(cun)、50寸(cun)(cun)(cun)(cun)(cun)(cun)、60寸(cun)(cun)(cun)(cun)(cun)(cun)。如果(guo)(guo)是(shi)臥室的電(dian)視機，那么32寸(cun)(cun)(cun)(cun)(cun)(cun)、42寸(cun)(cun)(cun)(cun)(cun)(cun)是(shi)不(bu)錯的選(xuan)擇。如果(guo)(guo)是(shi)放置在(zai)客(ke)廳(ting)，客(ke)廳(ting)又不(bu)是(shi)很大，42寸(cun)(cun)(cun)(cun)(cun)(cun)、46寸(cun)(cun)(cun)(cun)(cun)(cun)、47寸(cun)(cun)(cun)(cun)(cun)(cun)的電(dian)視機就很適(shi)合(he)。如果(guo)(guo)客(ke)廳(ting)面積(ji)很大，可以選(xuan)50寸(cun)(cun)(cun)(cun)(cun)(cun)的電(dian)視機。而60寸(cun)(cun)(cun)(cun)(cun)(cun)適(shi)合(he)別(bie)墅使用。

液晶電視尺寸計算方法

以32寸(cun)液晶電視(shi)機(ji)為例(li)，其尺寸(cun)計(ji)算(suan)方法：以1 英寸(cun)= 2.539999918 厘(li)米，以電視(shi)平面對角線計(ji)算(suan)為準：32*2.539999918 =81.27997376厘(li)米，按常見4:3為比例(li)計(ji)算(suan)，一般是長=65.024cm，寬=48.768cm ；若(ruo)按16:9為比例(li)計(ji)算(suan)，一般是69=cm，寬=39cm。

電視機黑屏是怎么回事

如(ru)(ru)果電(dian)(dian)(dian)(dian)(dian)視(shi)機(ji)(ji)(ji)的電(dian)(dian)(dian)(dian)(dian)源(yuan)指示燈(deng)滅，則可能(neng)(neng)是(shi)(shi)電(dian)(dian)(dian)(dian)(dian)視(shi)機(ji)(ji)(ji)的電(dian)(dian)(dian)(dian)(dian)源(yuan)連接(jie)有(you)問(wen)題(ti)，導(dao)致突然斷電(dian)(dian)(dian)(dian)(dian)黑(hei)屏(ping)。 比(bi)如(ru)(ru)電(dian)(dian)(dian)(dian)(dian)源(yuan)插頭松動、電(dian)(dian)(dian)(dian)(dian)源(yuan)線故(gu)(gu)障(zhang)(zhang)等(deng)，可以逐一(yi)排(pai)(pai)查(cha)，找出問(wen)題(ti)進(jin)行相(xiang)應的處理。 如(ru)(ru)果電(dian)(dian)(dian)(dian)(dian)視(shi)機(ji)(ji)(ji)電(dian)(dian)(dian)(dian)(dian)源(yuan)指示燈(deng)亮，則可能(neng)(neng)是(shi)(shi)用戶誤按(an)遙控器(qi)的待(dai)機(ji)(ji)(ji)鍵(jian)使電(dian)(dian)(dian)(dian)(dian)視(shi)機(ji)(ji)(ji)進(jin)入(ru)待(dai)機(ji)(ji)(ji)狀態，所(suo)以顯示黑(hei)屏(ping)，只要重新按(an)下(xia)待(dai)機(ji)(ji)(ji)鍵(jian)即可。 如(ru)(ru)果以上方法(fa)排(pai)(pai)查(cha)后，電(dian)(dian)(dian)(dian)(dian)視(shi)機(ji)(ji)(ji)仍然黑(hei)屏(ping)，有(you)可能(neng)(neng)是(shi)(shi)硬件故(gu)(gu)障(zhang)(zhang)引起的。比(bi)如(ru)(ru)電(dian)(dian)(dian)(dian)(dian)源(yuan)模塊故(gu)(gu)障(zhang)(zhang)、開(kai)(kai)關電(dian)(dian)(dian)(dian)(dian)路短路或開(kai)(kai)路、高壓板(ban)故(gu)(gu)障(zhang)(zhang)、液晶(jing)屏(ping)或屏(ping)線故(gu)(gu)障(zhang)(zhang)、主(zhu)板(ban)芯片(pian)或者其他零部件故(gu)(gu)障(zhang)(zhang)等(deng)，這時(shi)候(hou)需要聯系電(dian)(dian)(dian)(dian)(dian)視(shi)機(ji)(ji)(ji)的售后服(fu)務對電(dian)(dian)(dian)(dian)(dian)視(shi)機(ji)(ji)(ji)進(jin)行檢修才能(neng)(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。
