電視機尺寸多大合適
液晶電視(shi)(shi)機(ji)(ji)常見的尺寸(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(ru)果(guo)是(shi)(shi)臥(wo)室的電視(shi)(shi)機(ji)(ji)，那(nei)么32寸(cun)(cun)(cun)(cun)、42寸(cun)(cun)(cun)(cun)是(shi)(shi)不(bu)錯的選擇。如(ru)果(guo)是(shi)(shi)放置在客廳(ting)，客廳(ting)又不(bu)是(shi)(shi)很大，42寸(cun)(cun)(cun)(cun)、46寸(cun)(cun)(cun)(cun)、47寸(cun)(cun)(cun)(cun)的電視(shi)(shi)機(ji)(ji)就很適(shi)合(he)。如(ru)果(guo)客廳(ting)面積很大，可以選50寸(cun)(cun)(cun)(cun)的電視(shi)(shi)機(ji)(ji)。而60寸(cun)(cun)(cun)(cun)適(shi)合(he)別墅(shu)使用。
液晶電視尺寸計算方法
以32寸(cun)液晶電視機為(wei)例，其尺寸(cun)計算方法(fa)：以1 英(ying)寸(cun)= 2.539999918 厘(li)米，以電視平(ping)面對角線計算為(wei)準：32*2.539999918 =81.27997376厘(li)米，按常見(jian)4:3為(wei)比例計算，一(yi)般(ban)是(shi)(shi)長=65.024cm，寬=48.768cm ；若按16:9為(wei)比例計算，一(yi)般(ban)是(shi)(shi)69=cm，寬=39cm。
電視機黑屏是怎么回事
如(ru)果(guo)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)視(shi)機(ji)的電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)指示燈(deng)(deng)滅，則可(ke)能(neng)是電(dian)(dian)(dian)(dian)(dian)(dian)(dian)視(shi)機(ji)的電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)連接有問題，導致突然(ran)斷電(dian)(dian)(dian)(dian)(dian)(dian)(dian)黑屏(ping)。 比如(ru)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)插頭松動、電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)線故(gu)(gu)障(zhang)等，可(ke)以(yi)逐(zhu)一(yi)排查(cha)，找出問題進行(xing)相(xiang)應(ying)的處理。 如(ru)果(guo)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)視(shi)機(ji)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)指示燈(deng)(deng)亮，則可(ke)能(neng)是用戶誤按遙控器的待(dai)(dai)機(ji)鍵(jian)使電(dian)(dian)(dian)(dian)(dian)(dian)(dian)視(shi)機(ji)進入待(dai)(dai)機(ji)狀(zhuang)態，所以(yi)顯示黑屏(ping)，只要(yao)重新按下待(dai)(dai)機(ji)鍵(jian)即可(ke)。 如(ru)果(guo)以(yi)上(shang)方法排查(cha)后，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)視(shi)機(ji)仍然(ran)黑屏(ping)，有可(ke)能(neng)是硬(ying)件(jian)故(gu)(gu)障(zhang)引起的。比如(ru)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)模塊故(gu)(gu)障(zhang)、開關電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路短路或開路、高壓板故(gu)(gu)障(zhang)、液(ye)晶屏(ping)或屏(ping)線故(gu)(gu)障(zhang)、主板芯片或者其他零(ling)部件(jian)故(gu)(gu)障(zhang)等，這時候需(xu)要(yao)聯(lian)系電(dian)(dian)(dian)(dian)(dian)(dian)(dian)視(shi)機(ji)的售后服務對電(dian)(dian)(dian)(dian)(dian)(dian)(dian)視(shi)機(ji)進行(xing)檢修才(cai)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。
