電視機尺寸多大合適

液晶電視(shi)機(ji)常(chang)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)。如果(guo)是(shi)臥室的電視(shi)機(ji)，那么32寸(cun)(cun)(cun)(cun)、42寸(cun)(cun)(cun)(cun)是(shi)不錯的選擇。如果(guo)是(shi)放置(zhi)在客廳(ting)，客廳(ting)又不是(shi)很(hen)大(da)，42寸(cun)(cun)(cun)(cun)、46寸(cun)(cun)(cun)(cun)、47寸(cun)(cun)(cun)(cun)的電視(shi)機(ji)就(jiu)很(hen)適合(he)。如果(guo)客廳(ting)面積(ji)很(hen)大(da)，可以(yi)選50寸(cun)(cun)(cun)(cun)的電視(shi)機(ji)。而60寸(cun)(cun)(cun)(cun)適合(he)別墅使用。

液晶電視尺寸計算方法

以(yi)32寸(cun)液晶電視機為(wei)例，其(qi)尺寸(cun)計(ji)算(suan)方法(fa)：以(yi)1 英寸(cun)= 2.539999918 厘米(mi)，以(yi)電視平(ping)面對角線(xian)計(ji)算(suan)為(wei)準(zhun)：32*2.539999918 =81.27997376厘米(mi)，按常見4:3為(wei)比例計(ji)算(suan)，一(yi)般是長(chang)=65.024cm，寬=48.768cm ；若(ruo)按16:9為(wei)比例計(ji)算(suan)，一(yi)般是69=cm，寬=39cm。

電視機黑屏是怎么回事

如(ru)果(guo)(guo)電(dian)(dian)(dian)(dian)(dian)(dian)視(shi)機(ji)(ji)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)指示(shi)(shi)燈(deng)滅，則(ze)可(ke)(ke)(ke)能是電(dian)(dian)(dian)(dian)(dian)(dian)視(shi)機(ji)(ji)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)連接有(you)問(wen)題，導致(zhi)突然(ran)斷電(dian)(dian)(dian)(dian)(dian)(dian)黑(hei)屏(ping)(ping)。 比(bi)(bi)如(ru)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)插頭松動、電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)線故障(zhang)等，可(ke)(ke)(ke)以(yi)逐一排查(cha)，找出問(wen)題進(jin)行相應的(de)(de)處理。 如(ru)果(guo)(guo)電(dian)(dian)(dian)(dian)(dian)(dian)視(shi)機(ji)(ji)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)指示(shi)(shi)燈(deng)亮(liang)，則(ze)可(ke)(ke)(ke)能是用戶誤(wu)按遙(yao)控(kong)器的(de)(de)待(dai)(dai)(dai)機(ji)(ji)鍵使電(dian)(dian)(dian)(dian)(dian)(dian)視(shi)機(ji)(ji)進(jin)入待(dai)(dai)(dai)機(ji)(ji)狀態，所以(yi)顯(xian)示(shi)(shi)黑(hei)屏(ping)(ping)，只要(yao)重新按下待(dai)(dai)(dai)機(ji)(ji)鍵即可(ke)(ke)(ke)。 如(ru)果(guo)(guo)以(yi)上方法(fa)排查(cha)后，電(dian)(dian)(dian)(dian)(dian)(dian)視(shi)機(ji)(ji)仍然(ran)黑(hei)屏(ping)(ping)，有(you)可(ke)(ke)(ke)能是硬件故障(zhang)引起的(de)(de)。比(bi)(bi)如(ru)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)模塊故障(zhang)、開關電(dian)(dian)(dian)(dian)(dian)(dian)路短(duan)路或開路、高壓板(ban)故障(zhang)、液晶屏(ping)(ping)或屏(ping)(ping)線故障(zhang)、主(zhu)板(ban)芯(xin)片或者(zhe)其他零部件故障(zhang)等，這(zhe)時候(hou)需要(yao)聯系電(dian)(dian)(dian)(dian)(dian)(dian)視(shi)機(ji)(ji)的(de)(de)售后服務對(dui)電(dian)(dian)(dian)(dian)(dian)(dian)視(shi)機(ji)(ji)進(jin)行檢修才能解決。

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。
