電視機尺寸多大合適
液(ye)晶(jing)電(dian)視機(ji)常見(jian)的尺寸(cun)(cun)(cun)(cun)(cun)有32寸(cun)(cun)(cun)(cun)(cun)、42寸(cun)(cun)(cun)(cun)(cun)、46寸(cun)(cun)(cun)(cun)(cun)、47寸(cun)(cun)(cun)(cun)(cun)、50寸(cun)(cun)(cun)(cun)(cun)、60寸(cun)(cun)(cun)(cun)(cun)。如(ru)果是(shi)臥(wo)室的電(dian)視機(ji),那么32寸(cun)(cun)(cun)(cun)(cun)、42寸(cun)(cun)(cun)(cun)(cun)是(shi)不錯的選(xuan)擇。如(ru)果是(shi)放置(zhi)在客(ke)廳(ting),客(ke)廳(ting)又不是(shi)很(hen)大,42寸(cun)(cun)(cun)(cun)(cun)、46寸(cun)(cun)(cun)(cun)(cun)、47寸(cun)(cun)(cun)(cun)(cun)的電(dian)視機(ji)就(jiu)很(hen)適合。如(ru)果客(ke)廳(ting)面積很(hen)大,可以(yi)選(xuan)50寸(cun)(cun)(cun)(cun)(cun)的電(dian)視機(ji)。而60寸(cun)(cun)(cun)(cun)(cun)適合別(bie)墅(shu)使用。
液晶電視尺寸計算方法
以32寸(cun)液晶電(dian)(dian)視機(ji)為例,其尺寸(cun)計算方法:以1 英寸(cun)= 2.539999918 厘米(mi),以電(dian)(dian)視平面對角線計算為準:32*2.539999918 =81.27997376厘米(mi),按常(chang)見4:3為比例計算,一般是長=65.024cm,寬(kuan)=48.768cm ;若(ruo)按16:9為比例計算,一般是69=cm,寬(kuan)=39cm。
電視機黑屏是怎么回事
如(ru)(ru)果(guo)電(dian)(dian)(dian)視機(ji)(ji)的電(dian)(dian)(dian)源(yuan)指示燈(deng)滅,則(ze)可(ke)能是電(dian)(dian)(dian)視機(ji)(ji)的電(dian)(dian)(dian)源(yuan)連接有(you)(you)問(wen)題(ti),導致突(tu)然斷(duan)電(dian)(dian)(dian)黑(hei)屏(ping)。 比如(ru)(ru)電(dian)(dian)(dian)源(yuan)插(cha)頭松動、電(dian)(dian)(dian)源(yuan)線故障(zhang)等,可(ke)以(yi)逐一排查(cha)(cha),找出問(wen)題(ti)進行(xing)相應的處理。 如(ru)(ru)果(guo)電(dian)(dian)(dian)視機(ji)(ji)電(dian)(dian)(dian)源(yuan)指示燈(deng)亮,則(ze)可(ke)能是用戶誤按遙控器的待(dai)機(ji)(ji)鍵使電(dian)(dian)(dian)視機(ji)(ji)進入待(dai)機(ji)(ji)狀(zhuang)態,所以(yi)顯(xian)示黑(hei)屏(ping),只要(yao)(yao)重新(xin)按下待(dai)機(ji)(ji)鍵即可(ke)。 如(ru)(ru)果(guo)以(yi)上方(fang)法排查(cha)(cha)后(hou)(hou),電(dian)(dian)(dian)視機(ji)(ji)仍然黑(hei)屏(ping),有(you)(you)可(ke)能是硬件故障(zhang)引(yin)起的。比如(ru)(ru)電(dian)(dian)(dian)源(yuan)模塊故障(zhang)、開關電(dian)(dian)(dian)路(lu)短路(lu)或開路(lu)、高壓板故障(zhang)、液晶屏(ping)或屏(ping)線故障(zhang)、主板芯片或者其(qi)他(ta)零部(bu)件故障(zhang)等,這時候需要(yao)(yao)聯系電(dian)(dian)(dian)視機(ji)(ji)的售(shou)后(hou)(hou)服(fu)務對(dui)電(dian)(dian)(dian)視機(ji)(ji)進行(xing)檢修才(cai)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。
