電視機尺寸多大合適
液晶電(dian)視機常見的(de)尺寸(cun)(cun)(cun)(cun)(cun)有(you)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(guo)是(shi)臥室(shi)的(de)電(dian)視機，那(nei)么(me)32寸(cun)(cun)(cun)(cun)(cun)、42寸(cun)(cun)(cun)(cun)(cun)是(shi)不錯的(de)選(xuan)擇。如(ru)果(guo)是(shi)放(fang)置在(zai)客(ke)廳(ting)，客(ke)廳(ting)又(you)不是(shi)很(hen)大(da)，42寸(cun)(cun)(cun)(cun)(cun)、46寸(cun)(cun)(cun)(cun)(cun)、47寸(cun)(cun)(cun)(cun)(cun)的(de)電(dian)視機就很(hen)適合(he)。如(ru)果(guo)客(ke)廳(ting)面積很(hen)大(da)，可以選(xuan)50寸(cun)(cun)(cun)(cun)(cun)的(de)電(dian)視機。而60寸(cun)(cun)(cun)(cun)(cun)適合(he)別(bie)墅使用。
液晶電視尺寸計算方法
以32寸(cun)液晶電視機為例，其尺(chi)寸(cun)計(ji)算(suan)方法：以1 英寸(cun)= 2.539999918 厘米，以電視平面對角線計(ji)算(suan)為準：32*2.539999918 =81.27997376厘米，按(an)(an)常見4:3為比例計(ji)算(suan)，一般(ban)是長=65.024cm，寬=48.768cm ；若按(an)(an)16:9為比例計(ji)算(suan)，一般(ban)是69=cm，寬=39cm。
電視機黑屏是怎么回事
如果電(dian)(dian)(dian)(dian)(dian)(dian)(dian)視(shi)(shi)(shi)機(ji)的電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)指(zhi)示(shi)(shi)燈滅，則可能是(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)視(shi)(shi)(shi)機(ji)的電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)連接(jie)有問題，導(dao)致突然(ran)斷電(dian)(dian)(dian)(dian)(dian)(dian)(dian)黑屏(ping)。 比如電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)插頭(tou)松動、電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)線故(gu)(gu)(gu)(gu)(gu)障(zhang)等(deng)，可以逐一排查，找出問題進(jin)行相應的處理。 如果電(dian)(dian)(dian)(dian)(dian)(dian)(dian)視(shi)(shi)(shi)機(ji)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)指(zhi)示(shi)(shi)燈亮，則可能是(shi)用戶誤按遙控器的待機(ji)鍵(jian)(jian)使(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)視(shi)(shi)(shi)機(ji)進(jin)入待機(ji)狀態，所以顯示(shi)(shi)黑屏(ping)，只要重新按下待機(ji)鍵(jian)(jian)即可。 如果以上方法排查后(hou)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)視(shi)(shi)(shi)機(ji)仍然(ran)黑屏(ping)，有可能是(shi)硬(ying)件(jian)故(gu)(gu)(gu)(gu)(gu)障(zhang)引(yin)起的。比如電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)模塊故(gu)(gu)(gu)(gu)(gu)障(zhang)、開(kai)關電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路短路或開(kai)路、高壓(ya)板故(gu)(gu)(gu)(gu)(gu)障(zhang)、液晶屏(ping)或屏(ping)線故(gu)(gu)(gu)(gu)(gu)障(zhang)、主板芯(xin)片或者其他零部(bu)件(jian)故(gu)(gu)(gu)(gu)(gu)障(zhang)等(deng)，這時(shi)候需(xu)要聯系電(dian)(dian)(dian)(dian)(dian)(dian)(dian)視(shi)(shi)(shi)機(ji)的售后(hou)服務對電(dian)(dian)(dian)(dian)(dian)(dian)(dian)視(shi)(shi)(shi)機(ji)進(jin)行檢修才能解(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。
