電視機尺寸與觀看距離
32寸建議觀看距離為2.3m；39寸建(jian)議觀看距離為2.5m；42寸建議觀看距離(li)為3.0m；46寸建議(yi)觀看距離為3.5m；52寸建議觀看距(ju)離為4.0m；60寸建議觀看(kan)距離為4.5m。
電視機尺寸多大合適
液晶電(dian)視機(ji)常見的(de)(de)尺寸(cun)(cun)有(you)32寸(cun)(cun)、42寸(cun)(cun)、46寸(cun)(cun)、47寸(cun)(cun)、50寸(cun)(cun)、60寸(cun)(cun)。如(ru)果是臥室的(de)(de)電(dian)視機(ji)，那么32寸(cun)(cun)、42寸(cun)(cun)是不錯的(de)(de)選擇。如(ru)果是放(fang)置(zhi)在客廳(ting)，客廳(ting)又不是很(hen)大(da)，42寸(cun)(cun)、46寸(cun)(cun)、47寸(cun)(cun)的(de)(de)電(dian)視機(ji)就(jiu)很(hen)適合。如(ru)果客廳(ting)面積很(hen)大(da)，可(ke)以選50寸(cun)(cun)的(de)(de)電(dian)視機(ji)。而60寸(cun)(cun)適合別墅(shu)使(shi)用。
液晶電視尺寸計算方法
以(yi)32寸(cun)液晶電(dian)視機為(wei)例，其(qi)尺寸(cun)計算(suan)(suan)方(fang)法：以(yi)1 英寸(cun)= 2.539999918 厘(li)米(mi)，以(yi)電(dian)視平面對(dui)角線計算(suan)(suan)為(wei)準：32*2.539999918 =81.27997376厘(li)米(mi)，按常(chang)見4:3為(wei)比(bi)例計算(suan)(suan)，一(yi)般是長=65.024cm，寬=48.768cm ；若按16:9為(wei)比(bi)例計算(suan)(suan)，一(yi)般是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)視(shi)機(ji)(ji)(ji)的(de)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)指示(shi)(shi)燈滅，則(ze)可能是(shi)電(dian)(dian)(dian)(dian)(dian)(dian)視(shi)機(ji)(ji)(ji)的(de)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)連接有問題(ti)，導致突然斷電(dian)(dian)(dian)(dian)(dian)(dian)黑(hei)屏(ping)。 比(bi)如(ru)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)插頭(tou)松動、電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)線故(gu)(gu)(gu)障(zhang)(zhang)等，可以逐一排查，找(zhao)出(chu)問題(ti)進行相應的(de)處理。 如(ru)果(guo)電(dian)(dian)(dian)(dian)(dian)(dian)視(shi)機(ji)(ji)(ji)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)指示(shi)(shi)燈亮，則(ze)可能是(shi)用戶(hu)誤按(an)遙控器的(de)待機(ji)(ji)(ji)鍵使電(dian)(dian)(dian)(dian)(dian)(dian)視(shi)機(ji)(ji)(ji)進入待機(ji)(ji)(ji)狀態(tai)，所以顯示(shi)(shi)黑(hei)屏(ping)，只要重新按(an)下待機(ji)(ji)(ji)鍵即可。 如(ru)果(guo)以上(shang)方(fang)法排查后，電(dian)(dian)(dian)(dian)(dian)(dian)視(shi)機(ji)(ji)(ji)仍然黑(hei)屏(ping)，有可能是(shi)硬件故(gu)(gu)(gu)障(zhang)(zhang)引起的(de)。比(bi)如(ru)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)模塊(kuai)故(gu)(gu)(gu)障(zhang)(zhang)、開關電(dian)(dian)(dian)(dian)(dian)(dian)路(lu)短路(lu)或開路(lu)、高壓板故(gu)(gu)(gu)障(zhang)(zhang)、液晶屏(ping)或屏(ping)線故(gu)(gu)(gu)障(zhang)(zhang)、主板芯片或者(zhe)其(qi)他零(ling)部(bu)件故(gu)(gu)(gu)障(zhang)(zhang)等，這時候需要聯系電(dian)(dian)(dian)(dian)(dian)(dian)視(shi)機(ji)(ji)(ji)的(de)售后服務(wu)對電(dian)(dian)(dian)(dian)(dian)(dian)視(shi)機(ji)(ji)(ji)進行檢修才能解決。
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。
