電視行業簡介

電視機尺寸與觀看距離

32寸建議觀看距離為2.3m；39寸建議觀看距(ju)離為2.5m；42寸建議觀看距離(li)為3.0m；46寸建(jian)議觀看(kan)距(ju)離(li)為3.5m；52寸建議(yi)觀看(kan)距離(li)為4.0m；60寸建(jian)議(yi)觀看距離(li)為4.5m。

電視機尺寸多大合適

液晶電(dian)視機常見的(de)(de)尺(chi)寸(cun)(cun)有32寸(cun)(cun)、42寸(cun)(cun)、46寸(cun)(cun)、47寸(cun)(cun)、50寸(cun)(cun)、60寸(cun)(cun)。如果(guo)(guo)是(shi)臥室(shi)的(de)(de)電(dian)視機，那么32寸(cun)(cun)、42寸(cun)(cun)是(shi)不錯的(de)(de)選擇。如果(guo)(guo)是(shi)放置在(zai)客(ke)廳，客(ke)廳又不是(shi)很(hen)大(da)，42寸(cun)(cun)、46寸(cun)(cun)、47寸(cun)(cun)的(de)(de)電(dian)視機就(jiu)很(hen)適合。如果(guo)(guo)客(ke)廳面(mian)積很(hen)大(da)，可以(yi)選50寸(cun)(cun)的(de)(de)電(dian)視機。而60寸(cun)(cun)適合別墅(shu)使用。

液晶電視尺寸計算方法

以32寸(cun)液晶(jing)電(dian)(dian)視(shi)機為(wei)例，其尺寸(cun)計(ji)算(suan)(suan)方法(fa)：以1 英寸(cun)= 2.539999918 厘米，以電(dian)(dian)視(shi)平面對角線計(ji)算(suan)(suan)為(wei)準(zhun)：32*2.539999918 =81.27997376厘米，按(an)常見4:3為(wei)比(bi)例計(ji)算(suan)(suan)，一般(ban)是長=65.024cm，寬=48.768cm ；若(ruo)按(an)16:9為(wei)比(bi)例計(ji)算(suan)(suan)，一般(ban)是69=cm，寬=39cm。

電視機黑屏是怎么回事

如(ru)果電(dian)(dian)(dian)(dian)(dian)視機(ji)(ji)(ji)的電(dian)(dian)(dian)(dian)(dian)源(yuan)指示(shi)燈滅，則可(ke)能是電(dian)(dian)(dian)(dian)(dian)視機(ji)(ji)(ji)的電(dian)(dian)(dian)(dian)(dian)源(yuan)連接有問(wen)題，導(dao)致突然斷(duan)電(dian)(dian)(dian)(dian)(dian)黑(hei)(hei)屏(ping)(ping)(ping)。 比如(ru)電(dian)(dian)(dian)(dian)(dian)源(yuan)插頭(tou)松動、電(dian)(dian)(dian)(dian)(dian)源(yuan)線(xian)(xian)故(gu)障(zhang)(zhang)等，可(ke)以(yi)逐(zhu)一排(pai)查(cha)，找出(chu)問(wen)題進行相應的處(chu)理。 如(ru)果電(dian)(dian)(dian)(dian)(dian)視機(ji)(ji)(ji)電(dian)(dian)(dian)(dian)(dian)源(yuan)指示(shi)燈亮，則可(ke)能是用戶誤按遙控器的待機(ji)(ji)(ji)鍵(jian)使(shi)電(dian)(dian)(dian)(dian)(dian)視機(ji)(ji)(ji)進入待機(ji)(ji)(ji)狀態，所(suo)以(yi)顯示(shi)黑(hei)(hei)屏(ping)(ping)(ping)，只要重(zhong)新按下待機(ji)(ji)(ji)鍵(jian)即可(ke)。 如(ru)果以(yi)上方法排(pai)查(cha)后，電(dian)(dian)(dian)(dian)(dian)視機(ji)(ji)(ji)仍然黑(hei)(hei)屏(ping)(ping)(ping)，有可(ke)能是硬件(jian)故(gu)障(zhang)(zhang)引起的。比如(ru)電(dian)(dian)(dian)(dian)(dian)源(yuan)模塊故(gu)障(zhang)(zhang)、開(kai)關電(dian)(dian)(dian)(dian)(dian)路短路或開(kai)路、高壓板故(gu)障(zhang)(zhang)、液晶屏(ping)(ping)(ping)或屏(ping)(ping)(ping)線(xian)(xian)故(gu)障(zhang)(zhang)、主(zhu)板芯片或者其他零部件(jian)故(gu)障(zhang)(zhang)等，這時候需要聯系(xi)電(dian)(dian)(dian)(dian)(dian)視機(ji)(ji)(ji)的售后服務對(dui)電(dian)(dian)(dian)(dian)(dian)視機(ji)(ji)(ji)進行檢(jian)修才能解決(jue)。

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。
