電視機尺寸與觀看距離

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

電視機尺寸多大合適

液晶電(dian)視(shi)機(ji)常見的尺寸(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)(ru)果是(shi)(shi)臥室的電(dian)視(shi)機(ji)，那么(me)32寸(cun)(cun)(cun)(cun)(cun)、42寸(cun)(cun)(cun)(cun)(cun)是(shi)(shi)不(bu)錯的選擇。如(ru)(ru)果是(shi)(shi)放置在(zai)客廳(ting)，客廳(ting)又不(bu)是(shi)(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)的電(dian)視(shi)機(ji)就很(hen)適合(he)。如(ru)(ru)果客廳(ting)面(mian)積很(hen)大(da)，可以(yi)選50寸(cun)(cun)(cun)(cun)(cun)的電(dian)視(shi)機(ji)。而60寸(cun)(cun)(cun)(cun)(cun)適合(he)別墅使(shi)用。

液晶電視尺寸計算方法

以32寸液晶電(dian)(dian)視(shi)(shi)機為例，其尺寸計(ji)算方法：以1 英寸= 2.539999918 厘米，以電(dian)(dian)視(shi)(shi)平面對角線計(ji)算為準：32*2.539999918 =81.27997376厘米，按(an)常見4:3為比例計(ji)算，一(yi)般是長=65.024cm，寬(kuan)=48.768cm ；若按(an)16:9為比例計(ji)算，一(yi)般是69=cm，寬(kuan)=39cm。

電視機黑屏是怎么回事

如果電(dian)(dian)(dian)(dian)(dian)視(shi)(shi)機(ji)的電(dian)(dian)(dian)(dian)(dian)源(yuan)指示(shi)(shi)燈(deng)滅，則可能是(shi)電(dian)(dian)(dian)(dian)(dian)視(shi)(shi)機(ji)的電(dian)(dian)(dian)(dian)(dian)源(yuan)連(lian)接有問(wen)題，導致(zhi)突然斷電(dian)(dian)(dian)(dian)(dian)黑屏。 比(bi)如電(dian)(dian)(dian)(dian)(dian)源(yuan)插頭松動、電(dian)(dian)(dian)(dian)(dian)源(yuan)線故障(zhang)等，可以逐一排查，找出問(wen)題進(jin)行相應的處理。 如果電(dian)(dian)(dian)(dian)(dian)視(shi)(shi)機(ji)電(dian)(dian)(dian)(dian)(dian)源(yuan)指示(shi)(shi)燈(deng)亮，則可能是(shi)用戶(hu)誤(wu)按遙控器(qi)的待機(ji)鍵使電(dian)(dian)(dian)(dian)(dian)視(shi)(shi)機(ji)進(jin)入待機(ji)狀態，所以顯(xian)示(shi)(shi)黑屏，只要(yao)重新按下待機(ji)鍵即可。 如果以上方(fang)法排查后(hou)，電(dian)(dian)(dian)(dian)(dian)視(shi)(shi)機(ji)仍然黑屏，有可能是(shi)硬件故障(zhang)引(yin)起的。比(bi)如電(dian)(dian)(dian)(dian)(dian)源(yuan)模(mo)塊故障(zhang)、開(kai)關電(dian)(dian)(dian)(dian)(dian)路(lu)短路(lu)或開(kai)路(lu)、高(gao)壓板(ban)故障(zhang)、液晶屏或屏線故障(zhang)、主板(ban)芯片或者(zhe)其他零部(bu)件故障(zhang)等，這時候需要(yao)聯(lian)系電(dian)(dian)(dian)(dian)(dian)視(shi)(shi)機(ji)的售(shou)后(hou)服務對電(dian)(dian)(dian)(dian)(dian)視(shi)(shi)機(ji)進(jin)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。
