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2.5m;42寸建議(yi)觀看距離為3.0m;46寸建議觀(guan)看距離為3.5m;52寸建議觀看距離(li)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)視機常見的(de)(de)尺(chi)寸(cun)(cun)(cun)有32寸(cun)(cun)(cun)、42寸(cun)(cun)(cun)、46寸(cun)(cun)(cun)、47寸(cun)(cun)(cun)、50寸(cun)(cun)(cun)、60寸(cun)(cun)(cun)。如(ru)果是(shi)臥室的(de)(de)電(dian)視機,那么32寸(cun)(cun)(cun)、42寸(cun)(cun)(cun)是(shi)不(bu)錯的(de)(de)選擇。如(ru)果是(shi)放置在客廳,客廳又不(bu)是(shi)很(hen)(hen)大,42寸(cun)(cun)(cun)、46寸(cun)(cun)(cun)、47寸(cun)(cun)(cun)的(de)(de)電(dian)視機就(jiu)很(hen)(hen)適(shi)合。如(ru)果客廳面積很(hen)(hen)大,可以(yi)選50寸(cun)(cun)(cun)的(de)(de)電(dian)視機。而60寸(cun)(cun)(cun)適(shi)合別墅使用(yong)。
液晶電視尺寸計算方法
以(yi)32寸液晶電視機為(wei)例,其尺寸計(ji)算方法:以(yi)1 英寸= 2.539999918 厘米,以(yi)電視平面對角線計(ji)算為(wei)準:32*2.539999918 =81.27997376厘米,按常見(jian)4:3為(wei)比(bi)例計(ji)算,一般是(shi)長=65.024cm,寬(kuan)=48.768cm ;若按16:9為(wei)比(bi)例計(ji)算,一般是(shi)69=cm,寬(kuan)=39cm。
電視機黑屏是怎么回事
如(ru)(ru)果電(dian)(dian)(dian)(dian)視(shi)機(ji)的(de)(de)電(dian)(dian)(dian)(dian)源(yuan)指示燈(deng)滅,則(ze)可(ke)能(neng)(neng)是(shi)電(dian)(dian)(dian)(dian)視(shi)機(ji)的(de)(de)電(dian)(dian)(dian)(dian)源(yuan)連(lian)接有問題(ti),導致突然(ran)斷電(dian)(dian)(dian)(dian)黑屏(ping)。 比如(ru)(ru)電(dian)(dian)(dian)(dian)源(yuan)插頭(tou)松(song)動、電(dian)(dian)(dian)(dian)源(yuan)線故障(zhang)(zhang)等,可(ke)以逐一(yi)排(pai)查,找出(chu)問題(ti)進(jin)行相應的(de)(de)處理。 如(ru)(ru)果電(dian)(dian)(dian)(dian)視(shi)機(ji)電(dian)(dian)(dian)(dian)源(yuan)指示燈(deng)亮,則(ze)可(ke)能(neng)(neng)是(shi)用戶誤(wu)按遙控器的(de)(de)待機(ji)鍵使(shi)電(dian)(dian)(dian)(dian)視(shi)機(ji)進(jin)入待機(ji)狀(zhuang)態,所(suo)以顯(xian)示黑屏(ping),只(zhi)要(yao)重新按下待機(ji)鍵即可(ke)。 如(ru)(ru)果以上(shang)方法排(pai)查后,電(dian)(dian)(dian)(dian)視(shi)機(ji)仍然(ran)黑屏(ping),有可(ke)能(neng)(neng)是(shi)硬件故障(zhang)(zhang)引起的(de)(de)。比如(ru)(ru)電(dian)(dian)(dian)(dian)源(yuan)模塊故障(zhang)(zhang)、開關電(dian)(dian)(dian)(dian)路短路或開路、高(gao)壓板(ban)故障(zhang)(zhang)、液晶屏(ping)或屏(ping)線故障(zhang)(zhang)、主板(ban)芯片或者其(qi)他(ta)零部(bu)件故障(zhang)(zhang)等,這時候需要(yao)聯系電(dian)(dian)(dian)(dian)視(shi)機(ji)的(de)(de)售后服務對電(dian)(dian)(dian)(dian)視(shi)機(ji)進(jin)行檢修才能(neng)(neng)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。
