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(li)為2.5m；42寸建議觀看距離為3.0m；46寸建議觀(guan)看距離為3.5m；52寸建(jian)議觀看距離為4.0m；60寸建議觀(guan)看距離為4.5m。

電視機尺寸多大合適

液晶電(dian)視機(ji)(ji)常見的(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(guo)是(shi)(shi)臥(wo)室的(de)電(dian)視機(ji)(ji)，那么32寸(cun)(cun)、42寸(cun)(cun)是(shi)(shi)不錯(cuo)的(de)選(xuan)(xuan)擇。如(ru)果(guo)是(shi)(shi)放(fang)置在(zai)客(ke)廳(ting)(ting)，客(ke)廳(ting)(ting)又(you)不是(shi)(shi)很大，42寸(cun)(cun)、46寸(cun)(cun)、47寸(cun)(cun)的(de)電(dian)視機(ji)(ji)就很適(shi)合。如(ru)果(guo)客(ke)廳(ting)(ting)面(mian)積很大，可以選(xuan)(xuan)50寸(cun)(cun)的(de)電(dian)視機(ji)(ji)。而60寸(cun)(cun)適(shi)合別墅使用。

液晶電視尺寸計算方法

以(yi)32寸(cun)液晶(jing)電(dian)視機為例，其尺(chi)寸(cun)計(ji)算(suan)(suan)方(fang)法：以(yi)1 英寸(cun)= 2.539999918 厘米，以(yi)電(dian)視平面對角(jiao)線(xian)計(ji)算(suan)(suan)為準(zhun)：32*2.539999918 =81.27997376厘米，按常(chang)見4:3為比(bi)例計(ji)算(suan)(suan)，一(yi)般(ban)是長(chang)=65.024cm，寬=48.768cm ；若按16:9為比(bi)例計(ji)算(suan)(suan)，一(yi)般(ban)是69=cm，寬=39cm。

電視機黑屏是怎么回事

如(ru)(ru)果電(dian)(dian)(dian)(dian)(dian)視(shi)(shi)(shi)機(ji)(ji)(ji)(ji)的(de)電(dian)(dian)(dian)(dian)(dian)源(yuan)指示燈(deng)滅，則可(ke)(ke)(ke)能(neng)是(shi)電(dian)(dian)(dian)(dian)(dian)視(shi)(shi)(shi)機(ji)(ji)(ji)(ji)的(de)電(dian)(dian)(dian)(dian)(dian)源(yuan)連接有(you)問題，導(dao)致突然斷電(dian)(dian)(dian)(dian)(dian)黑(hei)(hei)屏。 比如(ru)(ru)電(dian)(dian)(dian)(dian)(dian)源(yuan)插頭松(song)動、電(dian)(dian)(dian)(dian)(dian)源(yuan)線(xian)(xian)故(gu)(gu)(gu)障(zhang)等(deng)，可(ke)(ke)(ke)以逐一(yi)排查，找出問題進(jin)行相應的(de)處理。 如(ru)(ru)果電(dian)(dian)(dian)(dian)(dian)視(shi)(shi)(shi)機(ji)(ji)(ji)(ji)電(dian)(dian)(dian)(dian)(dian)源(yuan)指示燈(deng)亮，則可(ke)(ke)(ke)能(neng)是(shi)用(yong)戶誤按遙控器的(de)待機(ji)(ji)(ji)(ji)鍵使電(dian)(dian)(dian)(dian)(dian)視(shi)(shi)(shi)機(ji)(ji)(ji)(ji)進(jin)入(ru)待機(ji)(ji)(ji)(ji)狀(zhuang)態，所以顯示黑(hei)(hei)屏，只要重新(xin)按下(xia)待機(ji)(ji)(ji)(ji)鍵即可(ke)(ke)(ke)。 如(ru)(ru)果以上(shang)方法排查后(hou)，電(dian)(dian)(dian)(dian)(dian)視(shi)(shi)(shi)機(ji)(ji)(ji)(ji)仍然黑(hei)(hei)屏，有(you)可(ke)(ke)(ke)能(neng)是(shi)硬件故(gu)(gu)(gu)障(zhang)引(yin)起的(de)。比如(ru)(ru)電(dian)(dian)(dian)(dian)(dian)源(yuan)模(mo)塊(kuai)故(gu)(gu)(gu)障(zhang)、開(kai)關電(dian)(dian)(dian)(dian)(dian)路短路或(huo)(huo)開(kai)路、高壓板(ban)(ban)故(gu)(gu)(gu)障(zhang)、液晶屏或(huo)(huo)屏線(xian)(xian)故(gu)(gu)(gu)障(zhang)、主板(ban)(ban)芯片或(huo)(huo)者其(qi)他零(ling)部件故(gu)(gu)(gu)障(zhang)等(deng)，這時候(hou)需要聯系電(dian)(dian)(dian)(dian)(dian)視(shi)(shi)(shi)機(ji)(ji)(ji)(ji)的(de)售后(hou)服(fu)務(wu)對電(dian)(dian)(dian)(dian)(dian)視(shi)(shi)(shi)機(ji)(ji)(ji)(ji)進(jin)行檢修才(cai)能(neng)解決。
