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

電視機尺寸多大合適

液晶電(dian)(dian)視(shi)機常見的尺寸(cun)(cun)(cun)(cun)有32寸(cun)(cun)(cun)(cun)、42寸(cun)(cun)(cun)(cun)、46寸(cun)(cun)(cun)(cun)、47寸(cun)(cun)(cun)(cun)、50寸(cun)(cun)(cun)(cun)、60寸(cun)(cun)(cun)(cun)。如(ru)果(guo)是(shi)(shi)臥室的電(dian)(dian)視(shi)機，那么32寸(cun)(cun)(cun)(cun)、42寸(cun)(cun)(cun)(cun)是(shi)(shi)不錯的選擇(ze)。如(ru)果(guo)是(shi)(shi)放置在客(ke)廳，客(ke)廳又不是(shi)(shi)很大，42寸(cun)(cun)(cun)(cun)、46寸(cun)(cun)(cun)(cun)、47寸(cun)(cun)(cun)(cun)的電(dian)(dian)視(shi)機就很適(shi)合。如(ru)果(guo)客(ke)廳面積(ji)很大，可以選50寸(cun)(cun)(cun)(cun)的電(dian)(dian)視(shi)機。而60寸(cun)(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(cun)液(ye)晶(jing)電視機為(wei)例(li)，其尺寸(cun)計算方法(fa)：以(yi)1 英(ying)寸(cun)= 2.539999918 厘米，以(yi)電視平(ping)面對角線計算為(wei)準：32*2.539999918 =81.27997376厘米，按常(chang)見4:3為(wei)比例(li)計算，一(yi)般(ban)是(shi)長=65.024cm，寬=48.768cm ；若按16:9為(wei)比例(li)計算，一(yi)般(ban)是(shi)69=cm，寬=39cm。

電視機黑屏是怎么回事

如(ru)(ru)果電(dian)(dian)(dian)(dian)(dian)(dian)視機(ji)的(de)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)指(zhi)示(shi)(shi)燈(deng)(deng)滅(mie)，則可能是(shi)(shi)電(dian)(dian)(dian)(dian)(dian)(dian)視機(ji)的(de)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)連接有問(wen)題，導致突然斷電(dian)(dian)(dian)(dian)(dian)(dian)黑屏(ping)(ping)(ping)(ping)。 比如(ru)(ru)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)插頭(tou)松(song)動、電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)線故(gu)障等，可以逐一(yi)排查，找出問(wen)題進行相應的(de)處理(li)。 如(ru)(ru)果電(dian)(dian)(dian)(dian)(dian)(dian)視機(ji)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)指(zhi)示(shi)(shi)燈(deng)(deng)亮，則可能是(shi)(shi)用戶(hu)誤按遙控器的(de)待(dai)機(ji)鍵(jian)使電(dian)(dian)(dian)(dian)(dian)(dian)視機(ji)進入待(dai)機(ji)狀態，所(suo)以顯(xian)示(shi)(shi)黑屏(ping)(ping)(ping)(ping)，只要重(zhong)新按下待(dai)機(ji)鍵(jian)即可。 如(ru)(ru)果以上方法排查后，電(dian)(dian)(dian)(dian)(dian)(dian)視機(ji)仍(reng)然黑屏(ping)(ping)(ping)(ping)，有可能是(shi)(shi)硬(ying)件故(gu)障引(yin)起的(de)。比如(ru)(ru)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)模塊故(gu)障、開(kai)(kai)關電(dian)(dian)(dian)(dian)(dian)(dian)路短路或(huo)開(kai)(kai)路、高壓板(ban)故(gu)障、液晶屏(ping)(ping)(ping)(ping)或(huo)屏(ping)(ping)(ping)(ping)線故(gu)障、主板(ban)芯片(pian)或(huo)者其他零部件故(gu)障等，這(zhe)時候需要聯系電(dian)(dian)(dian)(dian)(dian)(dian)視機(ji)的(de)售后服務對電(dian)(dian)(dian)(dian)(dian)(dian)視機(ji)進行檢修才能解(jie)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。
