就拿海爾電視來說，電視機沒有圖像的原因如下：

　　1、假如(ru)電(dian)(dian)視(shi)機沒有圖像，有可(ke)能(neng)是高頻或中放電(dian)(dian)路有問題(ti)，需要(yao)聯系專業人員上門維修，這(zhe)樣才能(neng)解決(jue)電(dian)(dian)視(shi)機沒有圖像的問題(ti)。

　　2、如果掃描(miao)電(dian)路中(zhong)有元件出現(xian)虛焊的現(xian)象(xiang)，會導致(zhi)電(dian)視機沒有圖象(xiang)，需要及(ji)時修理，這(zhe)樣才能解決問題(ti)。

　　3、如(ru)果電(dian)視(shi)機(ji)(ji)沒有(you)(you)圖像，有(you)(you)可能是電(dian)視(shi)機(ji)(ji)沒有(you)(you)接通電(dian)源(yuan)所致，可將電(dian)視(shi)機(ji)(ji)接通電(dian)源(yuan)，打開電(dian)視(shi)后(hou)會出現圖像。

　　4、正在看電(dian)(dian)(dian)(dian)視時不(bu)小心按(an)了(le)(le)電(dian)(dian)(dian)(dian)視機遙控器(qi)的“電(dian)(dian)(dian)(dian)源(yuan)”鍵(jian)，關掉了(le)(le)電(dian)(dian)(dian)(dian)視屏幕(mu)(mu)顯示(shi)功能，使(shi)電(dian)(dian)(dian)(dian)視“處(chu)于待(dai)機狀態”，這樣電(dian)(dian)(dian)(dian)視機就沒有圖象，可(ke)再(zai)按(an)一次(ci)“電(dian)(dian)(dian)(dian)源(yuan)”鍵(jian)啟動(dong)屏幕(mu)(mu)，從(cong)而恢復正常(chang)。

　　5、如果電(dian)(dian)視機(ji)硬件(jian)出現故(gu)(gu)(gu)障(zhang)(zhang)、主板開關電(dian)(dian)路故(gu)(gu)(gu)障(zhang)(zhang)、屏幕排(pai)線(xian)故(gu)(gu)(gu)障(zhang)(zhang)、屏幕故(gu)(gu)(gu)障(zhang)(zhang)、顯像(xiang)管和底(di)座故(gu)(gu)(gu)障(zhang)(zhang)、其它部件(jian)故(gu)(gu)(gu)障(zhang)(zhang)等問(wen)題(ti)，都會導致電(dian)(dian)視機(ji)沒有圖像(xiang)，需要(yao)聯系電(dian)(dian)視機(ji)的售(shou)后服(fu)務來修復。
