依賴電源作為基本工作條件來完成自身正常工作的設(shè)備均為有源器件，它主要是前端設(shè)備、傳輸網(wǎng)絡(luò)中的放大器、過流分支分配器、饋電放大器和光發(fā)射機(jī)、接收機(jī)等。而放大器是接入網(wǎng)中用得多、廣泛的有源器件，它的作用是當(dāng)電視信號從電纜中傳輸一定距離后，因電纜的傳輸衰減特性，使電視信號越耒越低，當(dāng)?shù)偷揭?guī)定電平時，必須再加一只放大器，將信號放大后再往下傳送。起到信號放大作用和向遠(yuǎn)距離傳送電視信號的目的。

①打雷時，在供電線路上很容易產(chǎn)生很高的意外過電壓將放大器擊壞，可在放大器電源上加裝一只防雷突波器來達(dá)到保護(hù)放大器不致燒壞的目的。
 
②放大器的供電電壓過低，或者電源插座接觸不良，放大器長期工作在較大電流下，使放大器燒壞，采取的措施是選用開關(guān)電源的放大器，拓寬供電電源的范圍，保證放大器正常工作，信號質(zhì)量不變，特別是農(nóng)村電源線路不規(guī)范，電壓低的和不穩(wěn)定的較普遍，放大器損壞的也較多，這些地方也可選用開關(guān)電源放大器。
 
③因供電線路各相電源負(fù)荷不平衡，使中心線有電流通過，一旦中心線燒斷，使相電壓變成線電壓，達(dá)到380V左右，由于各相所帶負(fù)荷不等，因此各相間電壓也會有高低不等，這時正在工作的放大器會因電壓升高而燒壞。
 
④放大器電源中的濾波電容因長時間工作，電容干枯、老化、容量變小，在電視屏幕上產(chǎn)生50Hz上下移動的交流橫道線，使畫面不干凈，這是維修中常見到的故障。
 
⑤放大器內(nèi)部散熱不好，使電平出現(xiàn)波動，原因是可調(diào)部位是金屬片，放大器溫度過高時，非常容易使可調(diào)金屬片熱脹冷縮，造成接觸不良，使電平不穩(wěn)定。
 
⑥使用一定年限的放大器指標(biāo)會變壞，元件老化，特別是前幾級的放大器一定要換掉，以免影響傳輸質(zhì)量；出故障經(jīng)修復(fù)后的放大器不能用在主干線和支干線的前幾級；可用在戶數(shù)較少的終端上，一旦出故障，也不會影響大面積用戶收看電視。
 
⑦放大器本身溫度過高，加上安裝的位置又是太陽直射的地方，也容易使放大器保險燒斷，中斷電視信號。
