福州電動門遙控器如何維修
  故(gu)障一： 遙控(kong)器全部按鍵起作用
  分析與檢(jian)(jian)修(xiu)：遙控器(qi)全(quan)(quan)部(bu)按鍵起作用(yong)原絕(jue)數晶(jing)(jing)振(zhen)損壞所致曾經跌落(luo)或(huo)用(yong)收音機檢(jian)(jian)查完全(quan)(quan)沒嘟嘟聲(sheng)，直接更(geng)換新(xin)晶(jing)(jing)振(zhen)試更(geng)換新(xin)晶(jing)(jing)振(zhen)能排除故障(zhang)應先測量晶(jing)(jing)振(zhen)兩(liang)(liang)端(duan)電壓按任何鍵晶(jing)(jing)振(zhen)兩(liang)(liang)端(duan)明(ming)顯電壓變(bian)化說明(ming)振(zhen)蕩器(qi)能產(chan)脈沖信號(hao)其檢(jian)(jian)查集(ji)塊遙控信號(hao)輸端(duan)否相較微弱電壓變(bian)化變(bian)化則應檢(jian)(jian)查推三(san)極(ji)管紅(hong)外(wai)發射(she)管否損壞否則數集(ji)塊良。

  故障二： 別按鍵起作(zuo)用
  分析與檢修：該現象說明遙控(kong)器整(zheng)體別按(an)鍵(jian)起作用原按(an)鍵(jian)電路觸(chu)點能(neng)效導通數遙控(kong)器內線(xian)路板觸(chu)點污物(wu)使接(jie)(jie)觸(chu)電阻增或(huo)能(neng)接(jie)(jie)通用棉(mian)花蘸水酒精擦拭(shi)碳膜觸(chu)點能(neng)太用力(li)防碳膜層磨(mo)損(sun)或(huo)脫落導電橡(xiang)(xiang)膠(jiao)化或(huo)磨(mo)損(sun)導致別鍵(jian)起作用要導電橡(xiang)(xiang)膠(jiao)接(jie)(jie)觸(chu)點貼(tie)香煙盒錫(xi)紙（鋁箔(bo)干膠(jiao)）試(shi)辦(ban)能(neng)使遙控(kong)器恢(hui)復工作應檢查集塊應鍵(jian)控(kong)信號輸入、輸端觸(chu)點線(xian)路否裂紋或(huo)接(jie)(jie)觸(chu)良特別碳膜觸(chu)點與電路線(xian)連接(jie)(jie)處必(bi)要更換集塊試(shi)
  故障三： 遙控(kong)器(qi)遙控(kong)距離較短
  析與檢修：首(shou)先應判別遙(yao)(yao)控接收電(dian)路否工作用(yong)同牌(pai)同規格(ge)遙(yao)(yao)控器(qi)試(shi)機加(jia)比較遙(yao)(yao)控接收機應檢查遙(yao)(yao)控器(qi)兩(liang)面：集(ji)塊電(dian)源輸(shu)入端３Ｖ電(dian)壓(ya)否通電(dian)池電(dian)壓(ya)足遙(yao)(yao)控器(qi)發射(she)能力降低見原二檢查遙(yao)(yao)控器(qi)推三極管及(ji)紅外發射(she)管否良(liang)更換(huan)試(shi)驗
  故障(zhang)四： 按壓任何鍵(jian)均執行某種功能(neng)
  析與檢修：通由(you)于線(xian)路板執行某種(zhong)功能按(an)鍵(jian)處叉指觸點或引線(xian)間漏電或短路
