檢修手段：1非常仔(zi)細查(cha)看(kan)手機電(dian)(dian)(dian)路(lu)設計板上端(duan)的(de)有(you)(you)(you)(you)(you)(you)幾(ji)個部件(jian)(jian)(jian)，看(kan)有(you)(you)(you)(you)(you)(you)無在這一(yi)些部件(jian)(jian)(jian)的(de)外觀(guan)如果沒(mei)(mei)有(you)(you)(you)(you)(you)(you)有(you)(you)(you)(you)(you)(you)被(bei)燒(shao)糊, 到底有(you)(you)(you)(you)(you)(you)也就沒(mei)(mei)有(you)(you)(you)(you)(you)(you)有(you)(you)(you)(you)(you)(you)電(dian)(dian)(dian)解拋光(guang)液上溢，聞(wen)一(yi)聞(wen)到底有(you)(you)(you)(you)(you)(you)也就沒(mei)(mei)有(you)(you)(you)(you)(you)(you)有(you)(you)(you)(you)(you)(you)有(you)(you)(you)(you)(you)(you)異味。經(jing)看(kan)，聞(wen)接(jie)下來，再(zai)換萬用表使用檢查(cha)報告。先測(ce)量方法兩(liang)下電(dian)(dian)(dian)壓(ya)(ya)輸(shu)(shu)人高端(duan)的(de)熱(re)敏電(dian)(dian)(dian)阻(zu)值(zhi)，若大(da)于200K，則說明書怎么寫(xie)后臺開發有(you)(you)(you)(you)(you)(you)輪廓(kuo)斷(duan)路(lu)現象，并且各分為自(zi)動測(ce)量四只整流(liu)電(dian)(dian)(dian)感正，選擇性阻(zu)值(zhi)和倆個限流(liu)阻(zu)值(zhi)的(de)阻(zu)值(zhi)，看(kan)其(qi)有(you)(you)(you)(you)(you)(you)沒(mei)(mei)有(you)(you)(you)(you)(you)(you)斷(duan)路(lu)或(huo)損壞(huai);接(jie)下來再(zai)測(ce)量一(yi)個電(dian)(dian)(dian)原濾波(bo)電(dian)(dian)(dian)阻(zu)有(you)(you)(you)(you)(you)(you)沒(mei)(mei)有(you)(you)(you)(you)(you)(you)能實行普(pu)通 充熱(re)擊(ji)(ji)穿(chuan)，再(zai)就測(ce)量一(yi)個面板開關最大(da)功率管(guan)(guan)有(you)(you)(you)(you)(you)(you)沒(mei)(mei)有(you)(you)(you)(you)(you)(you)熱(re)擊(ji)(ji)穿(chuan)壞(huai)掉，及(ji)及(ji)UC3842自(zi)己，及(ji)較近(jin)構件(jian)(jian)(jian)可否電(dian)(dian)(dian)壓(ya)(ya)擊(ji)(ji)穿(chuan)，跳閘(zha)等。必(bi)須 這說明的(de)這一(yi)點(dian)是：因(yin)是在路(lu)衡量，有(you)(you)(you)(you)(you)(you)已(yi)經(jing)會(hui)(hui)使衡量沒(mei)(mei)想到有(you)(you)(you)(you)(you)(you)誤，會(hui)(hui)導致(zhi)誤判。從而必(bi)須時可把(ba)元(yuan)(yuan)(yuan)器材(cai)焊過來再(zai)完成衡量。假若從未找不到出現條(tiao)件(jian)(jian)(jian)則衡量下讀取電(dian)(dian)(dian)壓(ya)(ya)線(xian)及(ji)的(de)輸(shu)(shu)出電(dian)(dian)(dian)壓(ya)(ya)線(xian)可否組織結構跳閘(zha)。大(da)部分條(tiao)件(jian)(jian)(jian)下，融斷(duan)器融斷(duan)報警，整流(liu)場效應管(guan)(guan)，電(dian)(dian)(dian)壓(ya)(ya)濾波(bo)電(dian)(dian)(dian)感，啟閉耗油率管(guan)(guan)，UC3842是易損件(jian)(jian)(jian)，搞壞(huai)的(de)的(de)幾(ji)率多達95%綜上所述(shu)，大(da)部分重在檢查(cha)報告兩(liang)下或(huo)者元(yuan)(yuan)(yuan)電(dian)(dian)(dian)器元(yuan)(yuan)(yuan)件(jian)(jian)(jian)封裝，就可很更易確診或(huo)者告警。
問題現象(xiang)二(er)：水冷(leng)散(san)熱排風(feng)扇不(bu)轉
這(zhe)(zhe)(zhe)款錯誤(wu)代碼其原因(yin)大(da)部分是隨著保(bao)持葉(xie)輪的(de)晶體管(8550或(huo)8050)毀(hui)損(sun)，還(huan)有(you)電扇一種(zhong)毀(hui)損(sun)或(huo)葉(xie)輪被污物卡住。但有(you)打(da)(da)開(kai)電源線(xian)按鈕(niu)開(kai)關(guan)中(zhong)用(yong)到(dao)的(de)是智力風扇，散熱(re)處理，這(zhe)(zhe)(zhe)對用(yong)到(dao)這(zhe)(zhe)(zhe)類策略風扇，散熱(re)處理的(de)打(da)(da)開(kai)電源線(xian)按鈕(niu)開(kai)關(guan)，熱(re)敏阻(zu)值毀(hui)損(sun)的(de)概率統(tong)計是大(da)的(de)。
維護(hu)形式：首選(xuan)用(yong)萬用(yong)表測(ce)(ce)(ce)量方法了解(jie)把握散(san)(san)熱(re)器(qi)(qi)換氣(qi)扇(shan)的三級(ji)管有沒有毀(hui)(hui)壞(huai)，若精確(que)測(ce)(ce)(ce)量此管未(wei)毀(hui)(hui)壞(huai)那便有能夠是散(san)(san)熱(re)器(qi)(qi)換氣(qi)扇(shan)本就(jiu)毀(hui)(hui)壞(huai)。可(ke)(ke)能把散(san)(san)熱(re)器(qi)(qi)換氣(qi)扇(shan)從電(dian)(dian)(dian)(dian)路(lu)(lu)設計板上(shang)拔完成，另(ling)一(yi)接上(shang)去(qu)一(yi)些12V的整流電(dian)(dian)(dian)(dian)(準備正反極(ji))，看(kan)可(ke)(ke)不可(ke)(ke)以晃(huang)動，并看(kan)有何(he)殘留(liu)物卡(ka)住(zhu)。若偏移一(yi)兩(liang)下排小空調風扇(shan)的電(dian)(dian)(dian)(dian)覽(lan)電(dian)(dian)(dian)(dian)路(lu)(lu)，排小空調風扇(shan)就(jiu)晃(huang)動，則就(jiu)說明電(dian)(dian)(dian)(dian)覽(lan)電(dian)(dian)(dian)(dian)路(lu)(lu)企(qi)業內部有寬帶掉線或插頭接受黑(hei)心。若仍不晃(huang)動，則排小空調風扇(shan)必壞(huai)。相(xiang)對采取(qu)智能化熱(re)管散(san)(san)熱(re)的按(an)鈕開關供電(dian)(dian)(dian)(dian)說，除(chu)按(an)這(zhe)些檢測(ce)(ce)(ce)外，還(huan)應檢測(ce)(ce)(ce)一(yi)下吧熱(re)敏電(dian)(dian)(dian)(dian)容(rong)(rong)器(qi)(qi)可(ke)(ke)不可(ke)(ke)以黑(hei)心或影(ying)響，開焊等(deng)。但(dan)要注重(zhong)此熱(re)敏電(dian)(dian)(dian)(dian)容(rong)(rong)器(qi)(qi)為負(fu)溫比率(lv)的熱(re)敏電(dian)(dian)(dian)(dian)容(rong)(rong)器(qi)(qi)，換個時先注重(zhong)。
