1. Indlela yokucindezela iphaneli isebenzisa umsebenzi weswishi ngayinye neknobhu evezwe ngaphandle kwephaneli kagesi, ikhonsoli noma umshini ukuhlola nokwahlulela cishe indawo yephutha.Isibonelo, umsindo we-TV awuvamile ngezinye izikhathi, futhi ivolumu yevolumu iyalungiswa ukuze ivele“Kluck”umsindo ohambisana nomsindo ongavamile, khona-ke kungaziwa ukuthi i-potentiometer yevolumu inokuxhumana okungalungile.
2. Indlela yokuhlola eqondile ukuhlola nokwahlulela indawo yephutha ngokubona, ukuthinta, ukuzwa nokuhogela.Le ndlela ifaneleka ngokukhethekile amaphutha asobala njengokushisa, iphunga elishisayo, iphunga le-ozone nomsindo ongavamile.Ngokwesibonelo, kukhona a“qhekeza”umsindo ngaphakathi kwe-TV ngemva kokuyivula, isithombe sigxuma ngomsindo futhi iphunga elinamandla le-ozone lizwakala, khona-ke kungahlulelwa ukuthi i-transformer ephumayo yomugqa noma ingxenye ye-voltage ephezulu iyavutha.
3. Indlela yokulinganisa i-voltage ukuhlola amandla kagesi kanye ne-voltage yezingxenye ezifanele ngokusebenzisa i-multimeter, ikakhulukazi i-voltage ezindaweni ezibalulekile.Le ndlela iyindlela yokuhlola eyisisekelo futhi evame ukusetshenziswa kakhulu yokunakekelwa kwempahla yasendlini.
4. Indlela yokulinganisa yamanje kagesi iwukukala ingqikithi yamanje kanye namandla asebenzayo ama-transistors nezingxenye ngokusebenzisa uhla olufanele lwamanje lwe-multimeter, ukuze wahlulele indawo enephutha ngokushesha.Isibonelo, i-TV ivamise ukushiswa ngefuse ye-DC futhi isamba samanje samandla kagesi alinganiselwe sikhulu kunevelu evamile, isifunda sesiteji sokuphuma komugqa siyanqanyulwa futhi okwamanje kubuyele kokujwayelekile, bese kunganqunywa ukuthi iphutha isesigabeni sokuphuma komugqa namasekhethi alandelayo.
5. Indlela yokulinganisa ukumelana iwukwahlulela indawo yephutha ngokulinganisa inani lokumelana nokumelana, i-capacitance, inductance, ikhoyili, i-transistor kanye ne-block ehlanganisiwe.
6. Indlela ye-short-circuit ibhekisela endleleni ye-AC ye-short-circuit, esebenza kahle kakhulu ekunqumeni ububanzi bomsindo we-steamboat, umsindo wokuhewula nomsindo.Isibonelo, uma ufuna ukwahlulela iphutha lokukhala lomsakazo, ungasebenzisa i-0.1μI-capacitor ka-F ukuze ijikeleze isikhashana abaqoqi beshubhu yokuguqula, ishubhu lokuqala lokukhulisa elimaphakathi nendawo kanye neshubhu lesibili lokukhulisa eliphakathi nendawo phansi, ngokulandelana.Ukukhala kuyanyamalala esigabeni esithile sesifunda esifushane, iphutha lenzeka kulesi sigaba.
7. Indlela yokunqamula isiyingi iwukucindezela uhla lwamaphutha ngokusika isekethe ethile noma ukukhulula ingxenye ethile nezintambo.Isibonelo, ingqikithi yamanje yezinto ezisebenza ngogesi inkulu kakhulu, ingxenye esolisayo yesekhethi inganqanyulwa kancane kancane.Iphutha lizoba sesiteji lapho i-current ibuyela kwesijwayelekile uma inqanyuliwe.Le ndlela ivame ukusetshenziselwa ukulungisa iphutha lokushiswa kwamanje ngokweqile kanye ne-fuse.
8. Indlela yokungqongqoza ukwahlulela indawo enephutha ngokusebenzisa isibambo se-screwdriver esincane noma isando sokhuni ukuze ungqongqoze kancane indawo ethile ebhodini lesifunda futhi ubuke isimo (Qaphela: ngokuvamile akulula ukungqongqoza ingxenye ene-voltage ephezulu. ).Le ndlela ifaneleka ngokukhethekile ukuhlola iphutha le-welding yamanga kanye nokuxhumana okungalungile.Isibonelo, awukho umsindo esithombeni se-TV ngezinye izikhathi, ungangqongqoza ngobumnene kugobolondo le-TV ngesandla sakho, futhi iphutha liyabonakala.Vula ikhava yangemuva ye-TV, khipha ibhodi lesekhethi, bese ungqongqoza ngobumnene izingxenye ezisolisayo ngesibambo se-screwdriver.Iphutha likule ngxenye lapho iphutha libonakala khona uma ingqongqozwa.
9. Ukushintsha indlela yokuhlola wukushintsha ingxenye ethathwa njengenephutha ngokusebenzisa ingxenye enhle.Le ndlela ilula futhi kulula ukuyisebenzisa, futhi ngokuvamile inekabili umphumela ngesigamu somzamo..Ivamise ukusetshenziselwa ukufaka esikhundleni seshuna, i-transformer ephumayo yomugqa, i-capacitor engaphansi kuka-0.1μF, transistor, block edidiyelwe nokunye.
10. Indlela yokujova isignali ukuthola indawo enephutha ngokujova isignali ye-generator yesignali kusekethe enephutha.Le ndlela ngokuvamile isetshenziselwa ukulungisa iphutha eliyinkimbinkimbi.
11. Indlela yokuphazamisa wukwahlulela indawo enephutha ngokuthiusebenzisaingxenye yensimbi ye-screwdriver kanye nama-tweezers ukuze uthinte izindawo zokuhlonza ezifanele, buka impendulo ye-clutter esikrinini futhi uzwe“Kluck”umsindo wecilongo.Le ndlela ivame ukusetshenziselwa ukuhlola isiteshi somphakathi, isiteshi sesithombe nesiteshi somsindo.Isibonelo, asikho isithombe noma iphutha lomsindo elitholiwe, thatha i-screwdriver ukuze uthinte isisekelo sokuqala sokukhulisa esimaphakathi.Uma kukhona ukusabela kwemfuhlumfuhlu esikrinini futhi uphondo lunalo“Kluck”umsindo, ukhombisa ukuthi umjikelezo ujwayelekile ngemuva kokukhulisa okuphakathi, ngakho-ke iphutha likushuna noma uthi.
12. Indlela yokuqhathanisa iwukuthola indawo enephutha ngokuqhathanisa i-voltage, i-waveform namanye amapharamitha omshini ojwayelekile wemodeli efanayo nomshini onephutha.Le ndlela ifaneleka kakhulu lapho umdwebo wesifunda ungatholakali.
13. Indlela yokushisa ukwahlulela ngokushesha indawo enephutha ngokushisisa ingxenye esolisayo, ukuze kusheshiswe“ukufa”kwengxenye enjalo.Isibonelo, ububanzi bomugqa we-TV bujwayelekile uma isanda kuvulwa, futhi ububanzi bomugqa buhlehla ngemva kwemizuzu embalwa, igobolondo leshubhu yokukhipha umugqa liphenduka libe phuzi futhi ishuni yomugqa iyashisa, bese ungathatha i-soldering. insimbi ukuze usondele kushubhu kalayini ukuze uyishise.Uma ububanzi bomugqa buqhubeka buhlehla, kungahlulelwa ukuthi ishubhu yomugqa inephutha.
14. Indlela yokupholisa ukwahlulela ngokushesha indawo enephutha ngokupholisa izingxenye ezisolisayo.Le ndlela isetshenziselwa iphutha elivamile, isibonelo, livamile uma uvula, kodwa elingavamile ngemva kwesikhashana.Uma kuqhathaniswa nendlela yokushisa, inezinzuzo zokusheshisa, ezilula, ezinembile futhi eziphephile.Isibonelo, i-amplitude yenkundla ye-TV ijwayelekile ngemva kokuvula, kodwa izocindezelwa ngemva kwemizuzu embalwa futhi yakhe i-broadband evundlile ngemva kwesigamu sehora, ishubhu lokukhipha inkambu lizwakala lishisa uma lithintwa ngesandla.Ngalesi sikhathi, faka ibhola lotshwala ku-tube yokukhipha insimu, futhi i-amplitude yasensimini iqala ukuphakama futhi iphutha liyanyamalala maduzane, khona-ke kungahlulelwa ukuthi kubangelwa ukuzinza okushisayo kwe-tube yokukhipha insimu.
15. Indlela yokuhlola umdwebo wenqubo ukuthola indawo enephutha ngokunciphisa ububanzi bephutha isinyathelo ngesinyathelo ngokuya ngomdwebo wenqubo yokulungisa iphutha.
16. Indlela ebanzi ukusebenzisa izindlela ezehlukene ukuhlola amaphutha anzima kakhulu.
