1. Panel compression nzira inoshandisa basa rekuchinja kwega kwega uye knob yakazaruka kunze kwegetsi remagetsi, iyo console kana muchina kuti utarise uye utore kutonga nzvimbo yekukanganisa.Semuyenzaniso, ruzha rweTV rwunoitika pano neapo dzimwe nguva, uye vhoriyamu knob inogadziridzwa kuti ioneke“Kluck”ruzha runoperekedzwa nesporadic ruzha, zvino zvinogona kuzivikanwa kuti vhoriyamu potentiometer haina kusangana kwakashata.
2. Yakananga yekuongorora nzira ndeyekutarisa uye kutonga nzvimbo yekukanganisa nekuona, kubata, kunzwa uye kunhuwa.Iyi nzira inonyanya kukodzera zvikanganiso zvakajeka zvakadai sokupisa, kunhuhwirira kunopisa, kunhuhwirira kweozone uye inzwi risina kunaka.Somuenzaniso, pane a“crack”inonzwika mukati meTV mushure mekuishandura, chifananidzo chinosvetuka nezwi uye kunhuhwirira kwakasimba kwe ozone kunonhuwa, zvino inogona kutongwa kuti mutsara unobuda mushanduri kana chikamu chepamusoro-voltage chiri kupisa.
3. Voltage kuyerwa nzira ndeyekutarisa magetsi ekupa uye voltage yezvikamu zvakakosha kuburikidza nekushandisa multimeter, kunyanya iyo voltage pane zvakakosha.Iyi nzira ndiyo inonyanya kushandiswa uye inowanzoshandiswa yekuongorora nzira yekuchengetedza midziyo yemumba.
4. Nzira yekuyera yemagetsi yemazuva ano ndeyekuyera huwandu hwemazuva ano uye kushanda kwemazuva ano kwe transistors uye zvikamu kuburikidza nekushandiswa kwakakodzera ikozvino yakasiyana-siyana ye multimeter, kuitira kutonga nzvimbo yekukanganisa nokukurumidza.Semuenzaniso, iyo TV inowanzopiswa neDC fuse uye huwandu hwazvino hweyeyero yakadzorwa magetsi yakakura kupfuura kukosha kwakajairika, mutsara wekubuda nhanho wedunhu unodimburwa uye ikozvino inodzokera kune yakajairwa, zvino zvinogona kutariswa kuti iko kukanganisa. iri mumutsara wekubuda nhanho uye matunhu anotevera.
5. Resistance measurement method ndeyekutonga nzvimbo yekukanganisa nekuyera kukosha kwekupikisa kwekupikisa, capacitance, inductance, coil, transistor uye integrated block.
6. Short-circuit nzira inoreva nzira ye AC pfupi-circuit, iyo inonyanya kushanda pakusarudza huwandu hwemhepo ye steamboat, mhere-mhere uye ruzha.Semuenzaniso, kana iwe uchida kutonga kukanganisa kwekuchema kweredhiyo, unogona kushandisa 0.1μF capacitor kupfupi-kutenderera vaunganidzi veiyo inoshandura chubhu, yekutanga yepakati amplification chubhu uye yechipiri yepakati amplification chubhu pasi, zvichiteerana.Kuchema kunopera pane imwe nhanho yedunhu pfupi, kukanganisa kunoitika panguva ino.
7. Circuit disconnecting method ndeyekudzvanya chikanganiso chekukanganisa nekucheka imwe dunhu kana kusunungura chimwe chikamu uye wiring.Semuenzaniso, huwandu hwese hwechishandiso chemagetsi hwakanyanya kukura, chikamu chinofungidzira chedunhu chinogona kubviswa zvishoma nezvishoma.Mhosva inenge iri pachinhanho chekuti ikozvino inodzokera kune yakajairwa kana yadimburwa.Iyi nzira inowanzoshandiswa kugadzirisa kukanganisa kwekunyanyisa ikozvino uye kupisa fuse.
8. Kugogodza nzira ndeyekutonga nzvimbo yekukanganisa kuburikidza nekushandisa diki screwdriver mubato kana sando yehuni kugogodza zvinyoro nyoro imwe nzvimbo pabhodhi redunhu uye tarisa mamiriro acho (Cherechedza: kazhinji hazvisi nyore kugogodza iyo high-voltage chikamu. )Iyi nzira inonyanya kukodzera kutarisa kukanganisa kwenhema welding uye kusabatana kwakashata.Semuenzaniso, hapana ruzha mumufananidzo weTV dzimwe nguva, unogona kugogodza zvinyoro pagoko reTV neruoko rwako, uye kukanganisa kuri pachena.Vhura chivharo chekumashure cheTV, dhonza kunze kwebhodhi redunhu, uye zvinyoro nyoro gogodza zvikamu zvinofungira nescrewdriver handle.Mhosva iri pachikamu ichi apo kukanganisa kunenge kuri pachena kana yagogodzwa.
9. Kutsiva nzira yekuongorora ndeyekutsiva chikamu chinoonekwa sechakashata nekushandiswa kwechikamu chakanaka.Iyi nzira iri nyore uye iri nyore kushandisa, uye kazhinji inekaviri chigumisiro nehafu yekuedza..Inowanzo shandiswa kutsiva tuner, mutsara unobuda transformer, capacitor pazasi 0.1μF, transistor, Integrated block uye zvichingodaro.
.Iyi nzira inowanzoshandiswa kugadzirisa kukanganisa kwakaoma.
11. Kupindira nzira ndeyekutonga kukanganisa nzvimbo nekushandisachikamu chesimbi chescrewdriver uye ma tweezers kubata akakodzera mapoinzi ekuona, tarisa mhinduro ye clutter pachiratidziri uye unzwe“Kluck”kurira kwehwamanda.Iyi nzira inowanzo shandiswa kutarisa chiteshi cheruzhinji, chiteshi chemifananidzo uye chiteshi chenzwi.Semuyenzaniso, hapana mufananidzo kana kurira kukanganisa kunoonekwa, tora screwdriver kuti ubate yekutanga yepakati amplification base.Kana paine clutter mhinduro pachiratidziro uye nyanga ine“Kluck”inzwi, rinoratidza kuti dunhu rakajairika mushure mekusimudzira kwepakati, saka kukanganisa kuri mu tuner kana antenna.
12. Nzira yekuenzanisa ndeyekutsvaga nzvimbo yekukanganisa nekuenzanisa magetsi, waveform uye mamwe maparameter emuchina wakajairwa wemuenzaniso wakafanana nemuchina unokanganisa.Iyi nzira inonyanya kukodzera kana dhiyabhorosi yedunhu isingagoni kuwanikwa.
13. Heating nzira ndeye kukurumidza kutonga nzvimbo yekukanganisa nekupisa iyo inofungidzira chikamu, kuitira kuti ikurumidze“rufu”chechikamu chakadaro.Semuenzaniso, hupamhi hwemutsara hweTV hwakajairika kana ichangobva kubatidzwa, uye upamhi hwemutsara hunodzokororwa maminetsi mashoma gare gare, goko remutsetse wekubuda chubhu inoshanduka yero uye mutsetse unopisa, ipapo unogona kutora solder. simbi kuti iswedere pachubhu yemutsara kuti ipise.Kana hupamhi hwemutsara hunoramba huchidzokera shure, zvinogona kutongwa kuti mutsara wechubhu une chikanganiso.
14. Kutonhora nzira ndeyekukurumidza kutonga nzvimbo yekukanganisa nekutonhodza zvikamu zvinofungira.Iyi nzira inoshandiswa pakukanganisa nguva dzose, semuenzaniso, zvakajairika paunenge uchibatidza, asi zvisiri izvo mushure mechinguva.Kuenzaniswa neiyo nzira yekudziya, ine zvakanakira nekukurumidza, zviri nyore, zvakarurama uye zvakachengeteka.Semuyenzaniso, masimu emumunda eTV akajairika mushure mekubatidza, asi inomanikidzwa mushure memaminitsi mashoma uye inogadzira yakachinjika Broadband mushure mehafu yeawa, iyo munda inobuda chubhu inonzwa inopisa kana yabatwa neruoko.Panguva ino, isa doro bhora pamunda goho chubhu, uye munda amplitude anotanga kusimuka uye kukanganisa anonyangarika nokukurumidza, zvino zvinogona kutongwa kuti kunokonzerwa nokupisa kugadzikana kwemunda goho chubhu.
15. Nzira yekuongorora dhiyabhorosi nzira ndeyekutsvaga nzvimbo yekukanganisa nekudzikisa kukanganisa chiyero nhanho nhanho zvichienderana nedhiyabhorosi yekugadzirisa maitiro.
16. Comprehensive method ndeyekushandisa nzira dzakasiyana-siyana kutarisa zvimwe zvinokanganisa zvakanyanya.
