A. kugadzirisa LCD inofanira kudzidza kuona kuti ndeipi chikamu chakashata, iyi ndiyo nhanho yekutanga.Izvi zvinotevera zvichataura pamusoro pekukanganisa kukuru uye zvikamu zveLCD TV kutonga.
1: hapana mufananidzo hapana ruzha, mwenje wemagetsi unopenya muchiedza chinogara chiripo, skrini inopenya mwenje chena panguva yekubatidzwa kwesimba.Kutadza uku kunonyanya kukuvadzwa kwebacklight driver board.Asi zvakare yakasangana mukugadziriswa kwechidzitiro ndiko kukuvara kwemwenje.
2: Mushure menguva yesimba pachiratidziro (mosaic), ruzha rwakajairika.Ichi chiitiko chekutanga idhijitari bhodhi rakashata (pamusoro pegomba harishande kana IC kuonana hakuna kunaka).Yechipiri ibatanidzo yakaipa mukati mekubatana kwemuchina.
3: bhutsu matatu kwete, mwenje wemagetsi hauvheneke.Yekutanga ibhodhi rakashata remagetsi, yechipiri ndiyo chikamu cheCPU chebasa hachina kujairika.
4: mwenje unopenya haugone kuvhurwa: CPU bhazi basa harina kujairika kana bhutsu chirongwa IC (BIOS) yakaipa, "BIOS" IC uye kusabatana kwakashata pakati peCPU.
5: tembiricha yakakwira: tinoona muchina uri mumba memutengi hausi wekupfuura madziro-akaiswa uye pedestal mhando mbiri yekuisa, asi yangu yekutarisa, yakafanana modhi uye kutenga nguva muchina mumwechete, muchina wakaiswa pamadziro pane mukana wekukundikana. yemhando yepedestal, uye kukundikana kwakafanana zvakare kutanga kwe 1-2 makore, saka zvinoita sekunge, kune chekuita nekushisa, mune iyi kesi, ini ndakagadzirisa muchina uchaiswa mafeni maviri emakombuta kuti ave nechokwadi chekuti nguva yewaranti haizovipo. kune High tembiricha uye kudzokera kugadzirisa.
6: corrosion resistance: kuwedzera kuhoro yekonsati yataurwa pamusoro apa, padhuze nemuchina wekubikira pane kumwe kutadza kwemichina, uye matambudziko avo anotorwa kubva mukuora kwesimbi yepasi pakati pezvibatanidza, uye inototungamira kune kaviri-mativi ziso rendarira. ngura, kunobva chiitiko ichi, hongu, dambudziko remhando yemhepo, pakugadzirisa mamiriro ezvinhu aya, ndinoshandisa nzira yekuisa chisimbiso ne-heat-conductive silicone grease uye haikanganisi kupisa kupisa, hongu, zvibatanidza. Iyo simbi inofanira kuiswa nerabha kuti ishandise yakachena.
7: Inenge yese skrini ichaonekwa bhendi dema, dambudziko remutsara wakajeka, gadzirisa chikanganiso ichi kutanga kuve nemamiriro ekugadzirisa, mushure mekupedzwa kwekugadzirisa edza kushandisa girisi inopisa yakavharwa nemamwe mapoinzi muCOF module IC nekuti dambudziko iri rinokonzereswa. nekupisa.
LCD TV yakajairika kutadza uye kugadzirisa nzira (LCD TV gumi zvakajairika kutadza)
Chechipiri, iyo yakajairika muchina uye kukanganisa chiitiko uye nzira dzekugadzirisa matambudziko
1: Sezvataurwa pamusoro apa, dambudziko rekrini (black bhendi, mutsara wakajeka) ndiyo yakanyanya, mamiriro ezvinhu aya anowanzo kushayikwa kwemamiriro ekugadzirisa haagone kuita, kungovimba nehunyanzvi uye mamiriro ekugadzirisa.
2: LG skrini yezvikamu zvebuffer board inowanzova yakaipa zvikamu zvechiitiko izere nescreen zvakasiyana mapoinzi, asi zvakare mamwe azere neanogara akamira mbariro, kutadza uku kunogona kutsiva peya yebuffer board (kunyangwe kana yakashata, asi zvakare kutenga vanhu vaviri hakutengesi imwe kwauri) kana kuyera kuti ndeipi chidimbu cheIC chakashata, chinja chinogona kuva.
3: Hazvina mhosva kuti ndechipi chidzitiro, Y bhodhi iri mumushini wePDP mukati memikana yekuipa yakaverengerwa yechipiri, inowanzokuvadzwa mushure mekunge chiitiko chiri chidzitiro, chizere nemavara emavara, kana nekuda kwepfupi dunhu nekudzivirira simba, VS. kana VA voltage ipapo, asi kwete kusvika pachiratidziro voltage kukosha kwetafura chaiyo nei zviri nyore kuipa, ini handizive chikonzero.
4: X bhodhi zvakare PDP muchina kazhinji yakaipa zvikamu, kuita kwayo kwekudzivirira kwebhutsu (Fujitsu skrini kazhinji), uye kupenya kwakasviba.
5: Chiyero chekutadza kweiyo logic board hachina kuderera, muPDPLCD yakajairika, kuita kwayo kunonyanya kuvhenekera skrini, asi hapazove nevatambi, hapana mufananidzo, kana mufananidzo zvisirizvo chaotic ruvara, kushaya ruvara, chimiro chisina kunaka, etc. Zvimwe hazvibatike.
6: LCD zvakanyanya kutadza kutadza zvidzitiro, mabhandi erima, mitsara, ndiyo yakanyanya kuwanda, izvi zvakakosha zvinogona kupfupikiswa sezvinetso zvekrini, vamwe kuve nekugadzirisa mamiriro ekugadzirisa, vamwe nekuda kwekupisa kwakanyanya, zvichikonzera COF uye skrini yekubatanidza. poindi yeACF kunze kwechiitiko ichi inogona kugadziriswa nesimbi yakatsetseka pazasi pe pad insulation media inopisa nzira.
7: LCD muchina, chidzitiro chinopinda inverter redunhu (yakakwirira-voltage bhodhi) inokanganisa-inotapukira zvikamu, inoratidzwa sechiedza pa, asi kwechinguva pasina mwenje, asi pane ruzha, (kunze kweSHARP), asi mwenje chubhu kuchembera. uye kukanganisa kuchaita kuti pave ne-high-voltage board protection, kuti uone kana iyo chiedza chubhu kana bhodhi yepamusoro-voltage pachayo yakaipa, kubviswa kwe-high-voltage board paavhareji kukosha kwekuenzanisa mhinduro yedunhu.
8: Shamwari zhinji dzinobvunza nzira yekuchengetedza iyo SHARP LCD, chokwadi, uye yakajairwa LCD yakafanana nekupinda mugadziriso menyu, unogona kuona kukanganisa kwezvinhu kune zvikanganiso makodhi, mamwe akananga kukodhi zero, vamwe vanofanirwa kugadzirisa zvinoenderana. zvikamu zvekukanganisa.
Chechitatu, iyo LCD TV backlight yakajairika kukanganisa kutonga
1. the backlight in the AC power-on instant LCD screen light zvishoma, panguva ino, the anoperekedza inzwi, remote control, panel bhatani control mabasa zviri normal Ichi chiitiko chinokonzerwa ne backlight circuit protection, chikonzero che backlight booster. bhodhi magetsi ekupa abnormal yeCCFL backlight circuit, kana backlight chubhu yakavhurika redunhu (yakajairika kune backlight booster board rambi socket yakavhurika solder kana socket haina kuiswa zvakasimba zvichikonzerwa nekuchengetedzwa kwedunhu) kana Rambi rakaputsika rinogona kukonzera kutadza kuri pamusoro.
2. the backlight switch hapana shanduko, ine ruzha, remote control, panel bhatani control zvakajairika mhosva iyi inoda kuona zvinotevera kushanda mamiriro.
(1).iyo backlight booster circuit power supply, yakajairika hombe chidzitiro che 24 volts, shoma kwazvo ine 120 volts, diki skrini inowanzoita gumi nemaviri volts.
(2).iyo CPU inodzora redunhu inoburitsa backlight booster board oscillator basa switch yekudzora siginecha, yakajairika padanho rekutanga, yakawanda 3V-5V mwenje yekudzora chiratidzo kana mamiriro ekushanda ari pamusoro aripo, saka unogona kutsiva backlight booster board, kana inotsiva backlight booster. bhodhi kukundikana sepakutanga, kunyanya kune iyo LCD skrini zvikamu mu backlight chubhu kukuvara.
3. apo chiedza chemashure chiri kupenya uye chisina kujeka, zvinowanzoitika kuti chigadziko chemwenje chebhoti chebheti chebheti chine hukama husina kunaka nemwenje, uye magetsi emagetsi emagetsi akakwirira kana akaderera.
