A. los kho lub LCD yuav tsum kawm los txiav txim seb qhov twg yog qhov txhaum, qhov no yog thawj kauj ruam. Cov hauv qab no yuav tham txog qhov ua txhaum loj thiab qhov chaw ntawm LCD TV kev txiav txim.
1: Tsis muaj duab tsis muaj suab, lub teeb lub zog flashes rau hauv lub teeb tas li, lub vijtsam flashes lub teeb dawb thaum lub sijhawm fais fab. Qhov kev ua tsis tiav no feem ntau yog backlight tsav tsheb puas. Tab sis kuj tau ntsib nyob rau hauv kev saib xyuas ntawm qhov screen yog lub teeb puas.
2: Tom qab lub sijhawm ntawm lub zog ntawm lub vijtsam (mosaic), lub suab zoo li qub. Qhov tshwm sim no yog thawj zaug yog lub rooj tsav xwm digital tsis zoo (dhau lub qhov tsis ua haujlwm lossis IC kev sib cuag tsis zoo). Qhov thib ob yog kev sib cuag tsis zoo nyob rau hauv lub tshuab kev sib txuas.
3: khau raj peb tsis, lub hwj chim teeb tsis teeb. Thawj yog lub rooj tsav xwm tsis zoo, qhov thib ob yog CPU feem ntawm kev ua haujlwm tsis zoo li qub.
4: Lub teeb flashing tsis tuaj yeem qhib: CPU tsheb npav ua haujlwm tsis zoo lossis khau raj IC (BIOS) phem, "BIOS" IC thiab kev sib cuag tsis zoo ntawm CPU.
5: qhov kub thiab txias: peb pom lub tshuab hauv cov neeg siv khoom lub tsev tsis muaj ntau tshaj li phab ntsa-mounted thiab pedestal hom ob qhov chaw, tab sis kuv tus kheej kev soj ntsuam, tib lub qauv thiab yuav lub sij hawm tib lub tshuab, phab ntsa-mounted tshuab tshaj lub sij hawm ntawm tsis ua hauj lwm ntawm lub pedestal hom, thiab tib yam tsis ua hauj lwm thaum ntxov 1-2 xyoo, yog li nws zoo nkaus li, muaj feem xyuam rau qhov kub thiab txias, nyob rau hauv cov ntaub ntawv no, lub computer yuav tsis tau kho ob lub sij hawm rau cov kiv cua. Kub kub thiab rov qab kho.
6: corrosion resistance: ntxiv rau cov lus hais saum toj no, nyob ze ntawm lub tshuab chav ua noj dua li lwm lub tshuab tsis ua haujlwm, thiab lawv cov teeb meem yog los ntawm corrosion ntawm cov hlau nto ntawm cov khoom sib txuas, thiab txawm ua rau ob sab tooj liab qhov muag corrosion, qhov chaw ntawm qhov tshwm sim yog, ntawm chav kawm, qhov teeb meem ntawm huab cua zoo, rau kev kho qhov teeb meem no, Kuv siv cov txheej txheem ntawm kev sib khi ntawm cov khoom siv hluav taws xob tsis zoo rau cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob. chav kawm, cov khoom sib txuas Cov hlau yuav tsum tau siv nrog roj hmab los thov kom huv.
7: Yuav luag txhua qhov screen yuav tshwm dub band, teeb meem kab teeb, kho qhov txhaum ua ntej kom muaj kev kho, tom qab ua tiav kev kho sim siv cov roj thermal coated nrog ntau cov ntsiab lus hauv COF module IC vim qhov teeb meem no kuj tshwm sim los ntawm qhov kub thiab txias.
LCD TV ntau yam tsis ua haujlwm thiab kho txoj hauv kev (LCD TV kaum qhov ua tsis tiav)
Qhov thib ob, lub tshuab ua haujlwm thiab qhov tshwm sim txhaum cai thiab kev daws teeb meem
1: Raws li tau hais los saum toj no, qhov teeb meem ntawm qhov screen (dub band, ci kab) yog qhov feem ntau, qhov xwm txheej no feem ntau yog qhov tsis muaj kev saib xyuas tsis tuaj yeem ua, tsuas yog tso siab rau cov cuab yeej siv thiab kev saib xyuas.
2: LG screen Cheebtsam ntawm lub rooj tsavxwm tsis yog feem ntau qhov tsis zoo ntawm qhov tshwm sim yog tag nrho ntawm kev tshuaj ntsuam lwm cov ntsiab lus, tab sis kuj muaj qee qhov muaj cov kab ntsug ntsug tsis tu ncua, qhov tsis ua haujlwm no tuaj yeem hloov tau ib khub ntawm lub rooj tsavxwm tsis zoo (txawm tias yog ib qho tsis zoo, tab sis kuj yuav ib khub ntawm tib neeg yuav tsis muag ib leeg rau koj) lossis ntsuas seb daim IC phem, hloov nws li cas.
3: Txawm tias lub vijtsam twg, Y board yog nyob rau hauv lub tshuab PDP hauv qhov muaj feem cuam tshuam tsis zoo rau qhov thib ob, feem ntau puas tom qab qhov tshwm sim yog qhov screen, tag nrho cov xim dots, los yog vim luv luv Circuit Court thiab lub zog tiv thaiv, VS los yog VA voltage tam sim ntawd, tab sis tsis mus txog qhov screen voltage tus nqi ntawm lub rooj tshwj xeeb yog vim li cas yooj yim rau phem, kuv tsis paub yog vim li cas.
4: X pawg thawj coj kuj tseem yog lub tshuab PDP feem ntau cov khoom tsis zoo, nws qhov kev ua tau zoo rau kev tiv thaiv khau raj (Fujitsu screen feem ntau), thiab ci ntsa iab.
5: Qhov tsis ua hauj lwm ntawm lub rooj tsav xwm logic tsis qis, hauv PDPLCD muaj ntau dua, nws qhov kev ua haujlwm feem ntau yog lub teeb pom kev zoo, tab sis yuav tsis muaj cov cim, tsis muaj duab, lossis cov duab irregularities chaotic xim, tsis muaj xim, duab tsis zoo, thiab lwm yam. Qee qhov tsis tuaj yeem tig rau.
6: LCD ntau qhov ua tsis tau zoo yog cov teeb meem tshuaj ntsuam, cov kab tsaus nti, kab, yog qhov tshwm sim ntau tshaj plaws, cov ntsiab lus no tuaj yeem ua tiav raws li cov teeb meem tshuaj ntsuam, qee qhov yuav tsum muaj kev kho kom zoo, qee qhov vim qhov kub thiab txias, uas ua rau COF thiab qhov screen txuas ntawm ACF tawm ntawm qhov tshwm sim no tuaj yeem kho nrog lub tiaj tiaj hauv qab lub ncoo rwb thaiv tsev xov xwm kub txoj kev.
7: LCD tshuab, lub vijtsam tivthaiv inverter Circuit Court (high-voltage board) yog qhov txhaum-nrawm, tshwm sim raws li lub teeb rau, tab sis ib pliag tsis muaj lub teeb, tab sis muaj suab, (tshwj tsis yog SHARP), tab sis lub teeb lub teeb aging thiab kev puas tsuaj yuav ua rau high-voltage board tiv thaiv, los txiav txim seb lub teeb lub teeb los yog high-voltage lub rooj tsavxwm yog qhov nruab nrab ntawm qhov tsis zoo ntawm lub rooj tsavxwm. kev sib piv cov lus qhia Circuit Court.
8: Ntau tus phooj ywg nug yuav ua li cas tswj lub SHARP LCD, qhov tseeb, thiab cov LCD zoo ib yam li nkag mus rau hauv cov ntawv qhia zaub mov, koj tuaj yeem pom cov khoom yuam kev muaj cov lej txhaum cai, qee qhov ncaj qha rau tus lej xoom, qee qhov yuav tsum tau kho qhov sib thooj ntawm qhov txhaum.
Thib peb, LCD TV backlight kev txiav txim txhaum cai
1. lub backlight nyob rau hauv AC lub hwj chim-on instant LCD npo lub teeb tawm me ntsis, lub sij hawm no, lub suab nrog, tej thaj chaw deb tswj, vaj huam sib luag khawm tswj lub luag hauj lwm no tshwm sim los ntawm backlight Circuit Court tiv thaiv, vim li cas rau lub backlight booster board fais fab mov txawv txav rau CCFL backlight Circuit Court, yog ib tug backlight raj qhib Circuit Court (ntau tshaj rau lub backlight boards muag ntxig nruj nreem los ntawm kev tiv thaiv Circuit Court) lossis Lub teeb tawg tuaj yeem ua rau qhov tsis ua haujlwm saum toj no.
2. lub backlight hloov tsis hloov, nrog lub suab, cov chaw taws teeb tswj, vaj huam sib luag khawm tswj yog ib txwm ua txhaum no yuav tsum tau kuaj xyuas cov haujlwm hauv qab no.
(1). lub backlight booster circuit fais fab mov, ib qho screen loj rau 24 volts, tsawg heev nrog 120 volts, me me screen feem ntau yog 12 volts.
(2). CPU tswj Circuit Court output backlight booster board oscillator ua hauj lwm hloov tswj teeb liab, feem ntau rau theem siab pib, ntau 3V-5V teeb teeb pom kev zoo tswj teeb liab yog hais tias cov saum toj no ua hauj lwm tej yam kev mob muaj, ces koj muaj peev xwm hloov lub backlight booster board, yog hais tias lub hloov backlight booster board tsis ua hauj lwm raws li thaum pib, feem ntau yog rau lub LCD screen Cheebtsam nyob rau hauv lub backlight raj puas.
3. Thaum lub teeb ci ntsa iab thiab tsis ci, nws yog ib qho uas lub teeb lub qhov hluav taws xob ntawm lub backlight booster board muaj kev sib cuag tsis zoo nrog lub teeb, thiab lub backlight fais fab mov yog siab lossis qis.
