Kev txiav txim ntawm cov teeb meem tshwm sim ntawm LCD:
1. Tag nrho cov saib tsis muaj lub hwj chim tsis ua hauj lwm: kev tsom xam ntawm qhov tsis ua hauj lwm no yog qhov yooj yim. Rau cov ntxaij vab tshaus LCD, feem ntau muaj ob lub zog, sab hauv thiab sab nraud. Cov khoom siv hluav taws xob sab nraud yog ntau dua. Tab sis tsis muaj teeb meem dab tsi ntawm cov khoom siv hluav taws xob, nws cov qauv yooj yim dua li ntawm CRT saib. Feem ntau, cov khoom me me tau yooj yim puas. Muab ob peb piv txwv, xws li fuse, input inductor, Zener diode, lossis hloov raj.
2. Nyob rau hauv lub LCD npo kho, lub motherboard cpu ua rau lub tsis ua hauj lwm, xws li lub hwj chim yuav pib tsis tau, thiab lwm yam. Los ntawm qhov pom ntawm txoj cai, qhov no kuj tseem yooj yim nyob rau hauv txoj cai. Feem ntau, lub rooj tsavxwm tseem ceeb yog siv los txuas rau cpu, thiab tom qab ntawd lub cpu tso tawm cov teeb liab tswj kom tsav lub zog hluav taws xob los hloov cov kev sib txuas ua haujlwm.
3. Lub vijtsam zaub hloov xim dub thaum nws teeb, tab sis lub teeb pom kev muaj feem cuam tshuam ib txwm nyob. Ib qho xwm txheej zoo li no yog qhov kev txiav txim ntawm kev tiv thaiv Circuit Court tshwm sim los ntawm qhov tsis zoo ntawm high-voltage abnormality. Hauv qhov xwm txheej no, yuav muaj cov zaub ntawm LCD npo, uas tuaj yeem pom los ntawm squinting. Kuj tseem muaj cov ntsiab lus tseem ceeb rau kev kho, uas yog sib piv txoj kev kho. Tam sim no, peb cov LCD vaj huam sib luag high-voltage board tsim yog symmetrical, thiab nws yog tsis yooj yim sua rau ob sab yuav tawg. Tsis tas li ntawd, lub tshuab qub muaj teeb meem nrog cov kauj ruam-up transformer lossis lub teeb lub raj, thaum lub tshuab tshiab muaj ntau yam teeb meem hauv kev tiv thaiv Circuit Court thiab txheej txheem.
4. Muaj teeb meem ntawm cov kab ci ntsa iab lossis tsaus nti ntawm qhov screen, uas feem ntau yog teeb meem nrog lub vijtsam LCD. Txoj kab ci tsis ua haujlwm yog tshwm sim los ntawm qhov teeb meem ntawm kev sib txuas ntawm cable rau LCD npo. Txoj kab tsaus nti yog tshwm sim los ntawm qhov xau ntawm qhov screen nws tus kheej. Nws tuaj yeem hais tias ob qhov xwm txheej saum toj no yeej tsis muaj nqi kho. Tus nqi ntawm kev hloov lub vijtsam tuaj yeem yog tib yam li kev yuav ib lub tshiab.
5. Frozen los yog dawb screen tshwm, uas yog tshwm sim los ntawm ib tug teeb meem ntawm lub screen tsav voltage. Tab sis yog hais tias qhov screen tsav Circuit Court nyob rau hauv lub motherboard, yog vim li cas rau lub motherboard. Yog hais tias lub voj voog tsav nyob rau ntawm lub vijtsam LCD, lub vijtsam hloov pauv vim muaj kev pheej hmoo siab ntawm kev saib xyuas.
6. Lub vijtsam muaj xim tsis ua haujlwm. Qhov no tuaj yeem hloov kho raws li los ntawm kev saib xyuas kev hloov kho.
