A. gusana LCD igomba kwiga kumenya igice kitarimo amakosa, iyi niyo ntambwe yambere.Ibikurikira bizavuga ku makosa akomeye n'ibice bigize urubanza rwa LCD.
1: nta shusho nta jwi, itara ryumuriro rimurika mumucyo uhoraho, ecran yaka itara ryera mugihe cyamashanyarazi.Uku kunanirwa ahanini ni inyuma yumushoferi wangiritse.Ariko nanone yahuye mukubungabunga ecran ni kwangirika kw'itara.
2: Nyuma yigihe cyimbaraga kuri ecran (mosaic), amajwi nibisanzwe.Iyi phenomenon niyambere ni ikibaho kibi cya digitale (hejuru yumwobo ntigikora cyangwa guhuza IC ntabwo ari byiza).Iya kabiri ni umubonano mubi muri mashini ihuza.
3: boot eshatu oya, itara ryumuriro ntirimurika.Iya mbere ni ikibaho kibi cyimbaraga, icya kabiri nigice cya CPU cyakazi ntabwo gisanzwe.
4: gucana urumuri ntibishobora gukingurwa: Akazi ka bisi ya CPU ntabwo gasanzwe cyangwa gahunda ya boot ya IC (BIOS) mbi, "BIOS" IC no guhuza nabi hagati ya CPU.
5: ubushyuhe bwo hejuru: tubona imashini murugo rwabakiriya ntabwo irenze urukuta rwometseho urukuta nubwoko bwa pedeste ubwoko bubiri, ariko ibyo nitegereje ku giti cyanjye, icyitegererezo kimwe no kugura igihe kimwe imashini imwe, imashini yubatswe kurukuta kuruta amahirwe yo gutsindwa y'ubwoko bwa pedestal, kandi gutsindwa kimwe nabwo mbere yimyaka 1-2, birasa rero, bifitanye isano nubushyuhe, muriki gihe, nasannye imashini izashyirwaho abafana ba mudasobwa ebyiri kugirango barebe ko igihe cya garanti kitazaba gikwiye ku bushyuhe bwo hejuru hanyuma usubire gusanwa.
6: kurwanya ruswa: usibye inzu y'ibitaramo yavuzwe haruguru, hafi y'imashini yo mu gikoni kurusha izindi mashini zananiranye, kandi ibibazo byabo biva mu kwangirika kw'icyuma hagati y'abahuza, ndetse biganisha ku jisho ry'umuringa rifite impande ebyiri ruswa, inkomoko yibi bintu, byanze bikunze, ikibazo cyubwiza bwikirere, kugirango iki kibazo gikosorwe, nkoresha uburyo bwo gufunga amavuta ya silicone yubushyuhe kandi ntibigira ingaruka kubushuhe, byanze bikunze, abahuza Icyuma kigomba gukoreshwa na reberi kugirango gisukure.
7: Hafi ya ecran yose izagaragara kumurongo wumukara, ikibazo cyumurongo ugaragara, gusana aya makosa mbere kugirango ugire ibyangombwa byo gusana, nyuma yo kurangiza gusana gerageza gukoresha amavuta yumuriro yashizwemo amanota menshi muri moderi ya COF IC kuko iki kibazo nacyo cyatewe n'ubushyuhe.
LCD TV ikunze kunanirwa hamwe nuburyo bwo gusana (LCD TV icumi byananiranye)
Icya kabiri, imashini isanzwe nibibazo hamwe nuburyo bwo gukemura ibibazo
1: Nkuko byavuzwe haruguru, ikibazo cya ecran (umurongo wumukara, umurongo ugaragara) nicyo kinini, iki kibazo muri rusange mugihe hatabayeho uburyo bwo kubungabunga ntibishobora gukora, gusa bishingiye kubuhanga no kubungabunga ibidukikije.
: no kugura abantu babiri ntibazakugurisha numwe) cyangwa gupima igice cya IC kibi, gusimbuza bishobora kuba.
3: Ntakibazo cyaba ecran, Y ikibaho kiri mumashini ya PDP imbere mumahirwe yo kubarwa kubwa kabiri, muri rusange byangiritse nyuma yuko phenomenon ari ecran, yuzuye utudomo twamabara, cyangwa kubera imiyoboro migufi no kurinda ingufu, VS cyangwa VA voltage ako kanya, ariko ntabwo igera kuri ecran ya voltage agaciro kumeza yihariye impamvu byoroshye kubibi, sinzi impamvu.
4: X ikibaho nacyo ni imashini ya PDP akenshi ibice bibi, imikorere yayo yo kurinda boot (ecran ya Fujitsu ahanini), numucyo wijimye.
5. nibindi bimwe ntibishobora gufungura.
6. ingingo ya ACF ivuye muriki kintu irashobora gusanwa hamwe nicyuma kiringaniye munsi ya pad insulation media uburyo bushyushye
7: Imashini ya LCD, ibice bigize ecran ya inverter umuzenguruko (ikibaho kinini cya voltage) ni ibice bikunze kwibeshya, bigaragazwa nkumucyo, ariko mugihe gito ntamucyo, ariko hariho amajwi, (usibye SHARP), ariko umuyoboro wumucyo usaza no kwangirika bizaganisha ku kurinda amashanyarazi menshi, kugirango hamenyekane niba umuyoboro woroheje cyangwa ikibaho kinini cya voltage ubwacyo ari kibi, kurandura ikibaho kinini cya voltage ku gipimo mpuzandengo cy’ibitekerezo byagereranijwe.
8. ibice by'amakosa.
Icya gatatu, LCD TV yerekana urumuri rusanzwe
1. itara ryinyuma muri AC power-on ako kanya LCD ya ecran ya ecran gato, muriki gihe, amajwi aherekejwe, kugenzura kure, imikorere ya buto yo kugenzura ni ibisanzwe Iki kintu giterwa no kurinda urumuri rwinyuma, impamvu yo kuzamura urumuri rwinyuma amashanyarazi yamashanyarazi adasanzwe kumatara yinyuma ya CCFL, niba umuyoboro winyuma ufunguye uruziga (rusanzwe kumatara yinyuma yamatara yamatara ya sock yafunguye kugurisha cyangwa sock ntabwo yashyizwemo cyane biterwa no kurinda umuzunguruko) cyangwa itara ryacitse rishobora gutera kunanirwa hejuru.
2. itara ryinyuma ntihinduka, hamwe nijwi, kugenzura kure, kugenzura buto nibisanzwe iri kosa rikeneye kumenya imiterere yakazi ikurikira.
(1).urumuri rwinyuma rwumuzunguruko rutanga amashanyarazi, rusanzwe rusanzwe kuri 24 volt, bike cyane hamwe na volt 120, ecran ntoya muri rusange volt 12.
(2).CPU igenzura imizunguruko isohoka inyuma yamashanyarazi yamashanyarazi oscillator akazi ko guhinduranya ibimenyetso, bisanzwe murwego rwohejuru rwo gutangira, ibimenyetso byinshi byo kugenzura itara rya 3V-5V niba ibimenyetso byakazi byavuzwe haruguru birahari, noneho urashobora gusimbuza ikibaho cyamatara yinyuma, niba gusimbuza urumuri rwinyuma kunanirwa kw'ibibaho nko mu ntangiriro, ahanini kubice bya LCD mugice cyinyuma cyangiritse.
3. iyo itara ryinyuma rimurika kandi ntirimurika, birasanzwe ko itara ryamatara ryurubaho rwinyuma rufite itumanaho ridafite itara, kandi amashanyarazi yinyuma ni menshi cyangwa make.
