Ni ibihe bintu bikunze kugorana kuri televiziyo ya LCD?

A. Gusana LCD bigomba kwiga kumenya igice gifite ikibazo, iyi ni intambwe ya mbere. Ibikurikira bizavuga ku makosa y'ingenzi n'ibice by'isuzuma rya televiziyo ya LCD.

1: nta shusho nta rusaku, urumuri rw'amashanyarazi rurashya rukavamo urumuri ruhoraho, ecran ikamura urumuri rwera mu gihe cyo kuyicana. Uku gucika intege ahanini ni ukwangirika kw'ikibaho cy'umushoferi w'inyuma. Ariko nanone mu kubungabunga ecran ni ukwangirika kw'itara.

2: Nyuma y'igihe cy'ingufu kuri ecran (mosaic), ijwi riba risanzwe. Iki kintu cya mbere ni ikibaho kibi cya digitale (hejuru y'umwobo ntigikora cyangwa aho uhurira na IC ntabwo ari heza). Icya kabiri ni aho uhurira na mashini.

3: boot ya gatatu oya, itara ry'amashanyarazi ntirika. Iya mbere ni power board mbi, iya kabiri ni uko CPU igice cy'akazi atari gisanzwe.

4: urumuri ntirushobora gufunguka: Umurimo wa bisi ya CPU ntabwo usanzwe cyangwa porogaramu ya boot IC (BIOS) mbi, "BIOS" IC n'imikoranire mibi hagati ya CPU.

5: ubushyuhe bwinshi: tubona ko imashini iri mu rugo rw'umukiriya nta kindi uretse gushyiramo imashini ku rukuta no gushyiramo imashini ku bwoko bwa kabiri, ariko ubwanjye niboneye ko imashini imwe n'igihe cyo kuyigura, imashini ishyirwa ku rukuta ari amahirwe yo kwangirika kw'imashini, kandi ko byangiritse mu ntangiriro z'umwaka 1-2, nk'uko bigaragara, bifitanye isano n'ubushyuhe, muri iki gihe, nasananye imashini izashyiraho amafeni abiri ya mudasobwa kugira ngo garanti itazaba iterwa n'ubushyuhe bwinshi no gusubira gusanwa.

6: kurwanya ingese: uretse icyumba cy'ibitaramo cyavuzwe haruguru, hafi y'imashini yo mu gikoni kurusha izindi mashini zinanirwa gukora neza, kandi ibibazo byazo bikomoka ku ingese y'ubuso bw'icyuma hagati y'ibihuza, ndetse bigatera ingese y'amaso y'umuringa ifite impande ebyiri, inkomoko y'iki kibazo, birumvikana, ni ikibazo cy'ubuziranenge bw'umwuka, kugira ngo iki kibazo gikemuke, nkoresha uburyo bwo gufunga n'amavuta ya silicone atwara ubushyuhe kandi ntibigira ingaruka ku gushonga k'ubushyuhe, birumvikana ko ibihuza icyuma bigomba gusigwa na rubber kugira ngo gikoreshwe neza.

7: Hafi ya ecran yose izagaragaramo umugozi w'umukara, ikibazo cy'umurongo w'urumuri, banza usane iki kibazo kugira ngo gikosorwe, nyuma yo gusana gerageza gukoresha amavuta y'ubushyuhe atwikiriwe n'ingingo nyinshi muri module ya COF IC kuko iki kibazo giterwa n'ubushyuhe.

Uburyo bwo gusana amakosa asanzwe ya televiziyo ya LCD (amakosa icumi asanzwe ya televiziyo ya LCD)

Icya kabiri, uburyo busanzwe bwo gukemura ibibazo by'imashini n'amakosa n'uburyo bwo gukemura ibibazo

1: Nkuko byavuzwe haruguru, ikibazo cya ecran (umukara, umurongo ugaragara) ni cyo gikomeye kurusha ibindi, muri rusange iyo nta miterere y’ibikorwa byo kubungabunga ishobora gukorwa, ishingiye gusa ku ikoranabuhanga n’imiterere y’ibikorwa byo kubungabunga.

2: Ibice bya ecran ya LG bya ecran ya buffer akenshi ni bibi ibice by'ibyabaye byuzuyemo ingingo zitandukanye za ecran, ariko nanone bimwe byuzuyemo imirongo ihagaze neza, uku gutsindwa gushobora gusimbura ecran ya buffer (nubwo byaba ari bibi, ariko no kugura ecran y'abantu ntabwo bizakugurisha kimwe) cyangwa gupima igice cya IC kibi, kugisimbuza gishobora kuba kibi.

3: Uko ecran ya Y yaba iri kose, board ya PDP ishobora kuba mbi, muri rusange yangiritse nyuma y’uko ecran ibaye, yuzuyemo utudomo tw’amabara, cyangwa bitewe n’uburinzi bw’amashanyarazi n’ingufu, VS cyangwa VA voltage ako kanya, ariko ntabwo igera ku gaciro ka ecran voltage y’imbonerahamwe, impamvu yoroshye kuyiba nabi, sinzi impamvu.

4: X board nayo ni imashini ya PDP ikunze kuba mbi, imikorere yayo mu kurinda boot (ecran ya Fujitsu ahanini), kandi urumuri rwijimye.

5: Igipimo cyo gutsindwa kwa logique board ntabwo kiri hasi, muri PDPLCD ni byinshi, imikorere yayo ahanini ni urumuri rwa ecran, ariko nta nyuguti zizaba zihari, nta shusho, cyangwa amakosa y'ishusho azabaho, nta ibara rihari, ishusho mbi, nibindi. Bimwe ntibishobora gufungurwa.

6: Ibibazo bikunze kugaragara kuri LCD ni ibibazo bya ecran, imigozi yijimye, imirongo, ni byo bikunze kugaragara cyane, ibi bibazo by'ibanze bishobora gusobanurwa nk'ibibazo bya ecran, bimwe bifite imiterere yo gusana, bimwe bitewe n'ubushyuhe bwinshi, bigatuma COF n'aho ecran ihurira na ACF muri iki kibazo bishobora gusanwa hakoreshejwe icyuma gifunganye munsi y'icyuma gishyushya. Uburyo bwo gushyushya bukoreshwa mu gushyushya ecran.

7: Imashini ya LCD, uruziga rw'ibikoresho bya ecran (ikibaho gifite voltage nyinshi) ni ibice bishobora kugira amakosa, bigaragara nk'urumuri rwaka, ariko igihe gito nta rumuri, ariko hari urusaku, (usibye SHARP), ariko umuyoboro w'urumuri ushaje kandi ukangirika bizatuma ikibaho gifite voltage nyinshi kirindwa, kugira ngo hamenyekane niba umuyoboro w'urumuri cyangwa ikibaho gifite voltage nyinshi ubwacyo ari bibi, gukuraho ikibaho gifite voltage nyinshi ku gaciro mpuzandengo k'uruziga rw'ibitekerezo bigereranywa.

8: Inshuti nyinshi zibaza uburyo bwo kubungabunga SHARP LCD, mu by'ukuri, na LCD isanzwe isa n'aho yinjira muri menu yo kubungabunga, ushobora kubona ibintu by'amakosa hari kode z'amakosa, zimwe kuri kode zeru, izindi zigomba gusana ibice bihuye n'ikosa.

Icya gatatu, uburyo bwo gusuzuma amakosa asanzwe ya televiziyo ya LCD

1. Itara ry'inyuma muri ecran ya LCD ihita ikoresha AC rizimye gato, muri iki gihe, ijwi rijyana naryo, uburyo bwo kugenzura kure, n'imikorere y'utubuto tw'aho bihurira ni ibisanzwe. Iki kintu giterwa no kurinda uruziga rw'urumuri, impamvu y'amashanyarazi y'urumuri rw'inyuma adasanzwe kuri CCFL backlight circuit, niba uruziga rw'urumuri rw'inyuma (rusanzwe kuri backlight booster board light socket open solder cyangwa socket idashyizwemo neza bitewe n'uburinzi bw'urumuri) cyangwa Itara ryangiritse rishobora gutera ikibazo cyavuzwe haruguru.

2. Nta gihindutse cy'urumuri rw'inyuma, hamwe n'amajwi, remote control, na panel control ni ibisanzwe, iki kibazo kigomba kugaragara kugira ngo hamenyekane imikorere ikurikira.

(1). Ingufu z'amashanyarazi zo kongera urumuri rw'inyuma, ecran nini isanzwe ya volts 24, nke cyane ifite volts 120, ecran nto muri rusange ni volts 12.

(2). ikimenyetso cyo kugenzura uruziga rw'amashanyarazi rwa CPU, ikimenyetso cyo kugenzura imikorere y'urumuri rw'inyuma, gisanzwe cyo gutangiza ku rwego rwo hejuru, ikimenyetso cyo kugenzura amatara ya 3V-5V niba imiterere y'akazi yavuzwe haruguru ihari, ushobora gusimbuza uruziga rw'inyuma, niba uruziga rw'inyuma rusimbura rwarangiritse nk'uko byari bimeze mu ntangiriro, ahanini ku bice bya ecran ya LCD mu muyoboro w'inyuma byangiritse.

3. Iyo itara ry'inyuma ricanye kandi ritari ricanye, ni ibisanzwe ko aho itara ricana haba hari aho rihurira nabi n'itara, kandi umuriro w'itara ry'inyuma uba uri hejuru cyangwa hasi.
