1. Emeza ikibazo cy'ikosa
Reba uko byagenda nyuma yuko ecran ifunguye (urugero niba urumuri rw'inyuma rwarabagirana, niba hari ibirimo kwerekana, ijwi ridasanzwe, nibindi).
Reba niba ecran ya LCD ifite ibyangiritse ku mubiri (imiturire, amazi ava mu mazi, ibimenyetso byo gushya, nibindi).
2. Emeza neza amashanyarazi yinjira
Pima voltage yinjiye: Koresha multimeter kugira ngo umenye niba voltage nyayo yinjiye ihamye kuri 12V.
Iyo voltage iri hejuru cyane ya 12V (nk'iyo hejuru ya 15V), ishobora kwangirika bitewe n'ingufu nyinshi.
Reba niba adaptateri y'amashanyarazi cyangwa igikoresho gitanga umuriro bidakora neza.
Reba polarity y'amashanyarazi: Emeza niba inkingi nziza n'imbi z'aho umuriro uhurira zihujwe inyuma (guhuza inyuma bishobora gutuma umuriro ugabanuka cyangwa gushya).
3. Kugenzura imiyoboro y'imbere
Igenzura ry'ikibaho cy'amashanyarazi:
Reba niba hari ibice byahiye ku kibaho cy'amashanyarazi (nk'ubwinshi bwa capacitor, gutwika chip ya IC, fuse yahiye).
Genzura niba ingufu zisohoka z'ikibaho cy'amashanyarazi (nk'ingufu za 12V/5V n'izindi ngufu za kabiri) ari izisanzwe.
Umusaruro w'ikimenyetso cya motherboard:
Genzura niba insinga ziva kuri motherboard zijya kuri ecran ya LCD zidakora neza cyangwa zifite umuvuduko muke.
Koresha oscilloscope cyangwa multimeter kugira ngo upime niba umurongo w'ikimenyetso cya LVDS ufite umusaruro.
4. Isesengura ry'urusobe rw'amashanyarazi ya LCD
Reba niba ikibaho cya ecran driver (T-Con board) cyangiritse bigaragara (nk'imashini itwika cyangwa capacitor yangiritse).
Niba amashanyarazi menshi yangiza, amakosa akunze kugaragara ni aya:
Ihungabana ry'imicungire y'amashanyarazi ya IC.
Diode igenzura amashanyarazi cyangwa umuyoboro wa MOS uri mu muyoboro w'amashanyarazi wa ecran iratwikwa.
5. Isuzuma ry'uburyo bwo kurinda umuriro urenze urugero
Reba niba ecran yakozwe ifite imiyoboro irinda umuriro mwinshi (nk'ama-diode ya TVS, modules zo kubungabunga umuriro).
Iyo nta ruziga rwo kurinda rufite, amashanyarazi arenze urugero ashobora kugira ingaruka ku kintu gitwara ecran ya LCD.
Ugereranije ibicuruzwa bisa, emeza niba 12V yinjiye isaba igishushanyo cy'uburinzi bw'inyongera.
6. Gusubiramo amakosa no kuyagenzura
Niba ibintu bikwemereye, koresha amashanyarazi ashobora guhindurwa kugira ngo wigane 12V, wongere buhoro buhoro voltage (nka 24V) kandi urebe niba uburinzi bwatangiye cyangwa bwangiritse.
Simbuza ecran imwe ya LCD y'icyitegererezo urebe ko ikora neza hanyuma urebe niba ikora neza.
7. Umwanzuro n'ibitekerezo byo kunoza
Birashoboka ko umuntu agira umuvuduko ukabije w'amaraso:
Iyo voltage yinjiye idasanzwe cyangwa se circuit yo kurinda ibuze, volteji irenze urugero ishobora kuba impamvu.
Ni byiza ko umukoresha atanga raporo y'igenzura ry'adaptateri y'amashanyarazi.
Izindi nzira zishoboka:
Gutigita kw'ubwikorezi bituma insinga zirekura cyangwa zigasenyuka ibice byazo.
Ubusembwa bw'amashanyarazi adahindagurika cyangwa imiterere y'ibikoresho bituma chip ya ecran driver inanirwa.
8. Ingamba zo gukurikirana
Simbuza ecran ya LCD yangiritse hanyuma usane power board (nk'ugusimbuza ibice byahiye).
Ni byiza ko abakoresha bakoresha umuriro ugenzurwa cyangwa bagasimbuza adaptateri ya mbere.
Igishushanyo mbonera cy'umusaruro: ongeramo uruziga rwo kurinda umuriro urenze urugero (nk'aho icyuma cy'amashanyarazi cya 12V gihujwe na diode ya televiziyo ijyanye nayo).
