Isesengura ryimikorere ya 12V ikurikirana LCD ecran

1. Emeza ikosa

Reba uko reaction imaze gukurikiranwa na moteri (nko kumenya niba urumuri rwinyuma rwaka, niba hari ibirimo kwerekana, amajwi adasanzwe, nibindi).

Reba niba ecran ya LCD ifite ibyangiritse kumubiri (ibice, kumeneka kw'amazi, ibimenyetso byo gutwika, nibindi).

2. Kugenzura ibyinjijwe

Gupima voltage yinjira: Koresha multimeter kugirango umenye niba voltage yinjiza ihagaze neza kuri 12V.

Niba voltage iri hejuru ya 12V (nko hejuru ya 15V), irashobora kwangizwa na volvoltage.

Reba niba amashanyarazi adahinduka cyangwa ibikoresho bitanga amashanyarazi bidasanzwe.

Reba amashanyarazi atanga polarite: Emeza niba inkingi nziza kandi mbi yimigozi yimbaraga zahujwe muburyo butandukanye (guhuza kwinyuma bishobora gutera inzira ngufi cyangwa gutwika).

3. Reba imirongo yimbere

Kugenzura ikibaho cy'amashanyarazi:

Reba niba hari ibice byahiye ku kibaho cyamashanyarazi (nka capacitor bulge, IC chip yaka, fuse yavuzwe).

Gerageza niba ibisohoka voltage yumurongo wamashanyarazi (nka 12V / 5V nizindi voltage ya kabiri) nibisanzwe.

Ikimenyetso cya kibaho gisohoka:

Reba niba insinga ziva kuri kibaho kugeza kuri LCD ecran ari mbi cyangwa izengurutse-bigufi.

Koresha oscilloscope cyangwa multimeter kugirango umenye niba umurongo wa signal ya LVDS ufite ibisohoka.

4. Isesengura rya LCD ya ecran ya shoferi

Reba niba ikibaho cyabashoferi (T-Con board) cyangiritse (nko gutwika chip cyangwa kunanirwa kwa capacitor).

Niba kurenza urugero bitera ibyangiritse, ingingo zisanzwe ni:

Gucunga ingufu IC gusenyuka.

Umuyoboro wa voltage diode cyangwa umuyoboro wa MOS muri ecran yumuriro wumuriro urashya.

5. Gusuzuma uburyo bwo gukingira birenze urugero

Reba niba moniteur yarakozwe hamwe na sisitemu yo gukingira birenze urugero (nka diode ya TVS, modules ya voltage stabilisation).

Niba nta soko yo gukingira, kurenza urugero birashobora kugira ingaruka byoroshye kuri LCD ya ecran yo gutwara.

Ugereranije ibicuruzwa bisa, wemeze niba ibyinjira 12V bisaba ubundi buryo bwo kurinda.

6. Gusubiramo amakosa no kugenzura

Niba ibintu byemewe, koresha amashanyarazi ashobora guhinduka kugirango wigane 12V yinjiza, wongere buhoro buhoro voltage (nka 24V) hanyuma urebe niba uburinzi bwatewe cyangwa bwangiritse.

Simbuza icyitegererezo kimwe LCD ecran hamwe no kwemeza imikorere myiza hanyuma ugerageze niba ikora bisanzwe.

7. Imyanzuro nibyifuzo byo kunoza

Ibishoboka byo gukabya:

Niba ibyinjira byinjira bidasanzwe cyangwa uruziga rwo kurinda rwabuze, kurenza urugero birashoboka.

Birasabwa ko uyikoresha atanga raporo yubugenzuzi bwimbaraga.

Ibindi bishoboka:

Kunyeganyega kwubwikorezi bitera kurekura umugozi cyangwa gutesha agaciro ibice.

Imiterere ya electrostatike ihagaze cyangwa umusaruro itera chip ya ecran ya ecran kunanirwa.

8. Gukurikirana ingamba

Simbuza ecran ya LCD yangiritse hanyuma usane ikibaho cyamashanyarazi (nko gusimbuza ibice byatwitse).

Birasabwa ko abakoresha bakoresha amashanyarazi yagenwe cyangwa bagasimbuza adapt yumwimerere.

Igishushanyo mbonera cyibicuruzwa birangiye: ongeramo umuzenguruko urenze urugero (nka 12V yinjiza itumanaho ihujwe na parike ya TVS ibangikanye).
