1. Xaqiiji dhacdada khaladka ah
Hubi falcelinta ka dib marka kormeeruhu daaro (sida in iftiinka dambe uu ifayo, haddii ay jiraan wax muuqaal ah, cod aan caadi ahayn, iwm.).
U fiirso in muraayadda LCD ay leedahay dhaawac jireed ( dildilaacyo, dareere dareere ah, calaamadaha gubashada, iwm.).
2. Xaqiiji gelinta tamarta
Cabbir tamarta wax gelinta: Isticmaal multimeter si aad u ogaatid in taranta dhabta ahi ay tahay mid deggan 12V.
Haddii danabku uu aad uga sarreeyo 12V (sida korka 15V), waxaa laga yaabaa in ay waxyeelo gaarto koronto-dhaafka.
Hubi in adabtarada korontadu ama soo saarida qalabka korontada ay tahay mid aan caadi ahayn.
Hubi polarity-ka sahayda korantada: Xaqiiji in tiirarka togan iyo kuwa taban ee is dhexgalka korantadu ay ku xiran yihiin gadaal (xiriirka gadaale wuxuu keeni karaa wareeg gaaban ama gubasho).
3. Hubi wareegyada gudaha
Hubinta looxa korontada:
Hubi in ay jiraan waxyaabo gubtay oo ku yaal sabuuradda korontada (sida capacitor bulge, IC chip gubashada, fiyuuska la afuufay).
Tijaabi in korantada wax soo saarka ee guddiga korantada (sida 12V/5V iyo danab kale oo sare) ay caadi tahay.
Soo saarida signalka Motherboard-ka:
Iska hubi in xadhkaha Motherboard-ka ilaa shaashadda LCD ay liitaan ama ay gaaban yihiin.
Isticmaal oscilloscope ama multimeter si aad u cabbirto in xariiqda calaamadda LVDS ay soo saartay.
4. Falanqaynta wareegga darawalka shaashadda LCD
Hubi in boodhka darawalka shaashadda (T-Con board) uu si cad u dhaawacmay (sida gubasho gubasho ama capacitor failure).
Haddii korontadu ay keento dhaawac, dhibcooyinka caamka ah waa:
Maareynta awooda IC burbur.
Diode-hagaha korantada ama tuubada MOS ee wareegga korontada ee shaashadda waa gubtay.
5. Qiimaynta habka ilaalinta xad-dhaafka ah
Hubi in kormeeruhu loogu talagalay iyadoo leh wareegyada ilaalinta korantada ee xad-dhaafka ah (sida TVS-ga, qaybaha xasilinta korantada).
Haddii aysan jirin wareegga ilaalinta, korontadu waxay si fudud si toos ah u saameyn kartaa qaybta wadista shaashadda LCD.
Isbarbardhigga alaabada la midka ah, xaqiiji in gelinta 12V ay u baahan tahay naqshad ilaalin dheeraad ah.
6. Soo noqoshada cilladda iyo xaqiijinta
Haddii shuruuduhu oggolaadaan, isticmaal koronto la hagaajin karo si aad u ekaysiiso gelinta 12V, si tartiib tartiib ah u kordhi danabka (sida 24V) oo fiirso haddii ilaalintu kicisay ama dhaawacday.
Ku beddel muraayadda LCD-ga moodada ah ee la mid ah caddaynta waxqabadka wanaagsan oo tijaabi inay si caadi ah u shaqaynayso.
7. Gabagabada iyo talooyinka hagaajinta
Suurtagalnimada cadaadis xad dhaaf ah:
Haddii korontadu ay tahay mid aan caadi ahayn ama wareegga ilaalinta uu maqan yahay, kororka korontadu waa sabab macquul ah.
Waxaa lagula talinayaa isticmaaluhu inuu bixiyo warbixinta kormeerka adabtarada korantada.
Fursadaha kale:
Gariirka gaadiidku wuxuu keenaa dabcinta fiilada ama kala-baxa qaybaha.
Cilladaha korantada ee taagan ama soo saarista ayaa sababa in dareewalka shaashadda uu fashilmo.
8. Tallaabooyinka daba-galka ah
Beddel shaashadda LCD ee dhaawacan oo hagaaji looxa korontada (sida beddelka qaybaha gubtay).
Waxaa lagula talinayaa dadka isticmaala inay isticmaalaan koronto nidaamsan ama ay beddelaan adabtarada asalka ah.
Dhammaadka naqshadeynta badeecada: ku dar wareegga ilaalinta korantada (sida 12V gelinta terminalka oo ku xiran isku midka ah TVS diode).
