1. Xaqiiji dhacdada cilladda
Hubi falcelinta ka dib marka shaashadda la shido (sida in iftiinka dambe uu dhalaalayo, haddii ay jiraan wax muujinaya, cod aan caadi ahayn, iwm.).
Fiiri in shaashadda LCD-ga ay leedahay dhaawac jireed (dildilaac, daadasho dareere ah, calaamado gubasho, iwm.).
2. Xaqiiji gelinta korontada
Cabbir danabka gelinta: Isticmaal multimeter si aad u ogaato in danabka gelinta dhabta ahi uu deggan yahay 12V.
Haddii danabku aad uga sarreeyo 12V (sida ka sarreeya 15V), waxaa laga yaabaa inuu waxyeello u geysto danab xad-dhaaf ah.
Hubi in qalabka korontada ku shaqeeya ama qalabka korontada ku shaqeeya uu yahay mid aan caadi ahayn.
Hubi kala duwanaanshaha korontada: Xaqiiji in tiirarka togan iyo kuwa taban ee is-dhexgalka korontada ay ku xiran yihiin si rogan ah (xidhiidhka rogan wuxuu sababi karaa wareeg gaaban ama gubasho).
3. Hubi wareegyada gudaha
Hubinta guddiga korontada:
Hubi in ay jiraan qaybo guban oo ku yaal guddiga korontada (sida kororka capacitor-ka, gubista chip-ka IC, fiyuuska la qarxiyay).
Tijaabi in danabka soo baxaya ee looxa korontada (sida 12V/5V iyo danab kale oo labaad) uu yahay mid caadi ah.
Soo saarista calaamadda Motherboard-ka:
Hubi in fiilooyinka ka imanaya motherboard-ka ilaa shaashadda LCD-ga ay liitaan ama ay yihiin kuwo aan wareeg lahayn.
Adeegso oscilloscope ama multimeter si aad u cabbirto in xariiqda calaamadda LVDS ay soo saarto iyo in kale.
4. Falanqaynta wareegga darawalka shaashadda LCD
Hubi in looxa darawalka shaashadda (looxa T-Con) uu si cad u burburay (sida gubista jajabka ama cilladda capacitor-ka).
Haddii danab xad-dhaaf ah uu waxyeello geysto, qodobbada cilladaha caadiga ah waa:
Kala-goynta maaraynta korontada IC.
Diode-ka hagaya danabka ama tuubada MOS ee ku jirta wareegga korontada shaashadda ayaa la gubaa.
5. Qiimaynta habka ilaalinta danab xad-dhaafka ah
Hubi in kormeeraha loogu talagalay wareegyada ilaalinta danab-dhaafka ah (sida diode-yada TVS, modules-yada xasilinta danabka).
Haddii uusan jirin wareeg ilaalin ah, danab xad-dhaaf ah ayaa si toos ah u saameyn kara 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 xaaladdu saamaxdo, isticmaal koronto la hagaajin karo si aad u sawirto gelinta 12V, si tartiib tartiib ah u kordhi danabka (sida 24V) oo fiiri in ilaalintu ay kicisay ama ay waxyeelloowday.
Ku beddel shaashadda LCD ee isla nooca ah xaqiijinta waxqabadka wanaagsan oo tijaabi inay si caadi ah u shaqaynayso.
7. Gunaanad iyo talooyin ku saabsan horumarinta
Suurtagalnimada cadaadiska xad-dhaafka ah:
Haddii danabka la gelinayo uu yahay mid aan caadi ahayn ama wareegga ilaalinta maqan yahay, danab xad-dhaaf ah ayaa sababi kara.
Waxaa lagu talinayaa in isticmaaluhu bixiyo warbixin kormeer ah oo ku saabsan adabtarada korontada.
Suurtagalnimada kale:
Gariirka gaadiidku wuxuu sababaa dabcinta fiilada ama kala furfurka qaybaha.
Cilladaha korontada ku shaqeeya ama wax soo saarka ee taagan ayaa sababa in jajabka darawalka shaashadda uu xumaado.
8. Tallaabooyinka dabagalka
Beddel shaashadda LCD-ga ee dhaawacantay oo hagaaji guddiga korontada (sida beddelka qaybaha gubtay).
Waxaa lagu talinayaa in dadka isticmaala ay isticmaalaan koronto la nidaamiyay ama ay beddelaan adapter-kii asalka ahaa.
Dhammaadka naqshadeynta badeecada: ku dar wareegga ilaalinta danab xad-dhaafka ah (sida terminal-ka gelinta 12V ee ku xiran diode-ka TVS ee isbarbar socda).
