Kev ceev faj rau kev saib xyuas ntawm LCD npo:
1. Pib nrog tej yam yooj yim ua ntej:
Txhawm rau daws qhov teeb meem, koj yuav tsum pib nrog qhov yooj yim tshaj plaws, uas yog, ua ntej kuaj xyuas qhov chaw ib puag ncig sab nraud (qhov teeb meem pom, lub zog hluav taws xob, kev sib txuas, thiab lwm yam), thiab tom qab ntawd tshawb xyuas qhov chaw sab hauv ntawm cov zaub (kev sib txuas, cov khoom siv xim, cov khoom zoo, qhov taw qhia lub teeb xwm txheej, thiab lwm yam), qhov no yog qhov tsim nyog rau kev tsom mus rau qhov kev txiav txim thiab qhov chaw ntawm qhov teeb meem, peb yuav tsum tau xyuam xim rau nws, tsuas yog tom qab ua tib zoo soj ntsuam tuaj yeem txiav txim thiab kho.

2. Xav ua ntej thiab tom qab ntawd ua raws li qhov tshwm sim:
Raws li qhov tshwm sim ntawm qhov teeb meem, thawj zaug xav txog qhov twg yuav pib thiab yuav ua li cas khiav lag luam, thiab tom qab ntawd ua tiav kev ua haujlwm txij nkawm tiag tiag. Koj yuav tsum sab laj nrog cov ntaub ntawv tseem ceeb (cov phau ntawv tu, thiab lwm yam) kom ntau li ntau tau, thiab tom qab nkag siab txog cov kev xav tau thiab cov yam ntxwv ntawm daim ntawv thov, tshuaj xyuas thiab txiav txim raws li qhov xwm txheej tiag tiag thiab muab koj tus kheej kev paub thiab kev paub dhau los ua ntej kev saib xyuas.
3. Static ua ntej, ces dynamic:
Qhov kev tshuaj xyuas zoo li qub yog kev tshuaj xyuas ua ntej lub tshuab ua haujlwm. Thaum nws tau lees paub tias qhov kev tshuaj xyuas zoo li qub yog qhov tseeb, qhov kev tshuaj xyuas dynamic tuaj yeem ua tau los ntawm kev siv hluav taws xob. Yog tias pom muaj qhov txawv txav xws li cov pa luam yeeb, kaw nws tam sim ntawd thiab ua qhov kev tshuaj xyuas zoo li qub dua. Qhov no tuaj yeem zam kev puas tsuaj los ntawm kev siv lub tshuab ua kom tsis muaj zog vim tsis paub txog qhov xwm txheej.
4. Ua ntej thiab tom qab ntawd kho qhov vuam:
Thaum lub monitor ntub dej, poob los yog muaj plua plav ntau hauv, cov dej noo los yog plua plav tuaj yeem ua rau corrosion rau lub rooj tsav xwm ntawm lub monitor. Nyob rau hauv cov ntaub ntawv no, nws yog feem ntau yuav tsum tau ntxuav lub sab hauv Circuit Court board ntawm cov zaub ua ntej, thiab tom qab ntawd ua kev kho welding ntawm dummy soldering ib feem ntawm lub Circuit Court board. Tom qab ntxuav thiab kho vuam, qee qhov teeb meem tuaj yeem raug tshem tawm.
5. Tua lub hwj chim ua ntej overhauling:
Txij li cov kab hluav taws xob sab hauv ntawm cov khoom siv tag nrho siv cov chips sib xyaw ua ke, lawv qhov ua haujlwm voltage tsuas yog li 3V, uas yooj yim rau tawg los ntawm hluav taws xob zoo li qub. Yog li ntawd, thaum ntsaws rau hauv cov connectors sab hauv ntawm cov zaub los yog vuam cov khoom nyob rau hauv lub Circuit Court board, tua lub hwj chim ua ntej, thiab ces xyuas lub Circuit Court board ntawm lub monitor dua.
6, fais fab mov ua ntej, Circuit Court:
Raws li kev paub dhau los, qhov teeb meem tus nqi ntawm cov khoom siv hluav taws xob suav nrog feem ntau ntawm tag nrho lub tshuab. Muaj ntau yam teeb meem tshwm sim los ntawm kev siv hluav taws xob, yog li kev kho cov khoom siv hluav taws xob ua ntej tuaj yeem tau txais ob zaug qhov tshwm sim nrog ib nrab ntawm kev siv zog.
