Tsom teeb pom kev tiv thaiv kev tiv thaiv
Rau qhov kev tiv thaiv kom pom txoj kev ntawm lubzaub screen, peb yuav tsum tau teem lub multimeter mus rau qhov tsis kam.Ua ntej, peb yuav tsum kuaj xyuas tus nqi tiv thaiv los ntawm qee qhov taw tes ntawm lub rooj tsav xwm ib txwm muaj rau hauv av, thiab tom qab ntawd peb yuav tsum kuaj seb puas muaj qhov sib txawv ntawm qhov sib txawv ntawm tib lub ntsiab lus ntawm lwm lub rooj tsav xwm Circuit Court thiab tus nqi ib txwm ua haujlwm.Yog tias muaj qhov sib txawv, peb yuav paub qhov ntau ntawm qhov teeb meem nrog lub vijtsam zaub, txwv tsis pub peb yuav tsis quav ntsej nws.
Muab qhov screen voltage nrhiav kom tau txoj kev
Qhov ntsuas qhov ntsuas hluav taws xob ntawm lub vijtsam zaub yog teeb tsa lub multimeter rau qhov ntsuas hluav taws xob, kuaj xyuas qhov hluav taws xob hauv av ntawm qhov xav tias muaj teeb meem hauv Circuit Court taw tes, thiab muab piv rau yav dhau los saib seb nws puas yog qhov qub.Li no, qhov teeb meem tuaj yeem txheeb xyuas tau yooj yim.
Short circuit detection method for display screen
Qhov kev tshuaj ntsuam xyuas luv luv Circuit Court yog los teeb tsa lub multimeter mus rau lub luv luv Circuit Court detection iav, thiaj li xyuas seb puas muaj qhov tshwm sim luv luv.Yog tias pom muaj hluav taws xob luv luv, nws yuav tsum tau daws tam sim ntawd.luv luv Circuit Court ntawm cov zaub screen kuj yog feem ntauLED zaub moduletxhaum.Kuj!Kev kuaj xyuas luv luv yuav tsum tau ua thaum lub tshuab hluav taws xob raug kaw kom tsis txhob ua rau lub tshuab hluav taws xob puas.
Tso saib qhov ntsuas qhov ntsuas qhov ntsuas qhov ntsuas qhov ntsuas
Txoj kev ntsuas qhov ntsuas hluav taws xob poob qis yog los kho cov multimeter mus rau diode voltage rau kev tshawb nrhiav downshift, vim tias tag nrho cov ICs nyob rau hauv lub vijtsam zaub yog tsim los ntawm ntau chav tsev, yog li thaum tam sim no dhau los ntawm qee tus pin, yuav muaj qhov poob qis. pe pin.Raws li ib txwm muaj, qhov hluav taws xob poob ntawm IC pins ntawm tib tus qauv zoo sib xws.
Cov txheej txheem kev saib xyuas saum toj no rau LED cov ntxaij vab tshaus tuaj yeem kuaj tsis tu ncua kom tsis txhob muaj kev puas tsuaj rau lub vijtsam.Qhov no tsis tsuas yog ncua nws lub sijhawm siv, tab sis tseem txuag cov nuj nqis uas tsis tsim nyog.Vim tias qee qhov LED zaub screen manufacturers tsuas yog muab kev pab cuam tom qab muag rau ib mus rau ob xyoos, yog tias kev saib xyuas rov ua dua tom qab qhov kev pab cuam tom qab muag, yuav muaj nqi ntxiv.
