LED qhia inevitably muaj malfunctions thaum siv. Thaum muaj teeb meem tshwm sim, cov zaub yuav tsis ua haujlwm zoo, cuam tshuam rau kev ua lag luam. Kev saib xyuas tsis tu ncua ntawm LED cov ntxaij vab tshaus tuaj yeem txo qhov poob los ntawm kev ua haujlwm tsis zoo.
LED zaub yog tsim los ntawm ib tus neeg LED modules. Nws cov qauv yooj yim muaj xws li cov zaub nto (teeb pom kev zoo), PCB (circuit board), thiab tswj qhov chaw (IC tivthaiv nto). Hais txog LED zaub cov lus qhia kho, cia peb tham ua ntej txog kev ua haujlwm tsis zoo. Feem ntau ua haujlwm tsis zoo xws li: ib nrab "tuag LEDs," "kab ntsig-zoo li" LEDs, ib nrab xim thaiv qhov poob, ib nrab ntawm lub vijtsam dub, loj - cheeb tsam dub npo, ib nrab cov ntawv nyeem, thiab lwm yam. Yog li koj yuav kho cov kev ua haujlwm me me no li cas? Ua ntej, npaj cov cuab yeej kho tsim nyog. Tsib lub cuab yeej tseem ceeb rau kev kho cov duab LED yog: tweezers, phom cua kub, cov hlau nplaum, multimeter, thiab cov ntawv xeem; Lwm cov ntaub ntawv pabcuam muaj xws li: solder paste (solder wire), soldering accelerator, tooj liab hlau, thiab kua nplaum.
Cov teeb meem tshwm sim muaj xws li:
1. Cov teeb meem cuam tshuam. Yog tias cov ntaub ntawv hauv computer tsis tuaj yeem tshwm sim, sim xyuas lub cable ua ntej
2. Qhov teeb meem ntawm kev siv fais fab. LED zaub siv qhov tsawg-voltage, siab- fais fab mov tam sim no, tsis txawv ntau ntawm DC fais fab mov.
3. Qhov teeb meem tsav tsheb. Yog tias tsis muaj kab lossis kab qhia dab tsi, nws qhia tau hais tias muaj teeb meem nrog tus tsav tsheb sib txuas (chip). Hloov cov nti yuav daws tau qhov teeb meem.
4. Zaub qhov teeb meem. Kev siv lub LED ntev ntev yuav ua rau muaj kev puas tsuaj thiab kev laus, yuav tsum tau kho lossis hloov.
Feem ntau LED screen kho faults muaj xws li:
1. Ib feem ntawm "Lub Teeb Tuag" teeb meem
Ib feem "tuag teeb" yog hais txog ib lossis ntau lub LEDs ntawm LED zaub screen tsis teeb pom kev. Qhov no tuaj yeem muab faib ua tiav tsis yog - teeb pom kev zoo thiab ib nrab xim tsis yog - teeb pom kev zoo. Feem ntau, qhov no yog vim muaj teeb meem nrog lub teeb nws tus kheej, xws li kev puas tsuaj rau cov dej los yog cov nti RGB puas. Txoj kev kho yog yooj yim: hloov nws nrog ib qho khoom seem LED muab los ntawm lub Hoobkas. Cov cuab yeej siv muaj xws li tweezers thiab rab phom kub. Tom qab hloov nrog qhov seem LED, nws yuav tsum tau kuaj dua nrog daim npav xeem. Yog tias tsis muaj teeb meem, kev kho tiav.
2. LED Loj Loj Kho: Qhov teeb meem "Caterpillar" teeb meem "kab ntsig" yog ib lo lus piv txwv uas hais txog qhov tshwm sim uas ntev, tsaus nti, ci kab txaij tshwm rau ntawm qee qhov chaw LED thaum lub LED zaub yog powered tab sis tsis muaj cov khoom nkag. Cov kab txaij no feem ntau yog liab. Lub hauv paus ua rau yog ib qho xau nti hauv LED lossis luv luv Circuit Court nyob rau hauv kab rov tav tso zis transistor (HIP) Circuit Court nyob rau sab nraum qab ntawm cov zaub, nrog rau yav dhau los ua ntau dua. Feem ntau, koj tuaj yeem siv rab phom cua kub los tshuab cua kub raws li qhov tsis muaj xim "kab ntsig" ntawm cov xau LED. Thaum tshav kub mus txog qhov teeb meem LED, qhov teeb meem feem ntau daws tau vim tias lub tshav kub ua rau cov xaim nti txuas qhib. Txawm li cas los xij, tseem muaj kev phom sij. Tsuas yog nrhiav cov LED xau thiab hloov nws siv txoj kev tau piav qhia saum toj no. Yog hais tias lub luv luv Circuit Court nyob rau hauv lub HIP Circuit Court nyob rau sab nraum qab ntawm lub zaub, koj yuav tsum tau siv ib tug multimeter los ntsuas qhov cuam tshuam IC pins thiab hloov lub IC nrog ib tug tshiab.
3. LED Kev Kho Kho Loj Loj: Ib nrab xim thaiv tsis pom Qhov kev ua txhaum no feem ntau tshwm sim. Thaum lub vijtsam LED ua si ib txwm, ib qho me me ntawm qhov tawm - xim thaiv tshwm. Qhov teeb meem no feem ntau yog tshwm sim los ntawm IC tswj cov xim ntawm qhov thaiv ntawd hlawv. Qhov kev daws teeb meem yog hloov nws nrog IC tshiab.
4. LED Loj Kho Kho: Ib nrab thiab Loj -Tej Chaw Dub Cov ntxaij vab tshaus Lub vijtsam dub yog hais txog qhov tshwm sim uas ib lossis ntau lub LED modules tsaus nti tag nrho thaum lub sijhawm ua haujlwm ntawm LED. Ob peb qhov tsaus nti LED modules hu ua ib nrab cov ntxaij vab tshaus dub, thaum lub cheeb tsam loj dua hu ua loj - cheeb tsam dub screen. Thaum qhov no tshwm sim, thawj yam uas yuav tsum tau xav txog yog lub hwj chim mov. Xyuas seb lub teeb qhia lub zog LED puas ua haujlwm zoo. Yog hais tias qhov taw qhia lub teeb tsis nyob rau, lub hwj chim mov yuav faulty; hloov nws nrog lub hwj huam mov ntawm cov wattage sib raug yuav daws tau qhov teeb meem. Kuj xyuas seb lub hwj chim cable ntawm LED module sib raug rau lub vijtsam dub yog xoob; Feem ntau, tsuas yog rov kho lub cable tuaj yeem daws qhov teeb meem ntawm qhov screen dub no.
5. LED Loj Kho Kho: Ib feem Garbled Characters Hom kev ua txhaum no yog qhov nyuaj dua. Nws hais txog qhov pom ntawm qhov tsis sib haum xeeb, tsis xwm yeem, thiab muaj peev xwm random flickering xim blocks hauv thaj chaw hauv cheeb tsam ntawm LED zaub thaum lub sijhawm ua si. Txhawm rau daws qhov teeb meem no, ua ntej kos lub teeb liab cable txuas. Xyuas yog tias lub ribbon cable raug hlawv tawm, lub network cable yog xoob, thiab lwm yam. Nyob rau hauv kev kho, nws tau pom tias txhuas -magnesium hlau ribbon cables yog heev burnout, thaum ntshiab tooj liab ribbon cables muaj ib tug ntev lifespan. Yog tias tag nrho cov teeb liab txuas tau raug kuaj xyuas thiab pom tias ua haujlwm zoo, ces swapping qhov teeb meem LED module nrog lub zeem muag uas ua haujlwm tau zoo tuaj yeem txiav txim siab seb lub LED module sib raug rau qhov chaw ua si txawv txav puas. Qhov ua rau muaj kev puas tsuaj feem ntau yog teeb meem IC, uas yog qhov nyuaj rau kev kho thiab yuav tsum tau sab laj nrog cov kws tshaj lij LED tshuaj ntsuam kho cov neeg ua haujlwm.
