Dab tsi yog vim li cas rau qhov tsis ua tiav ntawm kev thauj khoom lossis kev sib txuas lus?

Cov laj thawj rau qhov tsis ua hauj lwm ntawm kev sib txuas lus thiab thauj khoom yog qhov qub, uas yuav tshwm sim los ntawm cov hauv qab no. Thov piv nrog lub lag luam raws li cov laj thawj hauv qab no:

1. Nco ntsoov tias kho vajtse ntawm lub kaw lus tswj tau zoo kaw haujlwm rau. (+ 5 v)

2. Tshawb xyuas thiab paub meej tias txoj kab txuas los siv los txuas tus maub los yog kab ncaj ncaj, thiab tsis hla kab.

3. Tshawb xyuas thiab paub meej tias cov kab txuas kev txuas ntxiv lawm thiab tsis muaj qhov xoob lossis poob tawm ntawm ob qho kawg.

4, CovLED npotswj software thiab lawv cov kev xaiv ntawm daim npav tswj los xaiv cov qauv khoom tsim kom raug, hom xa mus kom raug, chaw nres nkoj tus naj npawb tseeb, cov lej raug xa mus thiab cov software muab los ntawm kev hu xov tooj hloov daim duab kom raug teeb tsa cov kev tswj hwm cov khoom nruab rau ntawm qhov chaw nyob caij thiab txog qib kis.

5. Tshawb xyuas seb lub jumper cap yog xoob lossis tawm; Yog hais tias lub jumper cap yog tsis xoob, nco ntsoov tias lub jumper cap nyob hauv txoj hauv kev.

6. Yog tias lub chaw thau khoom tseem ua tsis tiav tom qab kev kuaj xyuas thiab kho dua tshiab, thov siv multimeter los ntsuas seb puas lub chaw nres nkoj ntawm lub computer txuas nrog lossis lub thev naus laus zis ntawm kev tswj hwm tau ua puas kom paub meej tias nws yuav tsum rov qab mus rau lub chaw tsim khoom siv computer lossis kho vajtse ntawm lub kaw lus tswj rau kev sim.

LED npo common fault solutions

Two, the LED npo just on the power when a few seconds of bright line or screen picture changed flowers?

Tom qab cov tshuaj ntsuam lub vijtsam txuas nrog lub khoos phis tawm, HUB qhov chaw faib khoom thiab lub vijtsam, nws yog qhov yuav tsum tau muab + 5V fais fab rau tus tuav tswj kom nws ua haujlwm ib txwm ua haujlwm (lub sijhawm no, tsis txhob txuas ncaj qha mus rau 220V voltage) Cov.

Thaum lub sijhawm tawm ntawm lub zog, txoj kab ci ci lossis "txaws npo" yuav tshwm nyob rau ntawm qhov screen rau ob peb lub sijhawm, uas yog cov xwm txheej ib txwm kuaj thiab ceeb toom rau tus neeg siv tias qhov screen tab tom pib ua haujlwm txhua zaus.Within 2 vib nas this, qhov tshwm sim cia li tshem tawm, qhov screen rau hauv lub xeev ua haujlwm tsis zoo.

Peb, Lub ntsiab lus ntawm tsis siv neeg lossis phau ntawv hloov teeb ci yog dab tsi?

Qhov hloov kho ci ci yog hais txog kev kho kom haum ntawm lub dimmest thiab ci ntsa iab tshaj qhov screen tuaj yeem tso tau, tsis yog qhov kev hloov kho tau zoo.Tiam sis qhov kev hloov kho lub teeb ci raws li lub teeb ci sib txawv yuav tsum tshwm nyob rau lub sijhawm sib txawv thiab qhov ua tiav tiav.LED npotswj system cia li kho rau ib qho kev xav tau yav dhau los kev ci ntsa iab.Manual brightness hloov kho yog hais txog kev ua haujlwm ntawm lubLED npo control system by the end user to make the LED npo reach a certain specified brightness.

Plaub, chav tswj hwm pom tshwm tag nrho lub vijtsam tsis ci, tsaus xim

1. Xyuas qhov muag pom seb txoj hlua hluav taws xob 26P ntawm nruab nrab ntawm lub hwj huam cable thiab lub rooj tsav xwm thiab qhov taw qhia lub teeb ntawm lub zog hluav taws xob yog dab tsi.

2. Siv cov multimeter ntsuas los ntsuas seb pawg ntsuas hluav taws xob puas muaj hluav taws xob ib txwm, thiab tom qab ntawd ntsuas seb qhov tso zis hluav taws xob ntawm lub zog hluav taws xob puas zoo ib yam. Yog tias tsis yog, nws raug txiav txim tias lub zog hluav taws xob tau tawg.

3. Ntsuas qhov ntsuas hluav taws xob ntawm lub zog hluav taws xob thiab kho qhov ntsuas qhov zoo (qhov zoo nyob ntawm lub zog hluav taws xob nyob ze qhov ntsuas lub teeb) ua kom lub voltage mus txog tus qauv.

Five, what is the reason why the LED npo appears all black?

Hauv kev tsim cov txheej txheem tswj kev tswj hwm, peb yuav qee zaum ntsib qhov tshwm sim uas covLED npoyog tag nrho cov dub.Qhov tib qho kev tshwm sim tuaj yeem tshwm sim los ntawm ntau yam sib txawv, thiab txawm tias cov txheej txheem tsaus nti ntawm qhov screen tuaj yeem sib txawv ntawm kev ua haujlwm rau kev ua haujlwm lossis ib puag ncig ib puag ncig.

Piv txwv li, nws yuav dhau los ua xim dub thaum nws siv rau, nws yuav dub thaum lub sijhawm thauj khoom, nws yuav dhau los ua dub tom qab xa mus, thiab lwm yam:

1. Thov xyuas kom meej tias txhua yam khoom siv (Hardware), suav nrog lub kaw lus tswj hwm, tau ua haujlwm kom zoo. (+ 5V, tsis txhob thim qhov kev sib txuas, kev txuas tsis raug)

2. Tshawb xyuas thiab rov hais dua seb qhov chaw nres nkoj kab puas siv los txuas rau tus maub los yog xoob lossis poob tawm. (Yog tias nws tau dub thaum lub sijhawm thauj khoom, nws zoo li yuav tshwm sim los ntawm qhov laj thawj no, uas yog, cov kab sib txuas lus tau xoob thiab cuam tshuam thaum lub sijhawm cov txheej txheem kev sib txuas lus, yog li lub vijtsam dub. Tsis txhob xav tias lub cev lub cev txav tsis tau, thiab txoj kab tsis tuaj yeem xoob. Thov pib saib, uas nws tseem ceeb heev kom daws qhov teeb meem sai sai.)

3. Tshawb xyuas thiab paub meej seb HUB faib board txuas nrogLED npothiab lub ntsiab tswj lag luam daim npav luam ntawv yog nruj nreem txuas thiab ntsaws rau hauv.
