Nyob Zoo Txhua Tus, Kuv tau muab lub Android TV Box no los kho nws thiab qhov kev tsis txaus siab yog tias nws yuav tsis qhib.
Raws li cov tsos mob ntxiv, kuv tau hais tias ob peb zaug dhau los, lub xov tooj yuav tsum tau ntswj kom ze rau lub hwj chim rau lub thawv kom qhib kom kuv thiaj paub tias qhov ua txhaum yog ib qho hauv lub hwj chim nkaus ntawm lub npov Android lossis hauv lub hwj huam mov cable.
Txhawm rau txheeb xyuas lub thawv Android thiab nws lub zog xa hluav taws xob, Kuv muaj lub charger zoo sib xws muaj thiab kuv siv nws los ua lub zog ntawm lub thawv thiab nws ua haujlwm raws li xav tau. Nrog rau qhov no, Kuv paub tias qhov teeb meem yog nrog lub charger yog li kuv tau txav kuv lub hom phiaj rau nws.
Txhawm rau pib tshuaj xyuas lub charger, kuv ntsaws nws rau hauv AC qhov hluav taws xob thiab kuv ntsuas qhov hluav taws xob ntawm nws cov zis. Qhov no yog 5V lub zog siv thiab kuv twv yuav raug hu tsis tau txais 5V tab sis tsuas yog qee qhov kev hloov pauv ntawm ob peb puas millivolts.
Qhov no tau lees tias kuv tsis ntseeg tias lub hwj chim ua tsis raug yog li kuv tau pib qhib nws thiab tshuaj xyuas qhov ua txhaum.

Kauj Ruam 1: Qhib Lub Hwj Huam Fais Fab
Hmoov tsis zoo, lub thawv hluav taws xob tsis yooj yim qhib. Nws tsis muaj cov ntsia hlau sab nraud raws li nws tau nias haum thiab tom qab ntawd ua ke.
Txhawm rau qhib nws, Kuv tau siv lub taub hau taub hau ntswj ua ke nrog rab riam muaj peev xwm txhawm rau txhawm rau lo kua nplaum rau ntawm qhov sib koom ua ke thiab txhawm rau qhib ob lub kaum.
Nyob ntawm cov chaw tsim khoom thiab hom kua nplaum uas lawv siv, txheej txheem qhib no tuaj yeem nyuaj thiab qee zaum, nws yuav txawm yog ib txoj hauv kev rau siab ua thiab rooj plaub tuaj yeem ua rau puas tsuaj heev uas nws yuav tsis muaj peev xwm yuav tsum tau muab rov qab ua ke.
Luckily rau kuv, cov kua nplaum tso tawm sai heev, yog li kuv tsoo qhib rooj plaub thiab kuv tshem tawm lub rooj sib tham ntawm sab hauv.
Cov kab hluav taws xob tso tawm tau muab tso rau ntawm lub rooj tsavxwm thiab AC txuas tau ua los ntawm ob tus pin uas tau nias rau hauv cov kab laug sab. Qhov no yog kev tsim kho ib txwm yog li rooj plaub tuaj yeem raug faib qhib yog xav tau.
Tam sim no nrog lub rooj tsav xwm tau muab rho tawm, kuv xub ua qhov kev tshuaj xyuas nws, nrhiav rau txhua qhov teeb meem pom tseeb xws li bulging capacitors, ib qho cim hlawv, tawg sib txuas, lossis zoo ib yam tab sis txhua yam zoo li OK.
Kauj Ruam 2: Kuaj Cov Khoom Siv Hluav Taws Xob
Txhawm rau ntsuas tawm cov kab hluav taws xob tso tawm, Kuv hloov kuv lub ntsuas cua mus rau hom txuas mus txuas ntxiv thiab kuv tau txheeb xyuas qhov kev sib txuas ntawm ob qho ntawm cov coj mus rau lub hwj chim nkaus. Raws li kuv xav tau, kuv tsuas yog tau txais txuas ntxiv ntawm qhov txuas zoo tab sis tsis yog ntawm cov xov hlau tsis zoo.
Qhov no piav qhia qhov hloov pauv me me uas peb tau pom ua ntej thaum peb sim them lub roj teeb txuas nrog rau ntawm phab ntsa vim tsuas yog qhov hluav taws xob zoo tau txuas nrog thiab qee qhov ua rau ntab ntab tau ntsuas.
Txhawm rau txheeb xyuas tias lub charger them hluav taws xob tau ua haujlwm tiag tiag raws li qhov xav tau, kuv yuav tsum sim nws thaum tsis nyob ntawm rooj plaub yog li kuv tau siv cov kais dej thiab cov kab hluav taws xob AC nrog cov xov hlau nthuav tawm los txuas lub charger PCB rau 220V.
Thov ceev faj thaum ua tej yam zoo li no! AC tuag taus thiab tuaj yeem tua koj tau yooj yim yog tias koj tsis ceev faj. Txhawm rau tiv thaiv cov hlau lead thiab kuv los ntawm kev kov ib qho ntawm cov xov hlau nyob, Kuv tau siv daim kab xev hluav taws xob cais cov hlau lead.
Thaum tseem tau ceev faj heev, Kuv ntsuas qhov ntsuas hluav taws xob ntawm ob lub ntsiab lus qhov twg cov kab hluav taws xob tau muab tso rau ntawm lub rooj tsavxwm thiab kuv tuaj yeem ntsuas qhov ntsuas hluav taws xob tag nrho raws li ntsuas ntawm lub zog 5V. Qhov no txhais tau tias PCB tau ua haujlwm zoo thiab tsuas yog lub xov tooj yog qhov teeb meem.
Kauj Ruam 3: Re-solder Power Jack
Txij li qhov kev sib txuas tsis zoo ntawm lub hwj chim tau tshwm sim ntau heev, Kuv xav tshuaj xyuas thiab pom tias qhov no yog li cas yog li kuv txiav ib daim ntawm cov xov hlau tso tawm ntawm ob peb centimeters los ntawm lub jack thiab nthuav nws cov tooj liab.
Kuv siv kuv lub ntsuas cua dua los tshuaj xyuas qhov txuas ntxiv thiab lub sijhawm no, ob lub xov hlau tau pom kev sib txuas zoo nrog PCB. Kuv xav tias kuv tej zaum tau txiav tawm qhov tsis zoo ntawm txoj hlua yog li kuv tshem lub jack los ntawm daim uas seem thiab hle cov yas yas los ntawm ib puag ncig nws.
Qhov no nthuav tawm nws cov neeg sib cuag thiab nrog me ntsis ntawm cov laug, Kuv tau siv cov xov hlau rov qab rau nws kom ntseeg tau tias ua kom zoo ib yam qhov sib txuas qhov twg cov xaim zoo txuas nrog rau hauv nruab nrab thiab qhov tsis zoo rau sab nraud ntawm lub zog txuas.
Thaum qhov ntawd ua tiav, Kuv tau muab tso ua ke ob ntu ib nrab ntawm cov khoom siv hluav taws xob thiab kuv txuas nws rau ntawm phab ntsa los ntsuas nws. Ua rau kuv xav tsis thoob, qhov hluav taws xob tso tawm tseem yog ob peb puas millivolts thiab kuv paub tias txoj hlua yuav tsum tau hloov tag nrho.
Kauj Ruam 4: Hloov Tag Nrho Cov Kab (xaiv tau)
Kuv tshawb xyuas kuv cov kab hluav taws xob thiab kuv pom ib qho uas yuav luag zoo ib yam li ib qho ntawm lub hwj chim. Kuv qhib rooj plaub ib zaug ntxiv thiab siv kuv cov hlau txuas, kuv xub tshem lub xov hlau qub, kuv hle qhov kawg ntawm tus tshiab thiab kuv muab nws tso rau hauv qhov chaw.
Cov txheej txheem zoo ib yam tau rov ua dua ntawm lwm sab, qhov uas kuv xub xub tshem lub jack los ntawm qhov kawg ntawm cov xov tooj qub, hle cov xov hlau ntawm tus xov tooj tshiab thiab muab lub xov tooj txuas rau lub xov tooj tshiab.
Tom qab ntawd kuv nias haum cov ntaub ntawv ntawm lub zog hluav taws xob thiab txuas nws mus rau phab ntsa yog li kuv tuaj yeem sim nws tawm. Lub sijhawm no, qhov ntsuas hluav taws xob tau raug ntawm 5V thiab cov khoom tau rov qab ua lag luam.
Kauj Ruam 5: Sib Sau Cov Ntaub Ntawv Nrog Kub Kub
Txhawm rau kho qhov kev kho kom tiav thiab ruaj ntseg rooj plaub, Kuv tau siv me ntsis ntawm cov kua nplaum kub uas kuv tau siv nws qhov uas cov kab hluav taws xob tawm los ntawm cov khoom siv, Kuv tau ua tus tuav tawm ntawm cov kua nplaum kub mus rau DC jack los tiv thaiv kev sib txuas thiab kuv tau ntxiv me ntsis ntawm cov kua nplaum kub rau hauv rooj plaub ib yam yog li nws nyob ruaj ntseg.
Qhia rau kuv paub hauv cov lus yog tias koj muaj lus nug lossis tswv yim, nco ntsoov nyiam Cov Lus Qhia, sau npe rau kuv li YouTube channel rau ntau cov vis dis aus thiab kuv yuav pom koj txhua tus nyob rau tom ntej no.
Tsis tas li, txheeb xyuas qee qhov ntawm kuv lwm Cov Ntawv Qhia thiab:
