Kuv xav hloov lub teeb pom kev ntawm LED los ntawm amber rau xiav, liab lossis dawb. Liab yuav yog qhov zoo kom tsis txhob cuam tshuam koj lub zeem muag hmo ntuj. Tab sis kuv tsis muaj ib qho LEDs uas yuav ua haujlwm ntawm qhov tsav hluav taws xob tau muab.: (Los ntawm qhov no kuv tau sau tseg yuav ua li cas coj lub cuab yeej sib nrug, yog li kuv xav tias kuv yuav zoo ib yam tso rau ntawm no yog tias koj tab tom npaj hloov lub teeb pom kev, koj yuav xav tau ob 3mm puag ncig (lossis tiaj / smd) LEDs uas yuav ci ntsa iab ntawm 1.95V. Thaum etrex sib nrug thiab muab nws rov ua ke dua yog qhov yooj yim xav tsis thoob, tab sis mob me ntsis. Saib kuv tam sim no, koj tsis tuaj yeem qhia nws tau sib nrug.
Kauj Ruam 1: Dissassembly - Ntu 1
Tshem lub roj teeb npog thiab roj teeb. Tshem cov roj hmab puag ncig los ntawm rub. Nws tau daig nrog kua nplaum. Pib nyob rau sab saum toj qhov twg cov txuas txuas yog. Tsis txhob rub hnyav, nws yog ib daig. Muab nws tso rau ib sab kom ntseeg tau tias koj tsis muaj dab tsi nyam ntawm cov kua nplaum, koj tuaj yeem txuas nws dua li nws yog thaum koj ua tiav.
Kauj Ruam 2: Dissassembly - Ntu 2
Sab saum toj thiab hauv qab ntawm rooj plaub raug kaw los ntawm ob txheej kab xev. Thawj txheej pib thiab ua tiav hauv qab ntawm lub cuab yeej. Siv rab riam me me los rub qhov kawg thiab tev nws tawm. Kuv tau kaw daim kab xev ntawm qhov kawg ntawm kuv lub rooj kom nws nyab xeeb thiab yog li nws tsis tuaj yeem lo rau lwm yam. Koj yuav tsum rov siv daim kab xev raws li nws zoo li kom haum rau qhov profile ntawm lub cuab yeej.
Kauj Ruam 3: Dissassembly - Ntu 3
Tshem daim kab xev thib ob. Cov txheej no yog tuab dua thiab tsis zoo li qub. Nws muaj cov kua nplaum zoo dua, tab sis tseem ncab, yog li tsis txhob rub hnyav li koj tev nws tawm. Kev koom tes tau nyob ntawm ib sab ntawm kuv lub cuab yeej. Ib zaug ntxiv, kuv siv rab riam me me los txhawb nqa ntug.
Kauj Ruam 4: Dissassembly - Ntu 4
Nov yog qhov peb qhib rooj plaub. Ob ntu tam sim no tsuas yog ua ke los ntawm cov yeeb yaj kiab. Tsis muaj cov vis dis aus nyob rau sab saum toj ntawm lub cuab yeej yog li kuv pib muaj. Txiav cov ntaub ntawv sib nrug me ntsis rau saum thiab siv rab riam me me, qhib cov kab saum toj kawg nkaus ntawm ib sab ntawm lub cuab yeej. Ua qhov no los ntawm kev tso riam rau hauv lub qhov, tsis yog lub duab plaub. Qhov clip yuav tsum sib nrug tsis muaj kev puas tsuaj. Yog tias nws tsis yog koj yuav zaum tsis siv qhov tsim nyog ntawm kev quab yuam. Kuv tuaj yeem siv lub zog yooj yim nrog kuv cov ntiv tes, tsis xav tau cov cuab yeej ntxiv. Cov yeeb yaj kiab tsuas yog me me, yog li yuav yooj yim rau kev puas tsuaj. Thaum thawj daim clip qhib, qhov seem ua raws nrawm nrog txhua qhov qhib tau yooj yim. Tam sim no rooj plaub yuav tsum sib nrug. Ceev faj, ib nrab nraub qaum txuas nrog PCB ntawm txoj kab txuas txuas ntawm qhov txuas. Tshem qhov txuas.
Kauj Ruam 5: Backlights - Tshooj 1
Cov ntsiab lus ntawm tam sim no LEDs. Left LED: 1.95V +ve ntawm tus pin hauv qabRight LED: 1.95V +ve rau tus pin sab saum toj
Kauj Ruam 6: Backlights - Tshooj 2
Nrog LEDs illuminated.
Kauj Ruam 7: Rov Qab Ua Ke
Reassembly yog ib qho yooj yim heev. Reconnect tus serial cable, snap ob lub halfs rov qab ua ke, ces muab ob txheej ntawm daim kab xev rau, ces cov roj hmab foob. Qhov no yog kuv li tag nrho rov qab ua ke, hmoov tsis tseem nrog tib xim backlights.:(
