Niaj hnub no, yuav luag txhua lub tsheb neeg caij tsheb muaj lub tshuab kaw cov xov tooj cua. Lub suab nkauj los ntawm cov neeg hais lus nthuav dav cov kev tsav tsheb tsis tseem ceeb, txhim kho lub siab, pab kom dhau lub sijhawm, tsis tseg hauv kev tsheb. Yog hais tias lub xov tooj cua hauv tsheb tsis tawm, thawj zaug koj yuav tsum txiav txim siab qhov ua rau muaj kev tsis zoo thiab tsuas yog tom qab ntawd npaj mus nrog kev kho.

Cov Lus Qhia
Kauj ruam 1
Yog tias lub tshuab txais hluav taws xob nres, xyuas seb qhov khoom siv hluav taws xob puas yog tam sim no, yog tias fuses, tiv thaiv diodes, sensors thiab stabilizer ua haujlwm. Yog tias koj pom cov khoom tsis raug, kho lossis hloov nws.
Kauj ruam 2
Yog tias lub teeb hluav taws xob rov qab ntawm cov vaj huam sib luag tshem tawm ntawm lub tshuab ntaus suab tsis ua haujlwm, tshawb xyuas qhov kev pabcuam ntawm lub teeb thiab txuas ntxiv ntawm lawv lub zog hluav taws xob hauv Circuit Court, qhov kev cia siab ntawm kev sib txuas ncaj qha hauv cov txuas ntawm lub caij tshem tawm thiab tshem tawm qhov tsis ua haujlwm.
Kauj ruam 3
Thaum lub suab tsis ua dua tshiab nyob hauv txhua hom, qhov tshwm sim tuaj yeem ua rau muaj kev cuam tshuam ntawm microcircuit. Ua ntej tshaj, xyuas qhov voltage ntawm qhov tsim tawm ntawm lub teeb liab audio thiab lwm qhov ntawm Circuit Court. Yog hais tias siv hluav taws xob, tab sis tsis muaj suab nrov, nws yuav tsim nyog ua ntej cov microcircuit. Ua haujlwm nrog hlau tshwj xeeb soldering - kom zoo thiab meej li sai tau. Raug coj los ntawm daim duab nyob hauv phau ntawv rau lub xov tooj cua tsheb.
Kauj ruam 4
Yog tias qhov rhiab ntawm AM tuner tsis tau siab txaus, xyuas qhov kev pabcuam ntawm bandpass lim, diode sib dhos thiab muaj cov teeb liab ntawm cov tswj cov tuner. Muaj qhov tseeb tsim qhov xwm ntawm kev ua tsis zoo, koj tuaj yeem kho lub xov tooj cua hauv tsheb sai. Nrog tus cwj pwm qis ntawm FM tuner, nws yog qhov tseem ceeb ntxiv rau kev soj ntsuam kev noj qab haus huv ntawm cov khoom ntawm cov zis ntawm transistor thiab cov voj voog uas nyob ib sab.
Kauj ruam 5
Yog hais tias cov discs tsis ua si, tom qab qhov tshwm sim tuaj yeem ua rau muaj kev cuam tshuam tsis zoo hauv kev ua haujlwm ntawm lub teeb liab audio hloov mus rau chav tsev lossis chav ua haujlwm. Tab sis ua ntej koj pib soldering lub microcircuits, tshawb xyuas kev ncaj ncees ntawm cov txuas ntawm kev sib txuas ntawm cov CD thiab xov tooj cua, qhov tseeb ntawm qhov txuas no.
