Txoj hauv kev zoo tshaj plaws los kho koj lub TV kom zoo yog, ntawm chav kawm, coj nws mus rau ib chav cob qhia. Tab sis yog tias koj txaus siab nyob rau hauv thev naus laus zis thiab muaj kev paub dhau los ntawm qhov ntsuas hluav taws xob siab, ces koj tuaj yeem kho qhov teeb meem koj tus kheej.
Cov Lus Qhia
Kauj ruam 1
Pib los ntawm kev tu koj lub TV. Qhib daim npog sab nram qab ntawm lub rooj plaub thiab siv tus txhuam muag muag thiab lub tshuab nqus tsev tshwj xeeb kom ntxuav cov npoo sab hauv ntawm rooj plaub, daim duab raj thiab lub rooj tsav xwm.
Kauj ruam 2
Ua tib zoo tshuaj xyuas lub rooj tsavxwm thiab cov khoom hauv nws. Yog tias koj pom o lossis tawg ntho lub zog, cov roj tsis muaj zog lossis cov transistors, ces cov teeb meem nyob hauv lawv. Faus cov ntsiab lus no.
Kauj ruam 3
Yog tias koj pom tias daim duab raj tau dhau los ua huab thiab dawb, qhov no txhais tau hais tias tau muaj lub tshuab nqus tsev ploj thiab lub TV tsuas yog tuaj yeem kho tau los ntawm kev hloov lub raj raj duab.
Kauj ruam 4
Yog tias tsis pom qhov puas tsuaj, tshawb xyuas cov haujlwm ntawm lub zog fais fab. Ua ntej tshaj, thim lub load (kab rov tav tsim tawm theem) thiab txuas lub teeb incandescent (txog 100 W) hloov. Yog tias lub teeb cig thiab tawm mus, tom qab ntawd lub hwjchim tau ua haujlwm. Tig nws thiab ntsuas qhov voltage hla lub thau khoom nrog voltmeter. Saib rau ntawm lub rooj tsav xwm seb puas muaj qhov tso zis voltage resistor ze ntawm cov khoom siv fais fab. Qhov voltage yuav tsum tsis txhob siab tshaj 110-150 V. Yog tias qhov hluav taws xob siab dua, kuaj xyuas kev ncaj ncees ntawm cov khoom ntawm thawj pawg ntawm cov ntsuas, nrog rau cov xov xwm tawm tsam. Tshawb cov capacitors, ib yam li lawv muaj peev xwm txo qis dua thaum lawv qhuav.
Kauj ruam 5
Txheeb xyuas qhov txuas hauv kab hluav taws xob tua kab hluav taws xob. Txuas lub teeb incandescent (hloov ntawm lub fuse). Yog hais tias nws flashed thiab tawm mus, txhua yam yog nyob rau hauv kev txiav txim. Yog tias nyob, ua kom cov zis transistor tseem nyob zoo. Yog tias nws nyob rau hauv kev ua haujlwm tau zoo thiab tag nrho cov pulses tam sim no, kuaj kab transformer thiab kab deflecting coils.
Kauj ruam 6
Tshawb xyuas cov kab ntsug (yog tias tsuas yog kab rov tav tau pom ntawm qhov screen). Tshawb xyuas lub zog hluav taws xob ntawm tus tswv oscillator thiab cov theem khoom tsim tawm. Kos lub rectifier diode thiab ntsug scan IC.
Kauj Ruam 7
Kuaj xyuas txhua qhov hluav taws xob sib txuas ntawm CRT. Qee zaum kev so tuaj yeem nyob ntawm tus pin. Siv kub kub hlau ua kom tshem tawm qee qhov epoxy los ntawm cov hlau lead thiab kho qhov qhib, tom qab ntawd rov ntxiv thaj chaw nrog epoxy.
Kauj ruam 8
Txheeb xyuas lub xov tooj cua, vis dis aus video thiab xim thaiv TV. Tshawb cov khoom tswj hwm. Thov nco ntsoov: thaum kho nws, koj yuav tsum siv daim duab lossis cov khoom siv coj los siv, txij li txhua lub TV qauv nws muaj nws cov nuances thaum ua haujlwm. Koj tuaj yeem nrhiav cov ntaub ntawv zoo li no nyob hauv Is Taws Nem.
