Samsung TVs muaj tus nqi zoo rau nyiaj, yog li ntawd lawv tau txais txiaj ntsig zoo. Txawm li cas los xij, txawm tias tus qauv ntseeg siab qee zaum kuj poob. Yog tias koj tuaj yeem nyeem cov duab kos duab, siv cov khoom siv ntsuas, thiab tuav cov hlau soldering hauv koj txhais tes, sim kho lub TV koj tus kheej.
Cov Lus Qhia
Kauj ruam 1
Ib lub TV niaj hnub no yog cov khoom siv hluav taws xob nyuaj uas tuaj yeem cuam tshuam tau yooj yim yog tias kho tsis raug. Vim li ntawd thiaj ua txhua txoj haujlwm kom zoo, tsis txhob siv lub zog quab yuam. Nco ntsoov tias kev kho cov TVs TV feem ntau cuam tshuam nrog qhov xav tau los kho software, uas nyuaj rau koj ua ntawm koj tus kheej. Yog li ntawd, nyob hauv tsev, nws zoo dua rau koj tus kheej los kho cov TVs nrog tus CRT saib (nrog cathode txoj sab ci raj).

Feem ntau qhov ua tsis zoo ntawm Samsung TVs yog qhov tsis ua haujlwm ntawm lub zog xa hluav taws xob thiab pawg thawj coj ntawm SSB (Central Control Board). Yog tias lub TV qhia tias tsis muaj cov cim ntawm lub neej, ua ntej xyuas lub hwj huam rau lub qhov hluav taws xob. Tom qab ntawv tshem lub thawb hauv TV, xyuas lub pob fais fab thiab lub hwj chim khawm.

Yog tias qhov hluav taws xob txuas hluav taws xob tau tsim nyog rau TV, koj yuav tsum tshawb xyuas lub hwj huam hluav taws xob. Kuaj xyuas nws lub rooj tsavxwm kom zoo, xyuam xim rau txhua qhov cim ntawm qhov cua sov. Raws li txoj cai, cov capacitors hauv lub zog muab hluav taws xob feem ntau swb, cov yuam kev tsis yooj yim los txheeb xyuas los ntawm qhov o saum toj - hauv qhov kev pabcuam nws yog tiaj.
Kauj ruam 4
Yog pom kev pom tsis ua rau muaj kev tsis zoo, tshawb xyuas cov nqi tso tawm. Koj yuav xav tau cov duab kos duab ntawm koj lub TV; nrhiav nws hauv is taws nem. Daim duab piav qhia txhua qhov tso tawm qhov hluav taws xob ntawm lub fais fab. Feem ntau, tsis muaj kab scan ntsuas voltage; nws yuav tsum nyob ib ncig 110-160 volts, nyob ntawm seb qhov loj npaum li cas ntawm lub vijtsam. Qhov loj nws yog, qhov ntau dua qhov voltage.
Kauj ruam 5
Tam sim no koj yuav tsum to taub tias vim li cas tsis muaj cov zis hluav taws xob: qhov fais fab mov yog qhov yuam kev lossis qhov txhaum yuav tsum tau ntsia rau hauv kab ntsuas scan. Kaw lub 110-160 V tso zis hluav taws xob los ntawm lub ntsuas thaij, rau qhov uas koj yuav xav tau txuas ib qho ntawm ib qho ntawm seem ntawm cov hluav taws xob. Tam sim no txuas ib lub teeb pom kev zoo sib xws nrog lub zog hluav taws xob txog 100 watts raws li muaj load. Qhib lub TV thiab ntsuas qhov voltage hla lub teeb. Yog tias nws ze rau qhov qub, lub zog siv hluav taws xob ua haujlwm.
Kauj Ruam 6
Kuaj cov xov kab ua ke. Ua tib zoo saib xyuas kev noj qab haus huv ntawm diodes thiab transistors. Pib sim cov transistor yam tsis unsoldering nws. Nyob rau hauv qhov xwm txheej uas tus simter qhia tau tawg, koj yuav tsum unsolder transistor lossis unsolder tus neeg xyuas pib mus rau nws (nws txaus rau unsolder ob) thiab rov kuaj dua.
Kauj Ruam 7
Tib lub ntsiab cai siv rau diodes ib yam nkaus - unsolder ib qho ntawm cov kev coj ua tsuas yog tias tus ntsuas pom qhov tshwm sim tau tawg. Siv tus taw tes multimeter. Nws yog ntau cov ntaub ntawv tshaj li digital - kev ua haujlwm ntawm qhov chaw tuaj yeem raug txiav txim siab los ntawm qhov degree ntawm deflection ntawm xub, nws muab pov tseg thaum lub sijhawm sib txuas, thiab lwm yam.
Kauj ruam 8
Yog hais tias lub TV tig, tab sis txoj kab nqaim kab rov tav tau pom ntawm qhov screen, qhov ntsuas kev ntsuas kab rov tav yog qhov yuam kev. Txheeb xyuas nws cov ntsiab lus; rau cov microcircuits, them sai sai rau qhov kev sib haum xeeb ntawm cov kev ntsuas ntawm lawv cov haujlwm rau cov uas qhia hauv daim duab.
Kauj Ruam 9
Yog tias LSD TV plam duab, ua rau lub hoob tsaus thiab hloov lub teeb tsom ntawm lub vijtsam. Yog tias koj pom cov duab tsis muaj zog, lub hwj huam hluav taws xob tuaj yeem hloov kho. Tshawb xyuas lub zog lim lub zog; feem ntau lawv yog cov uas swb. Yog tias lawv ua txhaum, nco ntsoov xyuas lub fuse raug ntsia ntawm lub rooj tsav; nws feem ntau hlawv tawm. Hloov qhov chaw tsis zoo thiab qhib TV. Yog tias cov duab tsis pom, lub inverter feem ntau yuav muaj qhov tsis xws luag. Hloov kho cov microcircuit tsis muaj zog.
