Cov saib niaj hnub no yog qhov zoo ntawm cov qauv zoo thiab muaj peev xwm ua haujlwm tau zoo rau ntau dua ib xyoos. Txawm li cas los xij, qee zaum lawv poob. Qhov yooj yim txoj kev yog coj koj tus yuam kev saib mus rau rooj cob qhia, tab sis koj tuaj yeem sim kho nws tus kheej.
Cov Lus Qhia
Kauj ruam 1
Yog hais tias lub ntsuas nrog lub cathode-txoj sab ci tsis ua haujlwm, qhov xwm ntawm kev ua tsis zoo yuav tsum raug ntsuas. Tus saib yuav qhia tsis muaj cov cim ntawm lub neej txhua lub sijhawm, nws yuav qhib, tab sis lub vijtsam tseem nyob tsaus nti. Thaum kawg, duab distortion yuav tshwm sim.

Hauv thawj kis, txheeb xyuas yog tias tus saib xyuas puas tau txais lub zog. Yog tias lub hwj huam qaum tsis ua lag luam, khij lub pob fais fab. Tom ntej no, koj yuav tsum tshawb xyuas lub hwj huam hluav taws xob, rau qhov no koj yuav tsum ntsuas cov hluav taws xob tso tawm nrog cov ntsuas. Lawv yuav tsum sib haum rau cov voltages qhia hauv daim duab Circuit Court. Nrhiav txoj haujlwm hauv Is Taws Nem.
Kauj ruam 3
Thaum tsis muaj qhov hluav taws xob, saib rau qhov tsis ua haujlwm nyob rau hauv ntu qhov ntsuas ntawm lub hwj chim muab hluav taws xob lossis hauv cov neeg siv ntawm qhov hluav taws xob no. Kuaj cov fuses. Hauv cov kuaj niaj hnub no, tsis txhob siv cov fuses nrog ib rooj plaub iav, muaj cov fuse me me uas zoo li MLT-0, 125 resistor. Saib rau lawv qhov chaw raws li daim duab thiab los ntawm cov qauv tsim nyob sab nraum qab ntawm lub rooj tsavxwm.

Yog tias lub ntsuas hluav taws xob nyob, tab sis lub vijtsam tseem tsaus thiab koj tsis hnov cov yam ntxwv tawg uas tshwm sim thaum lub siab hluav taws xob tshwm ntawm qhov hluav taws xob ntawm CRT, kos rau kab kab. Ua tib zoo mloog txog kev sib tiv thaiv ntawm cov ntsuas kev ntsuas kom ntsuas rau cov ntsuas ntawm cov ntsuas ntawm qhov ntsuas.
Kauj ruam 5
Nws yog qhov ua tau tias ib txoj kab rov tav nqaim kab rov tav tau pom hauv nruab nrab ntawm lub vijtsam - qhov no yog lub cim ntawm cov kab uas muaj teeb meem tsis zoo. Yog tias muaj cov duab, tab sis nws yog nqaim heev dhau, qhov ua rau lub teeb tsis sib haum kuj yuav tsum tau saib rau hauv lub vijtsam ntsug. Feem ntau yuav muaj, ib qho ntawm lub capacitors yog xav liam.

Muaj peev xwm ntawm kev kho tus kheej ntawm LCD saib yog nyob ntawm qhov loj ntawm kev tawg. Yog tias cov duab ploj mus, tua lub teeb nyob hauv chav thiab ci teeb tsom ntawm saib ntxiv - koj yuav pom duab tsaus muag heev. Qhov no txhais tau tias backlight tsis ua haujlwm. Qhov feem ntau ua rau muaj kev cuam tshuam zoo li no yog qhov tawg capacitors ntawm lub zog txuas.

Txhawm rau tshem tawm lub ntsuas, hle nws tawm, tshem “ceg”, thiab tso lub vijtsam pw rau ntawm cov ntaub qhwv muag. Txhawm rau qhib rooj plaub, koj xav tau lub cuab yeej tsim nyog: daim npav tsis siv xov tooj, daim yas yas rau kev ntaus kis las, lossis tej yam zoo sib xws. Ntxig cov npoo ntawm daim npav rau hauv qhov sib koom tes ntawm lub sab saum toj thiab hauv qab ntawm cov ntsuas thiab sim cais lawv - lawv tau txuas los ntawm kev sib dhos sab hauv. Txoj hauv qab yuav qhib nrog pob nrov nrov. Tom qab taug kev nyob ib ncig ntawm lub ntsuas ncig ntawm lub ntsuas, cais txhua cov xaim thiab cais cov phiaj.

Tam sim no, ua tib zoo nkag mus rau hauv pawg thawj coj saib, rau qhov no koj yuav xav tau txiav tawm ntau cov txuas txuas thiab txiav tawm cov ntsia hlau. Saib rau lub peev xwm hloov pauv ntawm lub rooj tsavxwm, lawv feem ntau pom meej meej. Hauv kev pabcuam zoo, sab saum toj yog tiaj, hauv qhov tsis zoo, nws o tuaj. Hloov lawv nrog cov tshiab. Nco ntsoov xyuas qhov fuse, thaum lub zog tswj qhov hluav taws xob tawg, nws feem ntau hlawv tawm. Tom qab hloov cov khoom seem, rov qab ntsuas lub ntsuas thiab rov qhib nws yam tsis tau kaw lub khauj qaum.

Yog tias cov duab tshwm, tom qab ntawd txhua yam nyob hauv kev txiav txim thiab tus saib tuaj yeem sib sau ua ke mus txog thaum kawg. Yog tias tsis yog, lub zog inverter microcircuit tuaj yeem raug nplua, thiab lwm yam laj thawj kuj muaj peev xwm ua tau. Hauv qhov no, nws yuav yog qhov tseeb dua los ua tib zoo saib xyuas lub koos pij tawj thiab coj nws mus rau hauv qhov chaw cob qhia - tsis muaj kev paub zoo, nws yuav nyuaj heev kho nws tus kheej Lwm txoj kev, tshawb nrhiav cov lus sib tham online rau cov lus qhia txog cov teeb meem tshwj xeeb rau koj tus qauv ntsuas.
