Vim li cas lub TV puv tua yog cov lus nug nquag ntawm cov neeg siv TVs los ntawm cov chaw tsim khoom sib txawv. Nws tuaj yeem muaj ob qho laj thawj rau qhov no, thiab xws li qhov tsis sib xws yog tshem tau.
1. Qhov chaw tsis muaj tseeb. Qee lub TVs laus muaj Lub Auto Power Off muaj nuj nqi hauv cov ntawv qhia zaub mov. Yog tias tsis muaj lub cim txais tos rau lub sijhawm ntev, TV tso tawm. Thov nco ntsoov yog tias qhov tshwj xeeb no tau qheb lossis tsis, kaw lub hwj chim tua nws tus kheej thiab koj yuav ua zoo. Malfunction. Yog tias lub TV tshiab thiab tseem nyob hauv qhov kev pabcuam warranty, tom qab ntawv qhov no nws yog qhov yuav tsum tau hu rau lub chaw pabcuam tshwjxeeb kom kho. Thaum lub sijhawm tag sijhawm ntawm lub sijhawm lav, koj tuaj yeem tiv tauj txhua lub khw muag khoom siv rau cov khoom vaj khoom tsev, tshwj xeeb nrog rau cov neeg ua haujlwm tsim nyog. Ntawm no koj muaj cai tau txais kev lav lav kho-lav kev lav paub nyob rau qee lub sijhawm. Qhov chaw ib puag ncig hauv TV ua haujlwm yog qhov tseem ceeb. Qhov kub thiab txias, av noo, plua plav ib puag ncig, cuam tshuam ib puag ncig cuam tshuam kev ua haujlwm ntawm Circuit Court Cheebtsam, oxidation thiab kev puas tsuaj ntawm cov neeg sib cuag, overheating tshwm sim, uas thaum kawg ua rau qhov tshwm sim txuas. Qee lub sij hawm nws txaus los tshuab los ntawm lub TV chassis nrog cov kwj ntawm cov cua kom zoo, hloov cov fuses, thiab so cov neeg oxidized. Tsis tas li, qhov laj thawj yuav ua tau surges thiab voltage poob hauv lub network. Yog koj muaj kev paub hauv xov tooj cua yam xws li tshuab hluav taws xob thiab paub siv hlau soldering thiab tester, ces koj tuaj yeem sim nrhiav qhov laj thawj rau kev tua TV koj tus kheej thiab tshem tawm nws. Ua ntej tshaj plaws, pom kev lub xeev ntawm lub capacitors ntawm lub zog muab khoom. Ntev dhau los, cov xaim hluav taws xob tuaj yeem plam lawv qhov ua tau zoo, ua kom qhuav, o, cov xaim hluav taws xob zoo li pom hauv qab ntawm lub hau, qhov no tuaj yeem pom ntawm qhov chaw ntub ncig lawv. Qee lub sij hawm qhov no yuav xeb tooj liab txuas ntawm ob sab ntawm PCB. Qee qhov xwm txheej, nws txaus los hloov qhov tsis xws luag ntawm capacitor. Sim ua ib qho kev ua tiav qhov kev kuaj pom ntawm cov pob zeb mounting. Ua li no, tso caj npab koj tus kheej nrog lub zog loj dua thiab muab lub teeb pom kev zoo. Thaum lub sijhawm dhau los, vim muaj cua sov, cov kab nrib pleev cov nplhaib tshwm sim hauv cov kab ntawm cov ntawv luam tawm Circuit Court, tsis zoo-soldering ntawm Circuit Court cov ntsiab lus yog qhia. Txhua qhov chaw tsis txaus ntseeg yuav tsum tau ua tib zoo muag, uas feem ntau ua rau kev tshem tawm cov teeb meem ntawm kev raug kaw. Tsis tas li, malfunctions nyob rau hauv kab lossis thav duab scanning tshuab yog ua tau, hloov pauv lossis cov khoom hauv lawv lub voj voog tsis ua haujlwm. Xws li kev puas tsuaj twb nyuaj rau kev txheeb xyuas tus kws paub tshwj xeeb. Koj tuaj yeem thov kev pab hauv Is Taws Nem. Muaj ntau lub vev xaib thiab kev sib tham uas cov kws paub txog kev kho cov cuab yeej hauv TV yuav qhia rau koj cov lus qhia dav dav thiab muab tswv yim. Thov nco ntsoov tias kev kho lub TV yog nyob rau qeb ntawm kev ua haujlwm tshwj xeeb, vim tias muaj qhov ntsuas hluav taws xob ntau ntawm ob peb txhiab volts, thiab tsis muaj cov kev paub thiab kev tsim nyog, koj tso koj lub neej nyob rau qhov txaus ntshai heev. Soberly ntsuam xyuas koj lub peev xwm, thaum tsis ntseeg, ntseeg tus telemasters.
