1. Qee cov khoom siv hluav taws xob muaj cov khoom siv hluav taws xob uas tsis raug cais tawm ntawm 220V AC fais fab mov, ua rau cov dej xau. Qhov no feem ntau tshwm sim nrog cov khoom qub, xws li qee lub TVs xim, qhov twg kov lub kav hlau txais xov tuaj yeem ua rau muaj qhov tsis hnov tsw. Txawm hais tias cov me me tam sim no feem ntau tsis txaus ntshai, lawv tshwm sim vim muaj kev tiv thaiv loj ntawm lub rooj tsav xwm hauv Circuit Court thiab cov khoom siv hluav taws xob, ua rau muaj qhov xau tsawg heev.
2. Txawm hais tias lub rooj tsav xwm hauv Circuit Court nws tus kheej tsis muaj teeb meem, qhov xau tseem tuaj yeem tshwm sim vim yog cov khoom tsis zoo (tshwj xeeb tshaj yog cov capacitors) los yog vim muaj dej noo thiab plua plav tsub zuj zuj ntawm lub rooj tsav xwm Circuit Court. Piv txwv li, qee cov khoom siv yuav tsis pom muaj qhov xau thaum pib tab sis yuav pib xau tom qab siv lub sijhawm. Qhov no feem ntau yog cov ntaub ntawv nrog cov khoom siv uas tsis yog hauv av.
Yuav Tiv Thaiv Lub Hwj Huam Li Cas
1. Txoj hauv kev yooj yim tshaj plaws yog hloov cov haujlwm ntawm cov hluav taws xob thiab xoom kab (piv txwv li, tig ob-theem ntsaws ntsaws 180 degrees thiab muab tso rau hauv lub qhov (socket). Txoj kev no feem ntau siv tau zoo, vim qee cov khoom siv yuav tsum ua raws li "sab laug xoom txoj cai hluav taws" txoj cai. Swapping lub plug txoj hauj lwm yuav tshem tawm lub plhaub to. Qhov no yog qhov tseem ceeb tshwj xeeb rau cov khoos phis tawj thiab cov tshuab luam ntawv, uas yuav tsum nruj me ntsis ua raws li txoj cai no. Kuv tus kheej tau ntsib cov xwm txheej uas lub khoos phis tawj thiab cov tshuab luam ntawv tau hluav taws xob thaum ntsaws rau hauv qhov tsis ncaj ncees lawm, ua rau nws tsis muaj kev nyab xeeb rau kov cov hlau casing. Siv lub cwj mem hluav taws xob lossis multimeter, kuv pom tias qhov hluav taws xob ntawm lub cuab yeej thiab hauv av mus txog 160 volts. Swapping lub firewire thiab xoom txoj hauj lwm daws qhov teeb meem.
2. Ntxuav cov plua plav tawm ntawm lub rooj tsav xwm Circuit Court, tshwj xeeb tshaj yog cov khoom siv hluav taws xob motherboard. Plua plav, tshwj xeeb tshaj yog thaum damp, qee zaum tuaj yeem ua cov khoom siv hluav taws xob thiab ua rau lub siab-voltage thiab qis-siab qhov chaw ntawm lub plhaub kom them. Kev tu lub rooj tsav xwm hauv Circuit Court plua plav tuaj yeem tiv thaiv qhov teeb meem no. Yog tias cov plua plav tsis yooj yim tshem tawm lossis tau nqus dej noo, ntxuav nws nrog dej cawv tsis muaj dej thiab tom qab ntawd ziab nws siv lub tshuab ziab khaub ncaws.
3. Yog tias cov txheej txheem saum toj no tsis ua haujlwm, qhov kev daws teeb meem zoo tshaj plaws yog kev siv cov khoom siv lub plhaub. Los ntawm kev siv hluav taws xob hauv av, tib neeg yuav tsis raug hluav taws xob poob.
