Hauv cov lus qhia no kuv yuav taug kev koj los ntawm kev kho lub lcd tuag rov qab lub teeb hluav taws xob inverter siv cov khoom koj muaj. Koj tuaj yeem qhia yog tias koj muaj lub teeb rov qab tuag los ntawm thawj qhov tshem tawm lwm txoj hauv kev. Txheeb xyuas ntawm ntau lub khoos phis tawj. Xyuas kom tseeb tias lub teeb pom kev ntawm lub ntsuas hluav taws xob qhib thiab nyob twj ywm thiab lwm yam. Rau qhov kev saib xyuas qhov teeb meem raug ua ob lub capacitors raug ntaus nrog "tus kab mob plague" - (saib nws ntawm Wikipedia). thiab qhov kub hnyiab Mount mount resistor. Kuv muab txhua qhov los ntawm cov khoom pov tseg kuv yuav pov tawm. Qhov no yog kho dawb. Kuj yuav tsum ceev faj thaum ua haujlwm nrog cov capacitors thiab cov inverter no feem ntau. Nws yog qhov tshwj xeeb tshaj qhov siab thiab muaj peev xwm o muab qhov poob siab heev. Kuj txhawm rau txuas lub fuse zoo li kuv tau ua - tsis ntse heev. Kev tsim khoom yog qhov pheej yig tiag tiag - yog li yog tias lawv cuam tshuam rau muab lub fuse rau hauv cov khoom lag luam - nws tej zaum yog vim li cas thiaj zoo. Tsuas yog lub koob yees duab uas kuv muaj yog kuv lub iphone - uas tsis zoo thiab kuv thov txim. Vam tias koj tseem tuaj yeem tau txais cov ntsiab lus. Kuv vam tias qhov no yuav pab qee tus. Cov laug cam tshiab hloov pauv txog 65 $ thiab tsis tsim nyog tus nqi. Ntuj raug txim kuv tsuas yog them 180 rau tag nrho cov minitor 3 xyoos dhau los. nyab xeeb ~ txaus siab

Kauj Ruam 1: Ua Pov Thawj Nws Lub Teeb Rov Qab

Ua pov thawj tias koj muaj qhov tuag rov qab: 1. tig lub monitor thaum txuas rau lub khoos phis tawj. 2. nqa lub teeb nyem kom khov thiab ci nws ntawm qhov screen3. saib seb koj puas tuaj yeem ua qhov pom qhov pom ntawm qhov duab. *** nco ntsoov tias lub vijtsam lcd zoo li iav pane. Inorder kom pom cov duab - yuav tsum muaj lub teeb ci los ua kom pom kev.

Kauj Ruam 2: Rub Tus Saib Xyuas Sib nrug

disassemble lub saib: Ntawm chav tsev no muaj plaub tus ntsia hlau nyob tom qab thiab tabs. Rub cov ntsia hlau thiab tshem qhov sib nrug. Tsis txhob ua neeg vwm nkees - koj tsis tas yuav siv tus ntsia hlau tsav los hloov qhov khoom. Hloov maj mam ua haujlwm ib puag ncig perimiter nrog koj cov rau tes. Kuv muaj peev xwm siv daim ntawv thim rov qab ua cov npoo. Qhov no ua haujlwm zoo tiag tiag. Ua haujlwm ntawm nws koj yuav tau txais nws. TSIS TXHOB SIV SCREW DRIVER. koj tuaj yeem ua nws nrog tawm marring li cov yas!

Kauj Ruam 3: Mus rau Electronics

thaum cov yas npog raug tshem tawm tom qab - rub tawm cov hlau sheilding. Hauv qab qhov sheilding yuav zoo li yuav muaj ob lub laug cam. Ib ntawm lawv yuav yog lub logic board thiab lwm qhov yuav yog inverter. Lub logic board yuav muaj tus saib tsis pom - lub inverter yuav muaj cov xov hlau coj mus rau lub teeb tom qab. Feem ntau cov xov hlau yuav xiav/liab.

Kauj Ruam 4: Saib Qhov Tsis Zoo

Ntawm lub rooj tsav xwm inverter saib kom pom kev puas tsuaj. Cov kab mob hlawv - cov khoom tawg lossis hauv kuv cov ntaub ntawv thav duab capacitors. Kuv lub capacitors tau ua tiav.

Kauj Ruam 5: Khaws Khaws Cia

Cov khoom siv hluav taws xob tsis ua haujlwm los ntawm "khawv koob". Thaum qee qhov tawg lawm muaj qhov laj thawj. 99% ntawm cov khoom siv hluav taws xob uas raug pov tseg tuaj yeem kho tau lossis tsawg kawg muaj qee yam khoom zoo. Lob tus qub vcr lossis tv lossis txawm tias mus rau hauv craigslsit thiab tuav lub qub saib. Nrhiav daim uas koj ploj lawm thiab hloov nws. Hauv kuv qhov xwm txheej capacitors tau tuag lawm. lawv tau thab plaub thiab pom tseeb messed. Lawv yog 25v@100uF. Feem ntau (thiab kuv tsis yog kws tshaj lij hluav taws xob - kuv yeej yog tus kws siv tshuab hluav taws xob) hauv cov xwm txheej uas cov khoom siv hluav taws xob tau siv nruj me ntsis hauv lub zog hluav taws xob zam - nws yog qhov ua tau kom nce lub peev xwm. Ntawm no kuv ntseeg tias lub tshuab hluav taws xob tau siv los ruaj khov tawm tam sim no thiab ncaws tawm lub raj. Los ntawm kev nce lub peev xwm qee zaum koj tab tom tso ntau zog ntawm lub zog xa khoom uas yuav tsum ua kom lub hau npog tawm - tab sis feem ntau tsim khoom nyob rau ntawd tsis muaj qhov kawg nrhiav kom txiav tus nqi, tso qhov tsawg kawg ntawm txhua yam hauv lawv cov khoom. Yog li qee zaum nws tuaj yeem nce lub peev xwm ntawm lub hau thiab txhim kho chav tsev. (siv kev nce RAM capacitors ntawm lub computer motherboards) Cov kab lus Wikipedia ntawm kab mob plague yog qhov nthuav heev (rau txhua tus) - nyeem nws. Kuv tau tshwm sim kom muaj lub zog qub dell tso rau ib puag ncig thiab kuv coj cov tiaj ua si los ntawm nws. Koj tuaj yeem tau txais ib feem los ntawm ib qho twg !!!! Kuv pom 25volt capacitors hauv lub zog xa khoom nrog 330uF capacitance. Kuv paub kuv paub,> 3x lub peev xwm? zoo nws ua haujlwm…

Kauj Ruam 6: De-solder & Re-solder

Tawm nrog qhov qub thiab nrog rau qhov tshiab! Solder deb! Nco ntsoov cov khoom siv tam sim no feem ntau yog cov lus qhia! (phim cov kab txaij dub ntawm lub hau kom cim rau ntawm lub rooj tsavxwm)

Kauj Ruam 7: Nws Dose Tsis Ua Haujlwm ?

Hauv cov kauj ruam no kuv muab txhua yam rov los ua ke thiab rub nws hauv. Tsis muaj dab tsi. Nws yuav yog dab tsi? Turnsout muaj ib tug nto mount fuse. los ntawm qhov kuv tau nyeem online SMD fuses account rau 90% ntawm inverter board ua tsis tiav. Kuv nyeem qhov no ntawm lub rooj sab laj yog li kuv tsis paub yog tias nws yog qhov tseeb. Ua siab ncaj Kuv tsis muaj lub tswv yim cov no txawm muaj. Nyob rau ntawm lub inverterboard SMD fuse tau sau lo lus 'R1 "… Resistor 1? Tsuas yog kos rau ntawm lub fuse no yog tsab ntawv" P "lossis tej zaum cov ntaub ntawv qis dua" d ". Txawm li cas los xij kuv tau tshawb thiab tshawb tab sis nrhiav tsis tau amp tus nqi ntawm qhov fuse no.

Kauj Ruam 8: Choj Fuse (Ntawm Koj Tus Kheej RISK)

Kuv poob siab nrog kev sim nrhiav tus nqi ntawm fuse-cov khoom ntim saum npoo tsis tau sau tseg zoo-yog li kuv tau ua dab tsi ib tus kheej hwm "tau-nws-ua-rau-pheej yig" hacker yuav ua. Kuv txuas tus txiv neej nrog ib co xaim. Txog kuv qhov kev tiv thaiv - xaim kuv tau siv yog me me heev awg. Tej zaum cov tuab ntawm cov plaub hau. Thiab kuv yog vim li cas thawj qhov ua rau fuse tsis ua tiav yog qhov tseeb tias cov neeg siv hluav taws xob - ntawm lawv txoj kev tawm mus tau poob peev xwm thiab ua rau cov duab ntau dua tam sim no los ntawm lawv qhov chaw. -(qhov tsis txaus ntseeg tiag tiag ua rau kuv paub). Koj yuav tsum siv lub fuse tiag tiag. Kuv yuav kwv yees tias lub fuse nyob hauv 300mili amp ntau - tab sis qhov no tsuas yog kwv yees

Kauj Ruam 9: Muab Nws Ua Ke thiab Hla Koj Cov Ntiv Tes

muab tag nrho rov qab los ua ke. Tua txhua lub suab nrov sab nraud thiab tso cov khoom siv hluav taws xob nthuav tawm. Thaum koj pulg nws nyob rau hauv tsis hnov tsw rau haus luam yeeb! Mloog seb muaj suab nrov li cas. Qhib chav nyob … puas muaj qhov kub hnyiab? Yog tsis yog, ua tiav!
