Samsung LCD TV ntawm Qhov Teeb Meem DIY Kho Kho: 5 Kauj Ruam (nrog Duab)

2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:26

Peb muaj Samsung 32 LCD TV mus rau fritz tsis ntev los no. Lub TV yuav qhib, tom qab ntawd tig nws tus kheej tam sim ntawd, tom qab ntawd qhib dua … hauv qhov tsis muaj qhov xaus. Tom qab ua kev tshawb fawb me ntsis, peb pom tias muaj rov qab los ntawm cov TV no vim ua tsis tau zoo capacitors siv thaum tsim khoom.

Peb kuj tau tshawb pom qhov rov nco tau xaus ob peb xyoos dhau los

Tsis xav yuav TV tshiab lossis them nyiaj kwv yees $ 150 kom kho nws, Kuv tau tuav kuv cov hlau txuas uas ntseeg siab thiab mus ua haujlwm. Nws hloov tawm tias tsuas yog $ 3- $ 6 hauv ntu, koj tuaj yeem kho qhov teeb meem no koj tus kheej. Tsuas yog cov txuj ci nws yuav siv yog qee qhov kev siv yooj yim thiab cov txheej txheem desoldering. Nov yog ob peb ntawm Cov Ntawv Qhia Zoo tshaj sau los ntawm lwm tus kws sau piav qhia cov txuj ci no:

• Yuav Siv Li Cas
• 9 Txawv Desoldering Cov Qauv

Tam sim no rau cov ntaub ntawv …

Ua raws kuv ntawm Instagram - @therealcoffeedude

Kauj ruam 1: Cov ntaub ntawv

Ua qhov kev kho no (tsis yog lub TV LCD tsis raug), koj yuav xav tau*:

• Soldering Hlau
• Desoldering Braid ** lossis De-solder Vacuum Pump
• Solder
• Dej ntws
• Hloov lub capacitor (ntau ntxiv txog qhov no tom qab)
• Ib Phillips Screwdriver
• Hlau Clippers
• Tes Pab (xaiv tau)

*Cov kab ntawv txuas rau cov khoom tshwj xeeb uas kuv tau siv.

** Ua rau koj tus kheej nyiam thiab nco ntsoov yuav braid lossis wick nrog flux twb muaj lawm hauv nws.

Kauj ruam 2: Disassembly thiab kuaj mob

Yuav luag txhua qhov xwm txheej, qhov teeb meem tshwj xeeb no yog tshwm sim los ntawm ib lossis ntau lub capacitors ntawm lub rooj tsav xwm hluav taws xob dhau cua sov. Nrhiav lub ntsuas hluav taws xob ntau dhau yog qhov yooj yim thaum koj tau txais lub nraub qaum tawm hauv TV. Coj cov duab thaum koj mus hauv qhov xwm txheej koj xav tau xa rov qab mus rau qhov khoom nyob qhov twg, tshwj xeeb yog ntawm pawg thawj coj.

Ua tib zoo tshem lub rooj muag zaub thiab tom qab ntawm TV. Nco ntsoov tias koj muaj lub ntsej muag huv, tiaj tus kom tso lub TV ntawm lub ntsej muag, tom qab ntawd tshem cov khoom sawv tom qab los ntawm cov ntsia hlau dub nyob ib puag ncig sab nraum qab ntawm lub TV. Yog tias tag nrho cov ntsia hlau tau raug tshem tawm, sab nraub qaum yuav tsum tsa thiab tawm, yooj yim heev. Tsis txhob yuam nws.

Pawg tswj fais fab nyob ntawm sab xis. Yog tias koj saib daim duab ntawm lub zog xa hluav taws xob, koj yuav pom qhov ze ntawm qhov hluav taws xob hlawv tawm. Daim ntawv ceeb toom saum toj no tsis tiaj tus, tab sis tau puckered thiab sib cais. Txhawm rau tshem tawm pawg thawj coj saib xyuas hluav taws xob, Ua tib zoo tshem tawm ob txoj hlua txuas mus rau lub rooj tsavxwm (ib qho ntawm sab laug thiab ib qho rau saum). Tom qab ntawd ntswj cov nyiaj ntsia hlau ntawm plaub fab. Yuav muaj cov ntsia hlau ntxiv nyob rau hauv kaum sab laug hauv qab ntawm pawg thawj coj saib qhov twg lub hwj huam qaum ntsaws rau hauv. Qhov no tau sau tseg hauv daim duab. Ua koj tus kheej nyiam thiab ntsia hlau cov ntsia hlau nyiaj rov qab rau hauv lawv lub qhov kom koj tsis txhob xau cov ntsia hlau lossis lawv mus qhov twg.

Tam sim no peb desolder…

Kauj Ruam 3: Tawm Nrog Qhov Tsis Zoo…

Peb nce lub rooj tsavxwm hauv kev pab txhais tes, sau cia qhov twg lub capacitor tsis zoo nyob ntawm sab hauv qab. Tom qab ntawd peb desolder cov kev sib txuas, thiab tshem tawm ib feem. Koj puas tau nco ntsoov nco ntsoov txoj kev twg thiaj tau teeb tsa lub capacitor? Koj puas tau thaij duab? Txoj hauv kev yooj yim kom nco ntsoov txoj kev uas tus capacitor mus yog kom nco ntsoov sab twg txoj kab ntsug tau nyob ntawm. Yog tias koj xav tau kev pab desoldering, tsuas yog tham nrog Cov Ntawv Qhia thaum pib ntawm qhov no.

Tam sim no peb nyob hauv qhov tshiab…

Kauj Ruam 4:… Hauv Nrog Qhov Zoo

Ua kom ntseeg tau tias peb muaj lub ntsuas hluav taws xob tau teeb tsa txoj hauv kev, tam sim no peb tau siv lub tshuab hluav taws xob tshiab. Peb paub tau li cas lub capacitor yuav?

Muaj peb yam tseem ceeb uas txheeb xyuas tus capacitor. Ua ntej, nws muaj peev xwm, thib ob, nws yog qhov hluav taws xob, thiab thib peb, nws yog tus coj. Tej zaum kuj yuav muaj qhov ntsuas kub ib yam nkaus. Rau peb lub capacitor, txhua yam peb xav tau txhawm rau txheeb xyuas qhov hloov pauv kom raug yog qhov muaj peev xwm ua tau zoo hauv micro-Farads (47µF), qhov hluav taws xob ua haujlwm hauv volts (160v), thiab thaum kawg, txij li ob leeg coj tawm hauv qab, qhov no yog lub tshuab hluav taws xob (as opposed to axial lossis snap-in capacitor).

Kuv pom kaum ntawm cov no ntawm Amazon rau 15 bucks. Qhov ntawd yog $ 1.50 txhawm rau kho lub TV, tsis zoo li them $ 150. Kuv tsis mloog yuav 9 lub capacitors ntxiv, vim tias muaj ib hnub kuv yuav pom siv rau lawv.

Tam sim no peb muab nws tag nrho rov qab ua ke txoj cai?

Kauj Ruam 5: Xeem Ua Ntej, Tom Qab Sib Sau

Hloov lub rooj tsav xwm hluav taws xob hauv TV (tsis yog koj zoo siab koj tsis plam cov ntsia hlau?), Ntsaws ob lub xov tooj rov qab rau hauv, thiab tom qab ntawd ntsaws TV rau hauv thiab txheeb xyuas nws tam sim no ua haujlwm. Yog tias nws tsis yog, koj puas tau muab lub tshuab hluav taws xob tso rau hauv txoj kev yog (+/-)? Puas muaj ntau dua ib lub tshuab hluav taws xob hlawv tawm uas koj tau ploj lawm?

Yog tias koj tau txheeb xyuas tias lub TV ua haujlwm tau zoo, hloov lub nraub qaum thiab sawv ntsug thiab tom qab ntawd txaus siab rau cov txiv hmab txiv ntoo (thiab txuag nyiaj) ntawm koj txoj haujlwm!
