Cov neeg siv khoom siv LCD feem ntau ntsib teeb meem hauv qee qhov ntawm lub vijtsam. Qhov no cuam tshuam tsis tau tsuas yog TVs thiab saib, tab sis kuj laptops thiab ntsiav tshuaj. Lub tuam txhab ua lag luam ntawm LCD vaj huam sib luag tam sim no yog Samsung, uas tseem tsim lawv los xaj rau lwm lub tuam txhab. Tab sis ntau npaum li cas los ntawm tus nqi ntawm qhov zoo, thiab nws tsis yog qhov tsis yooj yim rau kev tshuaj xyuas los qhia txog qhov tsaus nti ntawm Samsung LCD TV screen. Nyob rau hauv kev ncaj ncees, nws yuav tsum tau muab sau tseg hais tias xws li artifacts muaj peev xwm nrhiav tau nyob rau hauv cov khoom ntawm yuav luag txhua yam hom thiab nqi ntu.
Dub me ntsis los ntawm kev cuam tshuam
Ntxiv rau qhov kev tsim khoom tsis raug thiab cuam tshuam ntawm cov khoom siv tsis zoo, muaj cov xwm txheej tsaus nti ntawm cov zaub vim yog cov khoom siv tshuabkev puas tsuaj. Xws li qhov tsis xws luag zoo li dub tag nrog cov npoo ntshiab thiab cov kab nrib pleb. Tom qab qee lub sijhawm, qhov muag plooj tuaj yeem tshwm sim. Qhov no yog qhov tshwm sim ntawm overheating ntawm cov pixels uas nyob ib sab. Nyob rau hauv cov ntaub ntawv no, tsuas muaj ib tug tswv yim - hloov lub matrix. Vim lub thinness ntawm lub LCD vaj huam sib luag, nws muaj ib tug tsis tshua muaj kev ruaj ntseg, thiab nws hloov tau yooj yim dua, pheej yig dua thiab sai dua. Tsis tas li ntawd, txoj kev no yuav pab daws qhov teeb meem ntawm qhov tsaus nti ntawm lub vijtsam LCD TV ntawm lub hauv paus.
Kev poob rau hauv keeb kwm dawb
Tsis sib luag dawb glow ntawm matrix yog ib qho cim qhia tias lub dav hlau ntawm ib lossis ntau txheej sab hauv tawg lossis lawv lub siab tsis sib xws. Feem ntau qhov no tsis tshwm sim tam sim tom qab yuav khoom, tab sis tom qab qee lub sijhawm. Tseeb tiag, vim qhov tsis zoo ntawm cov ntaub ntawv los yog kev sib dhos, nyob rau hauv qhov kev txiav txim ntawm cov cua sov, kev ua txhaum ntawm lub geometry ntawm ib feem tshwm sim.
Tsis tas li, vim kev tiv thaiv tsis zoo ntawm cov txheej, hmoov av tuaj yeem nkag mus rau hauv matrix. Raws li lub vaj huam sib luag cua sov thiab txias, nws nthuav thiab cog lus, raws li. Nws zoo li lub twj tso kua mis, nws tuaj yeem nqus plua plav rau hauv nws tus kheej.
Los ntawm qhov kev xav ntawm cov tuam txhab, xws li "qhov mob" tuaj yeem piav qhia los ntawm kev xav kom txo tus nqi thiab ua kom yooj yim rau kev tsim thiab cov khoom siv. Thiab koj tuaj yeem kho nws nrog kev tshem tawm yooj yim. Tab sis nws yuav tsum tau ua tib zoo ua kom zoo li sai tau, vim tias muaj qhov dents lossis khawb ntawm lub vaj huam sib luag tsis tuaj yeem raug tshem tawm.
Matrices nrog kev sib yuav zoo sib xws tau txais los ntawm cov chaw pabcuam rau kev hloov pauv yam tsis muaj teeb meemqhov tsis xws luag nyob rau hauv warranty. Tsis tas li, cov neeg tsim khoom tuaj yeem ua cov phiaj xwm rov qab thaum cov khoom siv tsis zoo raug teeb tsa ntawm tag nrho cov khoom siv. Los ntawm txoj kev, qhov pom ntawm qhov tsaus nti ntawm cov ntxaij vab tshaus ntawm LG LCD TVs kuj tsis yog qhov tsis tshua muaj. Hauv kev tsim cov khoom lag luam rau lwm cov tuam txhab, qee qhov yuav luag sib npaug nrog Samsung.
Yog tias qhov chaw tsaus nti tshwm rau ntawm lub vijtsam LCD TV, qhov no kuj yog vim cov kua tau txais ntawm cov txheej txheem ntawm matrix. Outwardly, lawv yuav luag zoo tib yam nrog plua plav me ntsis. Yog li ntawd, txhawm rau txheeb xyuas tus kheej ntawm qhov ua tsis tau zoo, koj yuav tsum xav txog qhov twg thiab cov dej noo nkag mus rau hauv TV lossis lwm yam zaub.
Txoj kev xav, qhov teeb meem no tuaj yeem daws tau los ntawm disassembling lub matrix thiab ntxuav lub polarizer thiab diffuser. Ntawm chav kawm, kev ntxuav yuav tsum tsis txhob nqa nrog dej kais dej, vim tias tom qab ziab yuav muaj stains los ntawm cov ntsev thiab cov deposits. Cov dej ntshiab huv los yog cov cawv ntshiab huv yog qhov tsim nyog rau qhov no.
Tab sis nws tseem zoo dua rau kev tso siab rau cov txheej txheem no rau cov kws tshaj lij uas tsim nyog, txij li thaum lub sij hawm disassembly los yog sib sau ua ke ntawm matrix, irreparable puas tsuaj rau lub cuab yeej tuaj yeem tshwm sim. Yog tias koj txiav txim siab ua koj tus kheej, ces disassembly thiab sib dhos yuav tsum tau nqa tawm hauv chav huv, nyiam dua tom qab ntxuav kom ntub, kom cov plua plav tsis ya hauv huab cua. Cov hnab looj tes yuav tsum tau hnav kom tsis txhob tso cov ntiv tes tawm ntawm cov khoom siv matrix.
Tseeb hauv kaum lossis ib puag ncig
tsaus nti ntawm lub vijtsam LCDTVs tej zaum yuav muaj ntau lub hauv paus chiv keeb, thiab tus nqi, nrog rau kev kho, yuav txawv. Yog hais tias tsaus nti oval los yog puag ncig stains tshwm nyob ib ncig ntawm lub perimeter los yog nyob rau hauv lub ces kaum ntawm lub screen, ces, feem ntau yuav, ib feem ntawm lub matrix LED backlight ua tsis tau tejyam. Qhov kev tsis zoo no feem ntau pom hauv TVs thiab saib xyuas los ntawm Suav tuam txhab lag luam hauv cov nqi peev txheej. Xws li kev tawg yooj yim tshem tawm los ntawm kev hloov cov diodes hlawv. Qee qhov xwm txheej, soldering lub teeb pom kev sib cuag tuaj yeem pab tau.
khib nyiab hauv matrix
Nws tshwm sim thaum lub caij tsheb thauj mus los lossis thaum lub sijhawm sib sau ua ke ntawm TV, plua plav thiab ntau cov khib nyiab me me tau nruab nrab ntawm cov txheej txheem ntawm matrix. Ntawm cov rooj sib tham thematic, qhov xwm txheej tau piav qhia thaum yoov tig los ua qhov tsaus ntuj ntawm qhov screen ntawm Samsung LCD TV, uas nyuam qhuav raug coj los ntawm lub khw.

Thiab lub tuam txhab tsis muaj lub luag haujlwm yog tias cov khoom txawv teb chaws tau los ntawm lawv. Cov neeg siv ntawm lub rooj sab laj qhia tapping rau ntawm ob sab ntawm lub saib raws li kev daws teeb meem no txhawm rau txhawm rau me ntsis thawb cov khaubncaws sab nraud povtseg ntawm cov zaub sib nrug thiab cia cov plua plav poob, lossis maj mam coj mus rhaub cov saib nrog daim ntaub tuab, zoo li knocking. tawm” nws. Tab sis tsis txhob dhau mus dhau ntawm txoj kev no, thiaj li tsis ua rau muaj kev puas tsuaj uas tau piav qhia hauv thawj kab lus.
Yog li ntawd, yuav ua li cas yog qhov chaw tsaus ntiPuas yog koj lub vijtsam LCD TV tiv thaiv koj los ntawm kev txaus siab rau daim duab?

- Nqe dej noo. Tawm ntawm cov ntaub ntawv lav thawj zaug, tab sis yaug tib yam li cov plua plav nkag tuaj yeem pab tau.
- Ua tsis tiav ntawm cov teeb ci LEDs. Cov ntaub ntawv tau lees paub yog tias tsis muaj cov cim qhia ntawm qhov qhib ntawm rooj plaub. Yog tias lub warranty tau tas sij hawm, koj tuaj yeem hloov cov diodes hlawv lossis tag nrho daim kab xev.
- khib nyiab ntawm txheej. Nyob rau hauv qhov tsis muaj cov cim ntawm qhov qhib, qhov no yog rooj plaub warranty. Tab sis koj tuaj yeem tshem tawm koj tus kheej los ntawm tshuab matrix.
Kuv xav hais tias tsab xov xwm no yog lus qhia. Yog tias qhov tsaus nti tshwm sim ntawm lub vijtsam LCD TV, nws yog qhov zoo tshaj rau hu rau cov kws tshaj lij.
