Txhim kho ib qho LCD teeb pom kev rov qab nrog lub teeb pom kev zoo ib yam thiab tuag CRT saib xyuas. Lub vijtsam LCD tawg tuaj hauv peb pawg: 1) Lub vaj huam sib luag LCD tawg, ua rau lub tsev tsis muaj nuj nqis 2) Teeb pom kev zoo 3) Teeb meem teeb meem Yog tias nws yog teeb pom kev zoo lossis teeb meem fais fab mov Feem ntau, qhov teeb meem tshwm sim los ntawm qhov hluav taws xob hluav taws xob hloov pauv hloov pauv, xws li lub zog hloov pauv tsis zoo, lub tshuab hluav taws xob, lossis lub zog cua sov ntawm lub rooj tsav xwm hluav taws xob ua rau cov khoom sib tsoo tawg. Cov qij lawv tus kheej muaj qhov txwv lub neej, thiab cov khoom siv hluav taws xob muaj hluav taws xob feem ntau ua rau tsis ua haujlwm. Cov vaj huam sib luag lawv tus kheej yuav luag txhua lub hnub qub thiab cov khoom siv hluav taws xob muaj zog. 17 Dell LCD saib kuv pom yog tsis muaj qhov tshwj xeeb. Thaum kuv xub ntsaws nws, nws yuav hloov lub zog rau thiab tawm tsis tu ncua, nrog rau qhov tsis hnov tsw hlawv. Thaum kuv hloov nws, lub monitor tseem nyob, tab sis lub teeb pom kev yuav flicker rau thiab tawm, thaum kawg kaw tom qab ob peb feeb. tsis tsim nyog nws, tab sis tej zaum kuv tseem tuaj yeem khaws nws, lossis tseem ua kom nws zoo dua. Txawm li cas los koj tuaj yeem hloov pauv yam tsawg kawg yog li qhov no yog qhov tshwm sim ntawm kuv qhov kev sim, nrog kev pab los ntawm tus qub CRT saib:

Kauj Ruam 1: Mus Rau Pov Tseg, Nrhiav Tus Saib Xyuas CRT

Siv lub CRT saib, tshem lub siab thiab muab pov tseg, khaws cia tsuas yog lub plhaub thiab saib xyuas sawv ntsug.

Nruab ib lub teeb qhov (socket) txog 1/2 txoj kev rov qab. Kuv siv hloov lub qhov (socket) los ntawm lub teeb qub. (rau lub teeb, Kuv siv 60w-sib npaug "nruab hnub"/6500k CFL teeb. Nws muaj qhov ci ci rau nws.)

Kauj Ruam 2: Txiav Rov Qab ntawm LCD Saib

Rau LCD saib, txiav tawm nraub qaum thiab tshem cov hlau thaiv/ PCB sab nraum qab ntawm lub vaj huam sib luag, tso lub teeb hla nws.

(Cov kauj ruam no sib txawv ntau ntawm cov khoom lag luam mus rau cov khoom lag luam. Qee lub npe yuav muaj kev sib txuas ntawm ob lub X thiab Y lub dav hlau, thaum qee qhov tsuas yog nyob hauv X dav hlau xwb. txuas tsuas yog ntawm X axis, yog li nqa nws tawm ntawm txoj kev tso cai kom lub teeb hla dhau tau yooj yim, tsis tas yuav tsum muaj kab txuas ntxiv.) nplooj ntawv (ib qho meej, ib qho cuam tshuam, ib qho dawb dawb), thiab tom qab ntawd Plexiglass zoo li lub lim loj. Kuv tshem Plexiglass thiab txhua yam tom qab nws, tsuas yog khaws 3 daim ntawv zoo li cov ntawv tom qab lub LCD. Ua kom pom lub teeb tom qab lub LCD ua rau muaj lub ntsej muag dawb

Kauj ruam 3: Mounting lub LCD

4) Hloov cov laug cam los ntawm LCD vaj huam sib luag mus rau CRT lub plhaub, teeb tsa lub vaj huam sib luag LCD, thiab txuas txhua yam ntxiv. Rau kev txhim kho txhua yam kuv tau siv lub qhov thiab siv cov hlua txuas.

Kauj Ruam 4: Cov txiaj ntsig

Saib kuv qhov project nplooj ntawv rau cov duab ntau ntxiv. Thiab tam sim no yog tias lub teeb puas tawm mus, nws yooj yim hloov. Tsis tas li, raws li qhov tau txais txiaj ntsig, tus saib xyuas lub qhov muag ci, ib nrab pom lub rooj thiab cov keyboard thaum hmo ntuj. Yuav tsum tsis yog txhua tus saib xyuas tau ua li no?:-) Lus Cim LCD Saib yog Dell E172FP. Thaum lub ntsuas saib tawm thiab lub teeb pom kev, cov duab yog pob tshab dua li dub, ua lub teeb/nruab nrab grey. qhov kub me me, tab sis tsis hnyav heev. Muab hom pheej yig hack qhov no yog, nws yog ntau dua qhov lees paub. Tau qhov pom, lub nra hnyav dua li nws tau siv, tab sis lub teeb heev. Yuav luag ib nrab qhov hnyav ntawm LCD saib raws li nws tau ua dhau los. Chav dej chav dej hais tias nws hnyav 7lbs. (thawj LCD qhov hnyav yog 13.25lbs) Tshem tawm ntawm LCD cov hlau thav duab, sawv ntsug, thiab hnyav plexiglass lub teeb lim yog qhov tseem ceeb pab txo qhov hnyav. Qhov CRT lub plhaub thiab lub hauv paus tsuas yog yas (nrog qee qhov springs). me dua li CRT's. Kuv tsuas yog txiav tawm qee daim duab los sau rau qhov khoob kom thaiv lub teeb rau tam sim no. Kuv paub, nws zoo li dab tuag. Tom qab ntawd, kuv yuav ua tus ncej zoo dua.
