Cov hauv qab no yog qee txoj hauv kev los kuaj xyuas LVDS cable ntawm TV:
Kev tshuaj xyuas qhov tshwm sim
- Xyuas seb puas muaj kev puas tsuaj rau lub cevLVDS kabthiab nws cov connectors, xws li seb lub sheath sab nrauv puas puas, seb cov tub ntxhais hlau puas raug, thiab seb cov pins ntawm lub connector yog khoov los yog tawg.
- Txheeb xyuas seb qhov kev sib txuas ntawm lub connector puas ruaj khov thiab seb puas muaj qhov tshwm sim xws li xoob, oxidation lossis corrosion. Koj tuaj yeem maj mam co los yog ntsaws thiab tshem tawm lub connector los txiav txim seb qhov kev sib cuag puas zoo. Yog tias muaj oxidation, koj tuaj yeem so nws nrog dej cawv anhydrous.
Kev ntsuas ntsuas
- Unplug lubTV npo LVDS cablenyob rau sab motherboard thiab ntsuas qhov tsis kam ntawm txhua khub ntawm cov kab teeb liab. Raws li ib txwm muaj, yuav tsum muaj qhov tsis kam ntawm 100 ohms ntawm txhua khub ntawm cov kab teeb liab.
- Ntsuas qhov rwb thaiv tsev tiv thaiv ntawm txhua khub ntawm cov kab teeb liab thiab cov txheej thaiv thaiv. Lub rwb thaiv tsev tiv thaiv yuav tsum loj txaus, txwv tsis pub nws yuav cuam tshuam cov teeb liab kis tau tus mob.
Kev ntsuas hluav taws xob
- Tig lub TV thiab ntsuas qhov voltage ntawm lubLVDS kab.Feem ntau, qhov voltage ib txwm ntawm txhua khub ntawm cov kab teeb liab yog li 1.1V.
- Tshawb xyuas seb qhov hluav taws xob muab hluav taws xob ntawm lub zogLVDS kabyog li qub. Rau cov qauv TV sib txawv, lub zog hluav taws xob hluav taws xob ntawm LVDS tuaj yeem yog 3.3V, 5V lossis 12V, thiab lwm yam. Yog tias lub zog hluav taws xob tsis zoo, nws yuav tsum tau kuaj xyuas lub zog hluav taws xob Circuit Court.
Teeb liab Waveform Test
- Txuas qhov kev sojntsuam ntawm oscilloscope rau cov kab teeb liab ntawm lubLVDS kabthiab saib lub teeb liab waveform. Lub teeb liab LVDS ib txwm yog lub voj voog uas huv thiab meej. Yog hais tias lub waveform yog distorted, lub amplitude yog txawv txav los yog muaj suab nrov cuam tshuam, nws qhia tau hais tias muaj teeb meem nrog lub teeb liab kis tau tus mob, uas tej zaum yuav tshwm sim los ntawm kev puas tsuaj rau lub cable los yog sab nraud cuam tshuam.
Txoj Kev Hloov
- Yog tias koj xav tias muaj teeb meem nrog LVDS cable, koj tuaj yeem hloov nws nrog ib lub cable ntawm tib tus qauv uas paub tias yog qhov zoo. Yog tias qhov txhaum raug tshem tawm tom qab hloov, ces tus thawj cable yog faulty; Yog tias qhov txhaum tseem nyob, nws yuav tsum tau kuaj xyuas lwm yam, xws li logic board thiab motherboard.
