Kev tshuaj xyuas qhov muag
- Tshawb nrhiav qhovkabrau ib qho kev puas tsuaj pom xws li tawg, tawg, lossis khoov tus pins. Xyuas seb cov connectors puas qias neeg los yog corroded.
Kev kuaj teeb liab nrog Multimeter
- Teem lub multimeter mus rau qhov kev tawm tsam lossis kev txuas ntxiv.
- Txuas cov kev sojntsuam mus rau cov pins sib thooj ntawm ob qhov kawg ntawm qhovLVDS kab. Yog hais tias lub cable yog nyob rau hauv zoo, lub multimeter yuav tsum qhia ib tug tsawg kuj los yog continuation, qhia tias cov xov hlau tsis tawg.
Siv lub teeb liab Generator thiab Oscilloscope
- Txuas lub teeb liab lub tshuab hluav taws xob mus rau ib qho kawg ntawm qhovLVDS kab thiab oscilloscope rau lwm qhov kawg.
- Lub teeb liab lub tshuab hluav taws xob xa tawm cov teeb liab tshwj xeeb, thiab oscilloscope yog siv los soj ntsuam cov teeb liab tau txais. Yog tuskabua hauj lwm kom zoo, oscilloscope yuav tsum tso saib ib tug meej thiab ruaj khov teeb liab waveform uas yog raws li cov zis ntawm lub teeb liab generator.
Hauv-Circuit Test
- Yog ua tau, txuas lubLVDS kabmus rau lub TV thiab cov Circuit Court boards. Siv cov ntsiab lus xeem rau ntawm lub rooj tsav xwm Circuit Court los ntsuas qhovLVDSteeb liab. Xyuas seb cov qib voltage thiab cov yam ntxwv ntawm cov teeb liab yog nyob rau hauv ib txwm muaj teev los ntawm TV cov ntaub ntawv qhia.
Yog tias ib qho ntawm cov kev ntsuam xyuas no qhia tias muaj teeb meem nrog rauLVDS kab, tej zaum nws yuav tsum tau muab hloov los xyuas kom meej lub cev ua haujlwm ntawm lub TV.
