Idzi dzinotevera dzimwe nzira dzekutarisa LVDS tambo yeTerevhizheni:
Chitarisiko Kuongorora
- Tarisa kana paine kukuvara kwemuviri kuneLVDS tambouye zvinobatanidza zvayo, sekuti sheath yekunze yakuvadzwa, kana waya yepakati yakafumurwa, uye kuti mapini ekotanidzi akabhenda kana kutyoka.
- Tarisa uone kana kubatana kwechibatanidza kwakasimba uye kana paine zviitiko zvakaita sekusununguka, oxidation kana corrosion. Iwe unogona kuzunza zvinyoro nyoro kana plug uye kusunungura chinongedzo kuti utonge kana kubata kwakanaka. Kana pane oxidation, unogona kuipukuta yakachena neanhydrous alcohol.
Resistance Test
- Bvisa iyoTV skrini LVDS tambopadivi rebhodhi reamai uye kuyera kuramba kwepeya yega yega yemitsara yemasaini. Mumamiriro ezvinhu akajairwa, panofanirwa kuve nekupokana kweanosvika zana ohms pakati peyega yega mitsetse yechiratidzo.
-Yeresa kushongedzwa kwekupokana pakati peyega yega yemitsara yechiratidzo uye nhovo yekudzivirira. Kudzivirira kwekudzivirira kunofanirwa kuve kwakakura zvakakwana, zvikasadaro zvinokanganisa kutapurirana kwechiratidzo.
Voltage Test
-Batidza TV uye uyere voltage pairiLVDS tambo.Kazhinji, iyo yakajairwa voltage yepeyi yega yega yemitsara yechiratidzo inenge 1.1V.
- Tarisa kana magetsi emagetsi eiyoLVDS tambozviri normal. Pamhando dzakasiyana dzeTV, magetsi emagetsi eLVDS anogona kunge ari 3.3V, 5V kana 12V, nezvimwewo.
Signal Waveform Test
- Batanidza probe yeoscilloscope kune mitsetse yechiratidzo cheLVDS tambouye tarisa chiratidzo che waveform. Yakajairika LVDS chiratidzo ishasha uye rakajeka rectangular wave. Kana iyo waveform yakakanganiswa, iyo amplitude haina kujairika kana pane ruzha kupindira, zvinoratidza kuti pane dambudziko rekufambiswa kwechiratidzo, izvo zvinogona kukonzerwa nekukuvadzwa kwetambo kana kupindira kwekunze.
Replacement Method
- Kana iwe uchifungidzira kuti pane dambudziko neLVDS tambo, unogona kuitsiva netambo yemhando imwechete inozivikanwa kuti iri mumamiriro akanaka. Kana kukanganisa kuchibviswa mushure mekutsiviwa, ipapo tambo yepakutanga yakashata; kana kukanganisa kwasara, zvinodikanwa kutarisa zvimwe zvikamu, senge logic board uye mamaboard.
