Pehea e nānā ai i ke kelepona LVDS Cable?

Eia kekahi mau ala no ka nānā ʻana i ke kaula LVDS o kahi Televise:

Nānā Hiʻona

- E nānā inā loaʻa kekahi pōʻino kino i kaLVDS uweaa me kona mau mea hookui, e like me ka poino o ka pahu owaho, ina paha i ikeia ka uwea kumu, a ina ua piko a naha paha na pine o ka mea hookui.

- E nānā inā paʻa ka pilina o ka mea hoʻohui a inā he mau mea like ʻole e like me ka looseness, oxidation a i ʻole corrosion. Hiki iā ʻoe ke hoʻoluliluli mālie a hoʻopili a wehe i ka mea hoʻohui e hoʻoholo ai inā maikaʻi ka pilina. Inā he oxidation, hiki iā ʻoe ke holoi maʻemaʻe me ka waiʻona anhydrous.

Hōʻike Kūʻē

- Wehe i ke kaulaUea TV LVDSma ka ʻaoʻao motherboard a ana i ke kūʻē o kēlā me kēia laina laina hōʻailona. Ma lalo o nā kūlana maʻamau, pono ke kū'ē ma kahi o 100 ohms ma waena o kēlā me kēia laina laina.

- E ana i ka pale pale ma waena o kēlā me kēia laina laina hōʻailona a me ka papa pale. Pono ka nui o ka pale insulation, inā ʻaʻole ia e pili i ka lawe ʻana i ka hōʻailona.

Ho'āʻo Voltage

- E ho'ā i ka TV a ana i ka volta ma kaLVDS uwea.ʻO ka maʻamau, ʻo ka volta maʻamau o kēlā me kēia laina hōʻailona ma kahi o 1.1V.

- E nānā i ka mana o ka mana o kaLVDS uweahe mea maʻamau. No nā hiʻohiʻona TV like ʻole, ʻo 3.3V, 5V a i ʻole 12V paha ka mana o ka mana o ka LVDS, a me nā mea ʻē aʻe.

Hōʻoiaʻiʻo Waveform

- Hoʻohui i ka ʻimi o ka oscilloscope i nā laina hōʻailona o kaLVDS uweaa nānā i ke ʻano nalu hōʻailona. ʻO kahi hōʻailona LVDS maʻamau he hawewe maʻemaʻe a maopopo. Inā hoʻololi ʻia ke ʻano hawewe, ʻano ʻino ka amplitude a i ʻole ke kani ʻana o ka walaʻau, e hōʻike ana he pilikia me ka hoʻouna ʻana i ka hōʻailona, ​​ʻo ia paha ke kumu o ka pōʻino i ke kaula a i ʻole ke keakea o waho.

 Keʻano hoʻololi

- Inā manaʻo ʻoe aia kahi pilikia me ke kaula LVDS, hiki iā ʻoe ke hoʻololi iā ia me kahi kaula o ke ʻano hoʻohālike i ʻike ʻia i ke kūlana maikaʻi. Inā hoʻopau ʻia ka hewa ma hope o ka hoʻololi ʻana, a laila hewa ke kaula kumu; inā mau ka hewa, pono e nānā i nā mea ʻē aʻe, e like me ka logic board a me ka motherboard.
