Zoyenera kuchita ngati makanema apawayilesi a digito sakuwonetsa komanso chifukwa chake izi zimachitika

Ubwino ndi kuphweka kwa njira zoulutsira digito zitha kusokonezedwa ndi kulephera kwa zida. Osathamangira kuitana mbuye ndikupereka ndalama. Nthawi zina vutoli limathetsedwa popanda akatswiri.

Ndi mavuto ati omwe amakhudza mawonetsedwe a digito

Mndandanda wamavuto omwe akubwera umaphatikizapo zolephera zomwe zimachitika pafupipafupi zomwe wosuta wachiwiri aliyense amakumana nazo. Kuwulutsa kwapa digito ndi zida zolandirira anthu amapangidwira anthu ambiri, kotero kuti kuwonongeka kwapang’onopang’ono sikuphatikizidwa. Komabe, pali nthawi zina pamene:

• kusaka munjira yodziwikiratu sikunapeze njira imodzi;
• sizili zonse zoulutsidwa m’dera lanu zidapezeka;
• mayendedwe ali ndi zobwereza;
• bokosi la set- top limalumikizidwa , koma menyu sikuwoneka pazenera mutakanikiza kiyi yofananira pa remote control;
• menyu yokhazikitsira pamwamba ili pazenera, koma mukayamba kukhazikitsa, uthenga “Palibe chizindikiro” chikuwonekera;
• palibe chizindikiro, ndipo palibe mapulogalamu omwe amasonyeza;
• autosearch sanapeze kalikonse, uthenga pawindo: “Palibe mautumiki”;
• chithunzicho chimaundana pa chimango chimodzi, chimagwera mu cubes, mawu akuti “chibwibwi”;
• chithunzi chosamveka, chosamveka bwino, kapena palibe;
• wakuda ndi woyera chithunzi pa mtundu TV chophimba.

Chifukwa chiyani sakuwonetsa mayendedwe a digito?

Kulephera, pamene zipangizo sizikulandira ndipo sizikujambula chizindikiro cha digito, zimakhala ndi zifukwa zingapo. Pali zisonyezo zina kuti kukonza, kusintha zida, kapena kutsimikizira kulumikizana kolondola ndikusintha ndikofunikira.

Pofufuza chifukwa chake, chokani chosavuta mpaka chovuta. Kulephera nthawi zina kumadziwika mosavuta, ndipo sikufuna nthawi yochuluka ndi chidziwitso kuti kuthetsedwe. Ngati mwataya chithunzicho, kapena matchanelo sakuwongoleredwa, choyamba, funsani ngati anansi anu, achibale kapena mabwenzi anu okhala m’dera lanu ali ndi wailesi.

Kulephera kwa mlongoti

Kulephera kwa mlongoti ndikosowa . Zifukwa za izi ndi kuwonongeka kwa makina, zotsatira za nyengo (mphezi, chinyezi, mphepo yamphamvu), ngati ili kunja. Kapena kulephera kwa amplifier chizindikiro, ngati alipo.

Mavuto ndi zingwe ndi kulumikizana

Ngati zidazo zalumikizidwa molakwika, zolakwika zotsatirazi ndizofala:

• soketi yolakwika idagwiritsidwa ntchito kulumikiza pulagi;
• bokosi lokhazikitsidwa kunja silikulumikizidwa bwino;
• Zidazi sizimalumikizidwa ndi mains, ndipo zizindikiro zamphamvu pabokosi lokhazikika kapena TV siziyatsa.

Mavuto a Hardware

Kuti mulandire chizindikiro cha digito, mlongoti ndi chochunira chakunja kapena chomangidwa chimafunika. Zolephera zenizeni za zida zonse ndizotheka:

• kulephera kwa console ;
• otsika wolandila firmware , mtundu wachikale wa pulogalamu yosinthira ma sign, firmware sinamalizidwe molondola kapena osamalizidwa;
• mavuto ndi kulandira chizindikiro , – njira yolakwika ya mlongoti kupita ku nsanja yobwerezabwereza, kusokoneza njira yowonetsera (zomangamanga, nduwira zamitengo, mapiri);
• kukonzanso zoikamo, firmware yachikale (yopezeka pa LG TVs);
• ntchito yokonzanso,  kuthetseratu kwadzidzidzi kapena kukonzedwa kwa kuwulutsa ndi opanga ma TV a digito kuti abwezeretsedwe kapena ntchito yokonzedwa.

Mavuto ndi kulandira chizindikiro

Ma frequency a decimeter omwe kuwulutsa kwa digito kumachitika kumafunikira kulowera komwe kulandirira mlongoti kupita ku nsanja yobwereza. Kusokoneza kulikonse panjira yake kumayambitsa kutayika kwa mtundu womwe walandilidwa. Izi zikuphatikizapo:

• Nyengo yoipa . Mvula, mabingu, chipale chofewa, chifunga chimapanga maziko ndikusokoneza kuwulutsa kwa siginecha kuchokera pansanja.
• Zolepheretsa zakuthupi (kusokoneza) polowera chizindikiro.
• Kulandila kwa siginecha kuchokera kunsanja ziwiri kapena zingapo zoyandikana zobwerezabwereza .
