Ngamanye amaxesha sifumanisa ukuba asikwazi ukusebenzisa iseti yethu yeTV kwaye ekuphela kwento esiyibonayo kwisikrini ileyibhile ebonisa "Akukho siginali" (okanye Akukho mqondiso, ngesiNgesi). Kungoko kuphakama le mibuzo: Kwenzeka ntoni? Kutheni umabonakude wam engandixeleli nto? Kwaye, ngaphezu kwako konke: ndingenza ntoni ukuyisombulula?
Alithandabuzeki elokuba le yimeko ngandlel’ ithile edimazayo. Nangona kunjalo, ukuyicombulula kwiimeko ezininzi akuyimfuneko ukubhenela kwinkonzo yoncedo lobugcisa. Licebo lokugqibela elo. Ngaphambi koko, ungazama ezinye ze izisombululo esiyichazayo kweli nqaku.
Ithetha ukuthini impazamo ethi "Akukho siginali"?
Phantse zonke iimpawu zikamabonakude zixhobisa iiseti zazo nge indlela yoqhagamshelo oluzenzekelayo. Phantsi kweemeko eziqhelekileyo, oku kusetyenziselwa ukubona isixhobo kwaye sibonise kwiscreen xa sicofa iqhosha lamandla kulawulo olukude.

Xa kukho ingxaki yonxibelelwano lwenethiwekhi, kuvela umyalezo usilumkisa ukuba akukho mqondiso ekufuneka siwulungise sisebenzisa ezinye zeendlela ezichazwe ngezantsi:
Izisombululo "kwiTV yam ayindixeleli mqondiso"
Zininzi iindlela zokusombulula le ngxaki ikruqulayo esikhe sidibane nayo xa sifuna ukubukela umabonakude. Ngamnye wabo uya kuxhomekeka kwimeko yengxaki. Ezi zezona zixhaphakileyo. Sicebisa ukuba uzizame ngokulandela indlela efanayo esizicebise ngayo:
Linda imizuzu embalwa
Njengoko kuvakala kungenangqondo, isisombululo sokuqala sesi: ungenzi nto, linda nje. Ukuba, umzekelo, sijonge itshaneli ye-DTT, mhlawumbi impazamo ibangelwa yingxaki yoxhumo lwexeshana edla ngokusonjululwa ngokukhawuleza ngaphandle kokuba sithathe naliphi na inyathelo.
Vula uvale iTV
Esi sisisombululo sokuqala esifanele sizame, kuba ngaphezu kwesinye isihlandlo kwanele ukulungisa izinto. Kufuneka cima isixhobo, linda imizuzu embalwa uze uyivule kwakhona ukuze iqalise kwakhona.
Oku kukulingana nesisombululo se-classic "cima kwaye sivule" ukuba zonke izazinzulu zekhompyutheni zisebenzise ngexesha elithile ebomini babo ukulungisa ezinye iimeko. Ukuba ingxaki iyaqhubeka, kufuneka uye kwinqanaba elilandelayo.
Jonga isiseko se-eriyali
Mhlawumbi uphawu lwe-eriyali ukungafikeleli kumabonakude wethu ngokuchanekileyo. Kule meko, khangela i-antenna socket, ukujonga ukuba ixhunyiwe kumabonwakude. Ngamanye amaxesha uqhagamshelo lulungile, kodwa intambo esetyenziswayo indala okanye ikumgangatho ophantsi kwaye ifuna ukutshintshwa.
Jonga uqhagamshelwano lweHDMI
Umabonakude wam awundixeleli luphawu: kwiimeko ezininzi ingxaki ikwiintambo okanye kumazibuko e-HDMI (ujongano oluphezulu lwemultimedia). Kuqhelekile ukuba udibaniso "umdaniso" okanye izibuko zonakaliswe. Izisombululo ezinokwenzeka kukusebenzisa enye i-port ye-HDMI yamahhala kwi-TV okanye ithathe indawo ye-port eyonakalisiweyo, ukulungiswa okulula ukuba nayiphi na i-technician enokuyenza.

Ngamanye amaxesha i-TV ayibonisi uphawu ngenxa ye Imposiso yoKhuseleko lweDijithali yoMxholo oPhakamileyo weBandwidth (HDCP), elungiswa ngokukhupha isixhobo sangaphandle esiqhagamshelwe esibangela impazamo. Kwezi ntsuku kunqabile kakhulu ukufumana oku njengoko phantse zonke iiTV zanamhlanje zithobela i-HDCP.
Buyisela useto lomzi-mveliso
Ukuba yonke enye into ayiphumelelanga, imbumbulu yokugqibela kwigumbi buyisela useto lwasefektri. Ngokwenza oku, umyalezo othi "Akukho siginali" uya kuthi shwaka, kodwa zonke iitshaneli kunye nezicwangciso nazo ziya kucinywa, okuya kufuneka siphinde siqwalaselwe.
Ezinye iingxaki eziqhelekileyo
Ngaphandle nje kombuzo othi "umabonakude wam undixelela ukuba akukho mqondiso", zininzi ezinye iingxaki esinokudibana nazo xa sivula umabonakude ekhaya. Ezi zezinye zezona ziqhelekileyo, kunye nezisombululo zazo:
itv yam ayizuvula
Xa oku kusenzeka, ingqiqo isixelela ukuba kwindawo yokuqala kufuneka khupha izizathu ezilula (esithi ngamanye amaxesha singayihoyi): khangela ukuba iibhetri zolawulo olukude aziphelelwanga, kwaye intambo yamandla kamabonakude iqhagamshelwe ngokuchanekileyo kwimibhobho engundoqo. Kwaye kukho umbane ekhaya, kunjalo.
Ngamanye amaxesha oku kulungiswa ngokukhupha intambo, ukulinda isiqingatha somzuzu, kwaye uyifake kwakhona. Kodwa ukuba akukho nanye yale nto isebenzayo, awunakukhetha ngaphandle kokubiza inkxaso yobugcisa.
Isikrini sikamabonwakude siba mnyama
Ukuba i-TV ivuliwe (isibane esibomvu siya kusixelela) kodwa isikrini sibonakala simnyama, kunokwenzeka ukuba ukusasazwa kwe-DTT okanye ukusasazwa kwesiteshi kuye kwaphazamiseka ngenxa yesizathu esithile. Ukuba kuyenzeka kuthi ngelixa siqhagamshelwe kwi-a isixhobo sangaphandle njengomdlali weDVD okanye ikhonsoli yomdlalo, kuya kufuneka ujonge impazamo kuyo. Isikrini esimnyama sinokubakho ngenxa yoxhulumaniso olubi lwentambo ye-HDMI, esiya kufuneka siyihlolisise.
