• kuvela imivumbo emi nkqo enemibala emininzi;
• umfanekiso uba nzima ukuwubona.

Okokuqala kufuneka ufumanise: iTV ayibonisi, kodwa isandi yintoni ingxaki. https://cxcvb.com/question/polosy-na-kartinke

Ukuphulukana noqhagamshelwano

Ingxaki enjalo ingenzeka ngenxa yokuba i-oxidation epheleleyo okanye inxalenye yabafowunelwa iyenzeka. Ukuchonga umthombo wengxaki, kwanele ukujonga ngokubonakalayo izihlanganisi. Ukuba ukungcola okanye ukulandelwa kwee-oxides kufunyenwe kwiipads zoqhagamshelwano, kuya kufuneka zisuswe. Emva koko, ungaphinda ufake intambo kwisokethi yebhokisi eseti-phezulu kunye nomamkeli weTV. Le nkqubo iqhutyelwa ngokungqongqo kunye nezixhobo ezinqanyuliwe kunikezelo lwamandla. https://cxcvb.com/kak-podklyuchit/cifrovuyu-pristavku-k-televizoru.html Esinye isizathu sokuba kutheni iTV ingabonakali ngelixa kukho isandi kwaye kungekho mfanekiso umonakalo womatshini kwintambo ehambelanayo. Ukuba kukho i-kinks okanye i-creases, ke ii-cores eziphetheyo zangoku zihluleka. Ngaphambi kokulungiswa kwengxaki, kufuneka kuhlolwe ngokucokisekileyo ucingo. Ukuba kukho umonakalo obonakalayo, ikhebula kuya kufuneka litshintshwe. Kule meko, kubalulekile ukuqwalasela ukuhambelana nomzekelo wesixhobo esixhunyiwe. Ke, umgangatho weHDMI uyafumaneka kwiinguqulelo ezininzi.

Ukuba umonakalo ufunyenwe, kucetyiswa ukuba ulungise. Oku kusebenza kwiisokethi ezivulekileyo, iiplagi ezine-insulation eyonakalisiweyo kunye nemiphetho ephukileyo, kunye neengcingo ezine-frayed kunye ne-twisted. Kubalulekile ukuqwalasela ukuba ukusebenza kwezixhobo kule fomu kunokubangela isiphaluka esifutshane kunye nokungasebenzi kakubi.

Iingxaki zamandla

Ukuba iTV ayibonisi, kodwa kukho isandi, oku kunokubangelwa ukuhla kwamandla ombane. Ngenxa yokunyuka okunjalo, ngamanye amaxesha umonakalo ongeyena ubalulekileyo uyenzeka. Kwakhona, ii-subsystems zokuguqulwa kombane ziyasilela ngendlela ekhawulezileyo. Ukuba oku kuyenzeka, isikrini siya kuhlala simnyama xa isixhobo sivulwa. Kodwa emva kwexesha elifutshane lokusebenza umamkeli weTV, umfanekiso usavela.

Ukuba kukho i-bulges, ke kufuneka itshintshwe ngamatsha. Ezinye iintlobo zovavanyo ziya kufuna ukusetyenziswa kwesixhobo sokulinganisa i-elektroniki.

Bonisa imatrix

Xa kukho isandi, kodwa akukho sikrini esimnyama kwiTV, isizathu sinokuba kwi-matrix. Eli candelo libandakanya amacandelo amaninzi:

• umaleko weeseli zekristale zolwelo ezinokufihlwa okulawulwayo;
• iinkqubo zokukhanyisa kunye nomqhubi onika amandla ombane;
• iluphu yokuhanjiswa kwedatha;
• iinkqubo zokuguqula umqondiso.

Enye yezinto ezidwelisiweyo inokusilela. Esi sizathu esiqhelekileyo sokuba kutheni iTV inesandi kodwa ingenamfanekiso. Ukonakaliswa kwe-matrix yeseli kuhlala kubangelwa kukothuka, utshintsho olukhawulezileyo lobushushu, ukugcwala okugqithisileyo kunye nezinye izinto ezinefuthe.
Ukuba ukusilela kuye kwavela ukuba akungabalulekanga, ke amabala kunye nemivimbo ibonakala kwiscreen. Umbala wabo unokuba mnyama okanye unemibala (engalunganga ngokumalunga nomfanekiso wonke). Ukuba inani elikhulu leeseli zonakalisiwe, umboniso uya kucima ngokupheleleyo. Kwiimeko ezinqabileyo, i-matrix yonakele ngenxa yesekethe emfutshane. Iintambo zedatha ngumcu obhityileyo weplastiki apho iingoma zokuqhuba zifakwa khona. Izinto ezinjalo kulula ukuzonakaliswa. Kwezinye iimeko, iintambo ziyaphuma kwiikhonkco ngenxa yokungcangcazela. Nangona kunjalo, i-soldering yabo iya kuba nexabiso eliphantsi kunokutshintsha i-matrix.
Ngenxa yoko, kukho isandi, kodwa akukho mfanekiso, okanye umfanekiso uqala ukusasazwa ngokuphazamiseka. Kwakhona, iingxaki nge-loop yedatha zinokuzibonakalisa koku kulandelayo:

• iiripples kunye nezinye izinto ezigqwethekileyo zivela ngamaxesha athile kwiscreen seTV;
• utshintsho lombala luyabonakala – kwiindawo zomntu okanye kwindawo yonke yesiboniso;
• umfanekiso uyanyamalala, kodwa unokubuya ukuba ucofa i-TV kancinci.
