Musa bukele i-TV: izimbangela kanye ukulungisa

Njenganoma iyiphi enye imishini, amathelevishini angehluleka ngokuzumayo behluleka. Nokho, kulokhu kuhluleka zenzeka kungakhathaliseki isikhathi ukusebenza idivayisi. Ngokwesibonelo, ngezinye izikhathi ke akufakwanga TV. Lapho sizama usikhanyise izinkomba ezahlukene Blink, bese uchofoza edluliselwe. Kungenzeka kukhona ezinye "izimpawu". Ake sibheke ukuthi kungani ama-TV esenqaba ukusebenza futhi yini okufanele uyenze esimweni esinjalo.

zezimbangela ezivamile iphutha

Le nkinga singenzeka ngenxa yezizathu ezihlukahlukene. Kwenzeka ukuthi LED blink njengenjwayelo, kodwa TV namanje akafuni ukusebenzisa. Futhi, inkomba zibomvu, kodwa Idivayisi ayikwazi ukungabi remote control kanye Ayibalwa. Ngokuvamile awusebenzi ukuyivala i-TV njengoba elawulwa kude, futhi inkinobho. Umzimba omkhulu le nkomba akukukhanyiselanga. Olunye uphawu - into ukuchofozwa, ukudlidliza ngaphakathi izindlu. Idivayisi ukhiqiza imisindo ehlukahlukene ngezinye izikhathi kakhulu impela kungavamile, kodwa namanje ingavuli.

LED flash

Uma ngabe i-flash umzimba, idivayisi self-ukuxilonga futhi ngokushesha ukuthola imbangela yenkinga. Ngokuvamile ku onobuhle ezahlukene kuyabonakala ukuthi isibani noma LED ukhombisa izikhathi eziningana. Ngakho utshela mayelana nephutha ethize. Ingxenye ikhodi ngabo ingatholakala bhukwana imfundo. Abenzi-TV ezifana "Sony", "Philips", "Panasonic" kanti elinye inamandla umsebenzi self-ukuxilongwa. Emaphakathi processing unit idatha isondo ithola imininingwane ezintweni amadivaysi main kanye amabhlogo. Uma uthola i-node okuyiphutha, CPU izokhiya out lokuvala. Ngakho-ke, uma ungenawo uvule TV "Philips", kodwa le nkomba agqoke, kumelwe ufunde iphutha bese wokufunda ke. Khona ungazama ukulungisa inkinga. Futhi afana uphawu kwenzeka uma imisebenzi TV panel njengoba qapha ikhompyutha. Uma i-PC kusala imodi yokulala noma kuvaliwe ke uma ucindezela inkinobho vula isilawuli kude LCD panel LED ngeke blink izikhathi eziningana.

LED zihlale

Khanyisa diode likhipha yazisa umsebenzisi ukuthi idivayisi amandla Iyunithi enikeza ngokuvamile uthola supply voltage. Yini okumele uyenze uma ungenawo uvule TV futhi akasabeli amasignali kusuka elawulwa kude? Okokuqala - zama ulifake izinkinobho-TV. Mhlawumbe le nkinga ibangelwa operation engalungile elawulwa kude noma ezinye iphutha ezihambisana naso. Kodwa ngokuqinisekile ngeke lapha kufanele kusolwe yena TV. Uma ungenalo uvule TV LG nesipiliyoni izimpawu ezinjalo, khona-ke wonke into e ukumelana Ceramic 4.7 ohms. Itholakala eduze CPU - siphukile. Njengoba ezothatha isikhundla Resistor bantu bayosiza ekubuyiseleni idivayisi. Ungathatha izenzo ezithile. Okokuqala hlola ukuthi amabhethri OK elawulwa kude futhi ukuthi noxhumana nabo oxidized. isheke Landelayo kurediyetha infrared kanye ubuqotho bayo. Khona inkinobho sitholakale. Zingaba okunamathelayo, ngenxa yalokho iphaneli futhi akasabeli imiyalo. Uma TV "Samsung" Ayibalwa, kodwa ukukhanya uvaliwe, imbangela ke kumele ifuneka zikagesi. Okuthile kwabangela ushintsho property capacitors, ngakho amandla supply ayisakwazi ukunikeza idivayisi evamile ekuqaleni-up. Caveat kuphela - kwencazelo kwasendaweni iphutha kuzothatha isikhathi esithile. Futhi, ochwepheshe batusa ukuqaqa control panel bese uhlanza it kusuka ngaphakathi. Bavame buthelela uthuli. Lena akuyona indlela engcono kakhulu kuthinta ukusebenza idivayisi. Uma akude sesivalekile ikhofi, ubhiya noma iluphi olunye uketshezi, futhi ayikwazi ukusebenza ke kulula ukuthenga entsha. Uma ucindezela izinkinobho phezu LCD ukulawula TV panel ingavuli ke kukhona izinketho amabili kuphela, nokuthi kungani kwenzekile.

Ukuvikelwa

Lona omunye izimbangela. TV Kulesi simo angenza imizamo ukuqala, kodwa ngaphakathi imizuzwana embalwa, isikrini uya alinalutho noma ayeke ngokuphelele ephendula yonke imizamo ukusebenzisa. Imbangela enkulu futhi ethandwa kakhulu yale nkinga - ukwahluleka ngogesi inethiwekhi yakho yasekhaya. Uhlelo ugesi e-TV yesimanje uthanda ozinzile futhi izinga ukunikezela. Indlela ephumelela kunazo ukusiza ukuxazulula le nkinga - it is ngokuphelele uyeke lingakunika amandla kudivayisi. Lokhu kungenziwa ngokudonsa plug aphume isokhethi. Emva kwesikhatsi lesitsite ukuze alulame. Uma kukhona izinkinga obungapheli ukucindezeleka ke ikhambi best - iyona ukufakwa TV nge stabilizers uninterruptible ugesi, noma ngisho ngokusebenzisa standard amandla emapheshana. Kodwa okuhle nakakhulu, uma ufuna ukugwema lezi zinkinga, cisha iphaneli lapho ushiya indlu. Khona-ke ngeke ezibuza "kungani ungaphendukeli ku-TV."

Amaphutha processor

Modern flat-panel ifakwe omningi control electronics. Schematically, zingabantu PC encane nge CPU ahlukene elawula CPUs konke lokhu kubalulekile. Ngokwesibonelo, uma sicabangela Umdwebo olotshiwe LED-TV, ubonakala ukuthi voltage control kuya LED-diode sidla ngokusebenzisa Stand-by lokuxhumana Transistor. Uma kukhona iphutha, khona-ke i-TV ngeke uvule. Khona-ke ungenzi ngaphandle wenziwa ochwepheshe Service Centre. Yiqiniso, uma ulwazi kanye namakhono adingekayo, ungazama ukulungisa inkinga ngokwakho. Nokho, Inkinga ukuthi kule domain yomphakathi azikho wesifunda namathelevishini kagesi. Futhi silungise iphaneli kunzima kakhulu ngaphandle kwabo.

TV hhayi esitshalweni, ikhanyisa off

Lezi zimpawu zihlobene ngokuqondile noma ngokungaqondile yokungabi namandla kagesi. Uma isibani liphele ke idivayisi ngabe ukusebenza njengoba evamile (akukho lapho kuboniswa khona). Uma lokhu kwenzeka, khona-ke ningatatazeli. Okokuqala, udinga ukususa zonke izinkinga ezingase uqondiswa ngokuzimela. Kodwa kunezimo ngokungenakulinganiswa neyinkimbinkimbi ngokungaphezulu. Ngokwesibonelo, ungaphambuki TV LG, futhi inkinga itholakala zokugwema ukuphuka of a Resistor-fuse. Ngalezi resistors kuya wesifunda uthola voltage ka +12 V Ngemva esikhundleni isici TV isebenza kwimodi ejwayelekile.

Akukho amandla kwayo kuleyo ndawo yokuhweba

Ngezinye izikhathi buthule kuvaliwe la magagasi wesifunda ngo Switchboards. Amaphutha zenzeka kakhulu lapho uphuma khona. It is ngomshini inkomba noma multimeter. Uma kungekho amandla, hlola umshini. Uma kungasebenzi, ukushintsha into yokuxhuma.

okuyiphutha isandiso intambo

Lesi isizathu ezivamile kungani ungaphendukeli ku-TV. Hlola kungaba elula - uma iyunithi kusuka lapho uphuma khona odongeni isebenza, futhi intambo isandiso akafuni ukusebenzisa ke inkinga ngokucacile isahola.

Ukukhetha imodi engavumelekile

Kaningi kuyenzeka ukuthi umuntu ngephutha noma ngamabomu ekhetha izindlela ezingafanele wokusebenza. Kulokhu TV kuvaliwe hhayi luvulwe noma bangene mode ubuthongo. Kulokhu, ngeke kabusha izilungiselelo zasembonini.

Ukungasebenzi zikagesi

Njengoba kushiwo ngenhla, uma ungenawo uvule TV Philips, lokhu kungenxa kusukela ukuhlukaniswa zikagesi. Ngokwesibonelo, ngesizathu esithile ashisiwe resistors noma capacitors. Inkinga yamanje - fuses. Ukuxilonga kanye nokulungiswa lezi amaphutha kungcono ishiyelwe ochwepheshe. Self ukulungisa kuyabiza kakhulu. Uma ungenalo uvule "Philips" TV, lokhu kungenxa capacitor ephukile okuphakela amandla. Ngenxa yalokho, circuit 13 sidla e olufanele 18.5 esikhundleni. Kuyinto ngokuvamile imbangela yokwehluleka. Ngaphandle ulwazi oludingekile ukuze sibone inkinga ngokwakho kunzima kakhulu - lena umsebenzi wenkonzo onjiniyela.

isiphetho

Uma TV "Samsung" ingavuli (futhi lokho kusebenza kuwo wonke brand), akusho ukuthi sinqamukile phakade. Singasho savuka ngosizo izindlela ezilula. Kodwa uma inkinga kule capacitor noma Resistor, akudingekile ukwenza ukulungiswa ngaphandle isipiliyoni esifanele.
