Musani ukubheka kwi TV: unobangela kunye nokulungiswa

Njengazo naziphi na ezinye izixhobo, oomabonwakude banokusilela ngesiquphe lungapheli. Nangona kunjalo, ezi neentsilelo kwenzeka nokuba ixesha yokusebenza kwefowuni. Ngokomzekelo, maxa wambi ayiqukwanga TV. Xa uzama onokukubuyisa oko umva ngeempawu ezahlukeneyo kwekhesa, uze ucofe edluliselwe. Kusenokubakho ezinye "iimpawu". Makhe sijonge ukuba kutheni nomabonakude wenqaba ukusebenza kwaye nomawukwenze kwimeko enjalo.

ezibangela Common of fault

Le ngxaki kwenzeka ngenxa yezizathu ezahlukeneyo. Kuyenzeka ukuba LED blink njengesiqhelo, kodwa ke TV akafuni ukubaleka. Kwakhona, kuvezwa ibomvu, kodwa isixhobo akunakuba remote control kwaye ayiqukwanga. Ngokufuthi oko iyeka umabonwakude nje remote control, kunye iqhosha. olo alunasikhanyisi Umzimba ephambili yale isalathisi. Olunye uphawu - into ecofa, imbibhazo ngaphakathi izindlu. Le fowuni velisa ezahlukeneyo izandi ngamanye amaxesha kakhulu engaqhelekanga, kodwa akuthethi uvule.

LED flash

Ukuba le flash emzimbeni, isixhobo self-lokuxilonga ngokukhawuleza ukufumana unobangela ngxaki. Amaxesha amaninzi kwimodels ezahlukeneyo kunokubonwa ukuba isibane okanye LED idanyazise izihlandlo eziliqela. Ngoko ke isixelela impazamo ethile. Inxalenye ikhowudi zazo zifumaneka kwi-yesikhokelo. Kubavelisi TV ezifana "Sony", "Philips", "Panasonic" kunye omnye umsebenzi self-kokuxilongwa. Le iyunithi yokusebenza engundoqo ye data sidinwe ifumana inkcazelo evela izixhobo ezingundoqo iibhloko. Ukuba ufumana udumbo eziphosakeleyo, i CPU uya ukuvalelwa ngaphandle ukuvalwa. Ngoko ke, ukuba kuwe ungamnikeli kwi TV "Philips", kodwa inkomba obumbeneyo njengembumbulu, kufuneka ufunde i isiphoso ukuwuqonda ngayo. Ngoko unga zama ukulungisa lengxaki. Kwakhona efanayo uphawu kwenzeka xa imisebenzi TV-panel njenge esweni computer. Ukuba PC okusindileyo imo yokucima okanye icinyiwe, ngoko xa ucinezela LCD lenjongo LED ekude iqhosha mbane kuya blink izihlandlo eziliqela.

LED zisoloko

Light diode esikhupha yazisa umsebenzisi ukuba iyunithi isixhobo umbane ngokuqhelekileyo ufumana supply ombane. Kufuneka wenze ntoni xa kuwe ungamnikeli kwi TV kwaye modem imiyalezo evela kwi control kude? Okokuqala - zama ukubandakanya kunye bamaqhosha TV. Mhlawumbi le ngxaki ibangelwa ukusebenza olungachanekanga kolawulo kude okanye ezinye imposiso enxulumene nayo. Kodwa ngokuqinisekileyo hayi apha ityala ngokwakhe TV. Ukuba kuwe ungamnikeli kwi TV LG kunye namava ezinjalo iimpawu, yonke ke loo nto ukuxhathisa yodongwe ka-4.7 ohms. Le ibekwe kufuphi CPU - yaphulwe. Ukufakela resistor kuya kunceda ukubuyisela ifowuni. Ungathatha iintshukumo ezininzi. Okokuqala khangela ukuba neebhethri Kulungile remote control kwaye nokuba abafowunelwa oxidized. Itshekhi Next radiator infrared kunye ingqibelelo yayo. Emva iqhosha isifo. Iiplastiki incangathi, ngenxa yoko kwiqela lenjongo kwaye akaziphenduli imiyalelo. Ukuba TV "Samsung 'ayiqukwanga, kodwa ukukhanya icimile, ngoko unobangela kufuneka kucelwa amacandelo elektroniki. Into eyenza utshintsho kwi iimpawu capacitors, ngoko ke unikezelo mandla kuphinda ukunika icebo eqhelekileyo start-up. Le caveat kuphela - kwenkcazo lethu tyala liya kuthatha ixesha elithile. Kwakhona, iingcali Siyaleza ibattery panel yolawulo ce evela ngaphakathi. Badla angemi uthuli. Le akuyona indlela engcono kuchaphazela ukusebenza ifowuni yakho. Ukuba okude sele zizaliswe ikofu, ibhiya okanye naluphi na ulwelo, kwaye akakwazi ukusebenza, kulula ke thenga elitsha. Ukuba ucinezela amaqhosha kwiqela lenjongo control TV LCD ingavuli, ngoko kukho iindlela ezimbini kuphela, nesizathu sokwenzeka koko kwenzekayo.

yokuvikela

Lo ngomnye unobangela kunokwenzeka. TV Kule meko ukuze iinzame ukuqala, kodwa emva kwemizuzwana embalwa, nesisitheliso iya ingenanto okanye ayeke ngokupheleleyo ukuphendula zonke iinzame ukubaleka. Eyona engundoqo kwaye ethandwa unobangela wale ngxaki - ukwahluleka kubonelelo ngombane yakho kwinethiwekhi yasekhaya. Le inkqubo yonikezelo amandla nomabonakude mihla uthanda ezinzileyo kunye nomgangatho ubonelelo. Eyona ndlela isebenzayo ukunceda ukusombulula le ngxaki - oku ngokupheleleyo de-amandla ifowuni. Oku kunokwenziwa bawurhuqa kwiplagi ngaphandle kwisokethi. Emva imizuzwana embalwa ukuba zibuye. Ukuba kukho iingxaki ziqhu noxinezeleko, ngoko ke kungcono - ke kubandakanywe TV nge ekwenzeni, unikezelo lwamandla uninterruptible, okanye nkqu imicwe standard ngamandla. Kodwa okuhle bonke, ukuba ufuna ukuthintela ezi ngxaki, cima lenjongo xa eshiya indlu. Ke akuyi uyazibuza ukuba "kutheni vula kwi TV."

Amaphutha iprosesa

Modern flat-panel mayixhotyiswe isixa esikhulu electronic yolawulo. Ngokwalo, ukuba iiPC encinane CPU elahlukileyo ulawula CPUs yonke ebalulekileyo. Ngokomzekelo, xa sicinga Idayagram LED-TV, kuba kubonakala ukuba ombane ulawulo ukuya LED-diode ondliwa nge-stand-ngokudibana kunye transistor. Ukuba kukho isiphoso, ngoko ke TV akayi uvule. Ngoko musani ukwenza ngaphandle abanaluncedo iingcali Kumbindi Service. Kakade ke, ukuba unalo ulwazi kunye nezakhono eziyimfuneko, unga zama ukulungisa le ngxaki. Noko ke, ingxaki kukuba kuwonke-wonke akukho shini yombane. Kwaye ulungise lenjongo Kunzima kakhulu ngaphandle kwazo.

TV ayenziwanga ivuliwe, izibane

Ezi mpawu ziye ezinxulumene ngqo okanye ngokungathanga ngqo kukungabikho kwamandla ombane. Ukuba isibane utshisa ngaphandle, ngoko ke icebo liya kusebenza njengento eqhelekileyo (akukho ebonisa). Ukuba oku kuyenzeka, ngoko musa ukothuka. Okokuqala, kufuneka ukuphelisa zonke iingxaki kunokwenzeka ukuba alungiswe ngokuzimeleyo. Kodwa ke kukho iimeko kunye inzima. Umzekelo, musa vula kwi TV i-LG, yaye ingxaki bubonakala breakage ye resistor-fuse. Ngezi resistors kumphathi wesekethe ofumana lombane +12 V. Emva ngokubuyisela i isiqalelo TV isebenza kwimo yesiqhelo.

Akukho mandla ngamashishini

Ngamanye amaxesha ngokuzolileyo icinyiwe benza okuchasene wesiphaluka switchboards. Iziphene kwenzeka kanye iplagi. Oku axilonge isalathisi okanye multimeter. Ukuba akukho amandla, khangela umatshini. Ukuba ayisebenzi, ukutshintsha i iplagi.

eziphosakeleyo lolwandiso intambo

Esi sisizathu eqhelekileyo kutheni ndivule umabonakude. Khangela kunokuba lula - ukuba iyunithi ukusuka iplagi eludongeni kusebenza, kwaye ingumsipha ukwandiswa akafuni ukubaleka, ngoko ingxaki ngokucacileyo makakhokele.

Ukukhetha mode engasebenziyo

badla Kuyenzeka ukuba umntu ngengozi okanye ngabom ukhetha iindlela ezingafanelekanga yokusebenza. Kule meko TV lucimile kwaye hayi ivuliwe okanye uye imo yokucima izenzo. Kulo mzekelo, iya usethe iyibuyisele olungagqibekanga.

Sibangelwa nezombane

Njengoko kukhankanyiwe ngasentla, ukuba kuwe ungamnikeli kwi TV Philips, oku kungenxa ukusuka yokuwa nezombane. Umzekelo, ngasizathu sithile sayitshisa resistors okanye capacitors. umba nezolo - iifyuzi. Uxilongo kunye nokulungiswa kwezi iziphene kungcono iingcali. ukulungisa Self kuyabiza kakhulu. Ukuba kuwe ungamnikeli ku "Philips" TV, oku kubangelwe capacitor esophukileyo umbane. Ngenxa yoko, umphathi wesekethe 13 esidla ezifanelekileyo 18.5 endaweni. Kudla unobangela ukungaphumeleli. Ngaphandle ulwazi oluyimfuneko ukuchonga ingxaki wena kunzima kakhulu - oku ngumsebenzi iinjineli wenkonzo.

isiphelo

Ukuba TV "Samsung" ayithethi uvule (kwaye oku kusebenza kuzo zonke iintlobo), oko akuthethi akuthethi ukuba yaphukile ngonaphakade. Oko ivuke ngoncedo ngeendlela ezilula. Kodwa ukuba ingxaki kwi capacitor okanye resistor, akukho mfuneko ukwenza ulungiso ngaphandle amava eyiyo.
