Ukuqhekeka xa i-TV isebenza: yintoni ebangela oko kwaye wenze ntoni

Siyaqonda ukuba kutheni iTV iqhekeka ngexesha lokusebenza, emva kokuyivula kunye nokucima, kwaye yintoni enokuyenza kwimeko ethile (LCD, plasma, kinescope). Ukwenzeka kwayo nayiphi na ingxolo engaqhelekanga ngexesha lokusebenza kwe-TV kusoloko kubangela ukudideka kumsebenzisi. Kodwa oku akusoloko kubonisa ubukho nakuphi na ukungasebenzi kakuhle, ukuwohloka. Ngokomzekelo, ukuba i-TV eyenziwe yi-LG okanye i-Sony iyaqhekeka xa ivuliwe (ngexesha lokuqala le-5 ukuya kwe-10 imizuzwana), oku kuthathwa njengento eqhelekileyo. Imemo ehambelana nayo iyafumaneka nakwimiyalelo yobugcisa esemthethweni. Nangona kunjalo, ukuba ngaphambili i-crack yayingekho ngokupheleleyo, kwaye ngokuhamba kwexesha yaqala ukuqina, ngoko ngeqondo eliphezulu lokunokwenzeka oku kukuphazamiseka kobugcisa.

Yintoni ekufuneka uyazi malunga cod, cofa xa TV ivuliwe

Kunokwenzeka ngokwemeko ukwahlula iindidi ezi-3 eziphambili zeemeko apho iTV iqhekeka kwaye icofa ngexesha lokusebenza:

1. Umtshato wasefektri . Kwiimeko ezininzi, inxulunyaniswa nofakelo olungachanekanga lwenkqubo yesithethi (izithethi ezingcangcazela ngokugqithisileyo ngexesha lokuphuma kwesandi) okanye ngokusebenza okungafanelekanga kwezinto zobonelelo lwamandla (ngokukodwa, ukukrwitsha).
2. Ukuphulwa kwemigaqo yokusebenza . Zonke zichazwe ngokweenkcukacha kwincwadana yomsebenzisi, ekuyimfuneko ukuba inikwe iTV. Izizathu eziqhelekileyo: ecaleni kweTV yi-router, i-oven microwaves, ifowuni ephathwayo, kunye neminye imithombo yokuphazamiseka kwerediyo. Ukuqhekeka kunokwenzeka xa i-TV iqhagamshelwe kwindawo ephumayo eqhagamshelwe kwezinye izixhobo zombane ezisetyenziswa kakhulu ngoku (phakathi kwama-700 kunye nama-800 Wh).
3. Ukuqhekeka kobugcisa . Oku kuyinyani ngakumbi kwiiTV ezisele zineminyaka engaphezu kwe-5 ukuya kwe-7 ubudala ukususela kumhla wokuthenga, ngelixa zisetyenziswa ngokusebenzayo (oko kukuthi, zivulwa yonke imihla).

Iziphene zefektri zivela, njengomthetho, kwiintsuku zokuqala ezi-3 ukuya kwezi-10 ukususela kumhla wokuthengwa kweTV. Kwaye kwezi meko, akukho ngxaki ngokutshintshiselana kwezixhobo. Kodwa kwakhona kufuneka ukhangele ukuba umsebenzisi uyaphula imigaqo yokusebenza echazwe kwincwadana. Amaxesha amaninzi iba:

• I-TV ixhunyiwe kwi-socket, apho ezinye izixhobo ezi-2 – 3 zinikwe amandla;
• I-TV isondele kakhulu eludongeni okanye kwi-radiator (ibangela ukushisa okukhulu).

Iimeko eziqhelekileyo apho iTV inokuthi “iqhekeke”

Kukho izizathu ezininzi zokuba kutheni iTV iqhekeka ngexesha lokusebenza. Isandi esongezelelekileyo singenzeka zombini xa uyilayita naxa iTV sele isebenza okanye icinyiwe ngokupheleleyo (oko kukuthi, itshintshelwa “kwimowudi yokulinda”):

1. Ukuqhekeka xa uvula iTV  kwiimeko ezininzi kuyinto eqhelekileyo kwaye ayibonisi nakuphi na ukusilela okanye ukungasebenzi kakuhle. Ikakhulu iyenzeka ngenxa yokuhanjiswa kombane kwindlela yokunyuka kokusetyenziswa kwangoku. Ngaba oku kubonisa ukuba umabonwakude usenokungaphumeleli kungekudala? Hayi.
2. Ukukrazula okuzolileyo ngexesha lokusebenza . Ibonisa ukungasebenzi kakuhle ekusebenzeni kwe-transformer okanye ukulungelelaniswa okungahambi kakuhle kokujika kwenkqubo yokuphambuka.
3. Ukukhenkceza okuzolileyo xa iTV icinyiwe , njengomthetho, ibonisa ukuba kufutshane kwimithombo yokuphazamiseka kwerediyo. Ezi mhlawumbi zii-oveni zemicrowave okanye iirotha (iirutha). Kwaye inokubonisa amandla ombane angazinzanga kwinethiwekhi yombane apho iTV iqhagamshelwe kuyo. Ngokukodwa, esinye sezona zizathu zixhaphakileyo kukunyuka kwexesha elifutshane lombane ngaphezu kwe-235 – 240 Volts okanye i-frequency mismatch ye-50 Hz.

Kukwafanelekile ukukhankanya ukuba iiTV zizixhobo ezintsonkothileyo ngokobuchwephesha. Kwaye uninzi lwamacandelo kuzo zenziwe ngeplastiki kunye nentsimbi. Ngethuba lokusebenza, i-TV ishushu kancinci. Kwaye ukusuka kwikhosi yesikolo yefiziksi kuyaziwa ukuba imizimba iyakhula kule meko. Ngokufanelekileyo, oku kunokuba ngumthombo we-cod. Kodwa akakho ngokusisigxina.

Ukuqhekeza iiTV ngekinescope

Nangona oomabonwakude abanjalo bengasaveliswa ngabavelisi abaninzi, basasetyenziswa ngokukhutheleyo kwiintsapho ezininzi. Kwaye kubo, ukukhwabanisa xa kuvuliwe okanye kuvaliwe yinto eqhelekileyo, ebonisa “ukukhutshwa kwe-kinescope” (oko kukuthi, inkqubo iqhutywe ephelisa intlawulo ye-static). Ukuba umfanekiso uqhelekile ngexesha lokusebenza, akukho zixhobo zegraphic zivelayo, ngoko akufanele ukhathazeke malunga nokuqhekeka okunokwenzeka. Kwaye ukuba i-TV set-top box iyaqhekeka, ke le nto ikwajongwa njengesiqhelo. Kodwa kuphela ukuba ukuqhekeka akuhlali ngaphezu kwe-10 – 15 imizuzwana emva kokuyivula okanye ukuyicima. Zonke ezinye iimeko zinokuthathwa njengezingaqhelekanga, oko kukuthi, zifuna ingqalelo kwi-telemaster. Ukuba ukuqhekeka kukhatshwa ziindidi ezahlukeneyo ze “artifacts” kwiscreen, ukwakheka kwengxolo emfanekisweni,

Kuyingozi ukusebenzisa iTV kweli lizwe! Kufuneka ikhutshwe ngokupheleleyo amandla, emva koko uqhagamshelane neziko lenkonzo.

Xa ukuqhekeka kubonisa ukungasebenzi kakuhle

Ukuba ukuqhekeka kufana nesandi sompu we-stun, ke oku kubonisa ukuchithwa kombane phakathi kwezinto zebhodi yesekethe eprintiweyo okanye ukunikezelwa kwamandla. Kwaye oku sele kubonisa ubukho bokungasebenzi kakuhle kwezobugcisa. Kuyacetyiswa ukuba ucime ngokupheleleyo amandla kwiTV kwaye uqhagamshelane neengcali zeziko lenkonzo ukuze ufumane uncedo.

KUBALULEKILE! Kodwa ukuzama ukukhupha iTV ngokwakho akufanelekanga. Unikezelo lwamandla olufanayo lunomthamo ophezulu we-capacitors. Ukukhutshwa kwabo kwanele ukuzisa ingozi engenakulungiseka empilweni okanye kude kukhokelela ekufeni! Kwaye xa udibanisa, unokonakalisa ngokulula iintambo, iipads zoqhagamshelwano: ukulungiswa okulandelayo kuya kubiza amaxesha amaninzi.

Kutheni kukho ukuqhekeka kumabonwakude kwaye wenze ntoni xa kufuneka ukulungiswa: https://youtu.be/Uov56YpizWg

Kutheni iTV ikhala ebusuku?

Oku kubonisa uqhagamshelwano olubi lweplagi edityaniswe kwi-outlet, okanye ubukho bomonakalo kwi-insulation yentambo yamandla, ebangela ukukhutshwa kwexesha elifutshane langoku. Kwaye oku akwenzeki ebusuku kuphela, ngeli xesha lemini kuphela apho bahlala benikela ingqalelo kubukho bezandi ezingaphandle emsebenzini wezixhobo.

I-TV iyaqhekeka kwaye ayiyi kuvula

Ngamanye amaxesha oku kukwakhatshwa yi-low-frequency okanye i-high-frequency hum. Ibonisa ukungasebenzi kakuhle konikezelo lwamandla okanye umgca wokuskena into. Ukuba i-hum ihamba kunye nomfanekiso okanye i-artifacts yesandi, oku kubonisa ukuba akukho ndlela yokucoca igalelo lombane. Ukuphelisa ngokufakela umkhuseli wokunyuka okanye i-voltage stabilizer.

Izithethi ziyakrazuka

Ukuba izithethi kwiTV ziyaqhekeka xa isandi sesandi sonyuswa, oku kuthetha ukuba inwebu yabo yonakaliswe. Oku kwenzeka ngeeTV ezingaphezulu kweminyaka emi-5 ubudala okanye ukuba umsebenzisi uhlala ebeka inqanaba lesandi ukuya kuthi ga kwinqanaba eliphezulu. Ungayilungisa oku mhlawumbi ngokutshintsha izicwangciso zokulinganisa (ukunciphisa ibhalansi ye-bass) okanye ngokutshintsha ngokupheleleyo i-acoustics. Indlela yokusebenza isenokuba kukudibanisa izithethi zangaphandle nge-RCA port (3.5mm) okanye ngeBluetooth (i-Smart TV kuphela).

Yintoni onokuyenza ngezandi ezingaphandle ngexesha lokusebenza kweTV

Iintshukumo ezicetyiswayo ukuba iTV iyaqhekeka:

1. Qinisekisa ukuba indawo eqhagamshelwe kuyo i-TV ine-voltage echanekileyo kunye ne-frequency. Kwiteknoloji yanamhlanje, izixhobo zombane jikelele zifakwe. Bakuvumela ukuba usebenzise amandla ombane weTV kuluhlu ukusuka kwi-110 ukuya kwi-220 volts. I-frequency kufuneka ihlale i-50 Hz.
2. Qinisekisa ukuba i-outlet isebenza ngokupheleleyo. Ukuqhekeka kungabonakalisa ukudibana okungalunganga phakathi kweplagi kunye “neepetali zokumisa” ezingaphakathi kwendawo yokuphuma.
3. Qinisekisa ukuba akukho monakalo we-insulation kwintambo yamandla. Kwakhona kunokuba yi-microcracks engabonakaliyo kwiindawo zokugoba.
4. Qinisekisa ukuba ukuqhekeka kwenzeka kwi-TV. Izandi ezingaphandle zinokukhutshwa ziibhokisi ezahlukeneyo ze-TV (i-DVB2 isamkeli, isidlali-DVD, isamkeli sesathelayithi, inkqubo yesithethi sangaphandle, njalo njalo).
5. Susa kangangoko unako (ubuncinci iimitha ezi-3) izixhobo ezinokuba ngumthombo wophazamiseko lukanomathotholo. Ngokukodwa, iirotha, ii-oveni ze-microwave, ii-GSM eziphindayo, ii-amplifiers ze-WiFi, iifowuni eziphathwayo kunye nezingenantambo, iipadi zokudlala ezingenazingcingo, iikhibhodi, iimpuku zekhompyuter, kunye nezinye izixhobo zeBluetooth. Zonke zinokubangela ukuqhekeka kwizithethi zeTV, ngakumbi kwiimodeli ezindala (apho kungekho mgangatho uphezulu wokuhlukaniswa kwe-acoustic kuphazamiseko lukanomathotholo).

Ukuba zonke iingcebiso ezingentla kunye neengcebiso azizange zizise umphumo oyifunayo, ngoko kuyacetyiswa ukuba ufune uncedo kwiziko lenkonzo eligunyazisiweyo lomenzi. Njengomthetho, iinkcukacha zakhe zoqhagamshelwano ziboniswe kwincwadana yomsebenzisi.

Lilonke, i-cracking ngexesha lokusebenza kweTV ayisoloko ibonisa ukuba iphosakele okanye kufuneka isiwe kwiziko lenkonzo yokuxilongwa. Ukuba oku kwenzeka kuphela xa uyilayita kwaye uyicima, ke oku kuqhelekileyo kwi-99% yamatyala. Xa i-cracking ihlala rhoqo okanye ihamba kunye nokuphazamiseka kwesikrini, oku kubonisa ubukho bokungasebenzi kakuhle kwezobugcisa.
