CRT kapena CRT TV – bajeti ndi njira yogwirira ntchito (osati nthawi zonse)

CRT kapena kinescope TV ndi TV yomwe imagwiritsa ntchito chubu cha cathode ray (CRT) kapena CRT (Cathode Ray Tube) kuti iwonetse chithunzi. Ma TV a CRT kapena CRT amatchedwa ma TV omwe amatumiza zithunzi pogwiritsa ntchito machubu a cathode ray, kapena kinescopes. Tsatanetsatane yofananayo idagwiritsidwa ntchito m’matembenuzidwe oyambilira aukadaulo, opangidwa m’zaka za zana la 20 mpaka zaka ziro zazaka za zana lino.

Zosangalatsa! Kwa anthu wamba, ma TV a CRT amatchedwa “akale” kapena “mabwalo” chifukwa cha mayanjano wamba.

Chipangizo ndi mfundo ya ntchito

Chipangizo cha kinescopes chikhoza kufotokozedwa mophweka: chubu ili ndi mfuti zingapo zomangidwa, zomwe mtundu wake umagwirizana ndi mtundu waukulu wa mtundu (wofiira, wobiriwira, wabuluu). Pogwiritsa ntchito mtengo wa electron, mfutizo “zikuwombera” chinsalu chophimbidwa ndi phosphor, chomwe chimayambitsa kuwala. Ndi kuwala komwe kumapanga chithunzicho kuchokera kumadontho amodzi.

Zoona! CRT ndiye mtundu wakale kwambiri wa kanema wawayilesi. Kwa nthawi ya 2022, opanga ambiri samapanga zipangizo zoterezi, komabe, zitsanzo zoyambirira zingapezeke kuchokera kwa eni ake ogulitsa.

Ubwino ndi kuipa kwa CRT

Ma TV akale ali ndi zabwino zake:

• Mitundu yosiyanasiyana yogwira ntchito.
• Mitengo yaying’ono ya zida.
• Ukadaulo wodalirika wokwanira, woyesedwa nthawi.
• Kusasinthika kwamtundu wocheperako komanso zithunzi zapamwamba ngakhale pazithunzi zazing’ono.
• Moyo wautali wautumiki (zitsanzo zina zimatha kugwira ntchito zaka 15-25).

Palinso kuipa:

• Kuchepetsa kukula kwazithunzi zaukadaulo (pafupifupi mainchesi 38).
• Miyeso yapamwamba, kuphatikizapo kukula ndi kulemera kwa TV.
• Kukhalapo kwa kupotoza kwa geometric, “flare”, zovuta pakuwunika.
• Kutsalira kwakukulu kumbuyo kwaukadaulo wamakono ndi magwiridwe antchito ochepa, kusatheka kwa ntchito zapamwamba ndi zida zaposachedwa.

Chenjerani! Ma TV a CRT amaonedwa kuti ndi owopsa kwambiri pakuwona: pamlingo wotsitsimutsa pansi pa 100 Hertz, maso amatopa mwachangu, kugwira ntchito mopitirira muyeso komanso mutu kumatha kuchitika.

Chifukwa chiyani CRT TV ndiyo yankho labwino kwambiri pakubwezeretsanso: https://youtu.be/BIudE0uvy9A

Momwe mungasankhire TV ya kinescope

Kusankha TV yabwino kwambiri ya kinescope, muyenera kulabadira mikhalidwe yayikulu:

1. Kuyerekeza kukula kwa skrini . Posankha diagonal ya chipangizocho, muyenera kusankha chipinda chomwe chidzayikidwe. Kwa zipinda zing’onozing’ono, ma TV ang’onoang’ono ndi oyenerera, kwa akuluakulu ndi aatali, muyenera kutenga chophimba chachikulu.
2. Tekinoloje yogwiritsidwa ntchito . Kwenikweni, ukadaulo wa kinescope uli ndi mawonekedwe a 50 ndi 100 Hertz. Kuti muwone bwino kwa nthawi yayitali, ndikwabwino kusankha zida zama frequency apamwamba.
3. Mawonekedwe a Screen . Gawani zowonera 4:3 ndi 16:9. Yoyamba ndi yoyenera kuwonera makanema apa TV pamayendedwe akale – iyi ndi mtundu womwe mbiri yotere ili nayo. Kuti muwone kanema kuchokera ku zimbale kapena makaseti, muyenera kugula widescreen TV.
4. Mtundu wa speaker . Pali zida zokhala ndi sewero la mono ndi stereo. Ngati chojambulira chilibe kanthu, chipangizo chokhala ndi mawu a mono chidzachita. Zolankhula za stereo zimapereka komwe kumamveka bwino. Muyeneranso kulabadira chitsanzo ndi khalidwe la wokamba nkhani: phokoso owonjezera pa ntchito ndi osafunika.
5. Kupezeka kwa zida zowonjezera ndi mapulogalamu . Ma TV akale amatha kusinthidwa ndi mawonekedwe amitundu yamakono.
6. Kukhalapo kapena chiwerengero cha zolumikizira zida zakunja . Ngati mukufuna kulumikiza zida zowonjezera, muyenera kusankha ma TV okhala ndi zolumikizira zoyenera.
7. Kukhalapo kwa mabatani owongolera pagawo lakunja . TV imatha kukhala ndi mabatani onse oyambira komanso zida zonse zakutali. Njira yotsirizayi imapangitsa chipangizocho kukhala chovuta kwambiri.

Zimawononga ndalama zingati kugula TV ya kinescope komanso momwe zinthu zilili komanso zochitika

Masiku ano, ma TV a kinescope sali ofunikira. Kuphatikiza pa kutha kwa makhalidwe abwino, apeza udindo wovulaza kwambiri thanzi la maso ndipo sakuyenera kuwonera nthawi yaitali. Komabe, chipangizo choterocho ndi choyenera kugula ngati:

1. Bajeti yogulira kwenikweni ndi organic . Zida zakale ndi zotsika mtengo kuposa zitsanzo zamakono, ngati mtengo suli wokwera mtengo ndi wogulitsa.
2. TV idzakhala chipangizo chachiwiri : mwachitsanzo, ngati eni ake akufuna kugula TV yachiwiri ya chipinda china kapena kukhala ndi njira yosungira ngati chizindikiro chachikulu kapena chofooka chikusweka (mwachitsanzo, palibe intaneti).
3. Kuwonera kwa nthawi yayitali sikukonzedwa : wailesi yakanema yataya kufunikira kwake, mapulogalamu akusonkhanitsa owonera ochepa komanso ochepera.
4. Zida zimagulidwa kuti zisangalatse kwakanthawi kapena kunja kwa mizinda : kwa nyumba ya dziko, khitchini ya chilimwe, kuyang’ana mpaka kukonzanso kwathunthu ndi bungwe la nyumbayo.

Mtengo wa CRT kinescopes ndi wotsika kwambiri kuposa mapanelo a BUS LSD[/ mawu]

Zosangalatsa! Ma kinescopes amagulidwa kuti azichita zinthu zina: kuchotsa zitsulo zopanda chitsulo, kugulitsanso, kupeza zida zosinthira.

Ndizovuta kutchula mtengo weniweni womwe uyenera kulipira pa TV yotereyi. Komabe, pogula, munthu ayenera kukumbukira kusagwirizana kwa makhalidwe ndi luso la zipangizo zoterezi. Poyerekeza ndi ma TV amakono, ma kinescopes ayenera kutsika kangapo, mkati mwa ma ruble masauzande angapo. Simuyenera kulipira mopitilira muyeso pogulanso: mtengo wokwera kwambiri sudzafanana ndi mtundu ndi magwiridwe antchito a chipangizocho.

Mavuto Wamba a CRT TV

Nthawi zambiri, eni ma TV a kinescope amakumana ndi zovuta monga:

• Kusakhazikika kwa dongosolo lamagetsi: mavuto ogwiritsira ntchito mphamvu, kuwononga ndalama zambiri.
• Kutentha kwambiri kwa mlandu ndi mbali za chipangizocho.
• Kuwonongeka kowoneka kwa magawo: kupanga mwaye, kutayikira kwa zinthu zogwirira ntchito.
• Mavuto amtundu wa siginecha.
• Kulephera kulumikizana ndi maukonde ena.
• Kuyatsa ndi kuzimitsa mosasamala, kulephera kudziwongolera paokha.

Kusokoneza kwa CRT TV ndikwachilendo mu 2022[/caption]

Zifukwa za mavuto ndi machiritso

Mtundu uliwonse wa zolakwika umafuna njira yapadera. Pakakhala zovuta zamphamvu kapena kutayikira kwa electrolyte, ma capacitors ayenera kusinthidwa: amakhala ndi moyo wocheperako.

Zofunika! Mukamagwira ntchito ndi electrolyte ndi capacitors, tsatirani njira zodzitetezera kapena funsani katswiri. Zinthu zamphamvu zamagetsi zimaphulika.

Mavuto ambiri ndi zipangizo zamagetsi amayamba chifukwa cha kutentha kwambiri. Zimakhudza dongosolo lonse ndi ziwalo zake. Pa ntchito mosalekeza, pali katundu wamphamvu pa kutchinjiriza, ma LED ndi capacitors. Ngati zigawo zikuluzikulu zitenthedwa, TV ikhoza kuzimitsa ndi phokoso la khalidwe ndikuyambiranso ntchito pambuyo pozizira. Pofuna kupewa kutenthedwa ndi kuwonongeka kwa mbali zina, muyenera kuyeretsa nthawi zonse ku fumbi. Fumbi ndilo chifukwa cha kutsekedwa kwa kukhudzana ndi kusokonezeka kwa kukhazikika kwa matabwa. Muyeneranso kuyang’anira kusowa kwa chinyezi pamalo omwe TV ili. Ngati khalidwe la fano kapena mphamvu ya chizindikiro ikuvutika, chifukwa chake chiyenera kufunidwa polumikizana ndi kufalitsa kudzera mu mlongoti kapena chingwe. Kwa zitsanzo zamtsogolo za CRT TV, mutha kukhazikitsa mapulogalamu apadera omwe amawongolera kuchuluka kwa ma sigino.

Zofunika! Ngati kulephera kugwira ntchito kwa CRT TV kumawonedwa, kuyezetsa kuyenera kuchitika osati pazida zazikulu zokha, komanso zida zothandizira. Ndikofunikira kuyeretsa gulu lowongolera nthawi zonse, kusintha mabatire, kuyang’ana kukhulupirika kwa zingwe ndi machitidwe ena olumikizira mapulogalamu.

Popanda luso loyenera, tikulimbikitsidwa kuti tilankhule ndi mbuye kuti tipewe mavuto ndi kukonza.
