CRT kana CRT TV – bhajeti uye sarudzo yekushanda (kwete nguva dzose)

A CRT kana kinescope TV iTV inoshandisa cathode ray chubhu (CRT) kana CRT (Cathode Ray Tube) kuratidza mufananidzo. MaTV eCRT kana CRT anodaidzwa kunzi terevhizheni anofambisa mifananidzo achishandisa cathode ray chubhu, kana kinescopes. Tsanangudzo yakafanana yakashandiswa mushanduro dzokutanga dzeruzivo rwokugadzira zvinhu, dzakabudiswa muzana ramakore rechi20 kusvikira kumakore a zero ezana rino ramakore.

Inonakidza! Muvanhuwo zvavo, CRT TVs inonzi “yekare” kana “square” nekuda kwekushamwaridzana kwakafanana.

Chigadzirwa uye nheyo yekushanda

Chishandiso chekinescopes chinogona kutsanangurwa zviri nyore: iyo chubhu ine akati wandei akavakirwa-mupfuti, iyo ruvara runoenderana neiyo huru color scheme (tsvuku, girini, bhuruu). Panguva yekushanda kwe electron beam, pfuti “inopfura” chidzitiro chakavharwa ne phosphor, iyo inokonzera kupenya. Icho chiedza chinoumba mufananidzo kubva kune ega madotsi.

Chokwadi! CRT ndiyo mhando yekare yeterevhizheni. Kwenguva ye2022, vagadziri vazhinji havagadziri michina yakadaro, zvisinei, mamodheru ekutanga anogona kuwanikwa kubva kumuridzi-vatengesi.

Zvakanakira uye zvakaipa zveCRT

MaTV ekare ane zvakanakira:

• Mhando yakawanda yemhando dzakasiyana dzekushanda.
• Mitengo midiki yemidziyo.
• Zvakakwana zvakavimbika, nguva-yakaedzwa kushanda tekinoroji.
• Zvishoma zvakakanganiswa kubereka kwemavara uye mifananidzo yemhando yepamusoro kunyangwe padiki skrini.
• Hupenyu hurefu hwebasa (mamwe mamodheru anokwanisa kushanda makore 15-25).

Panewo zvakaipira:

• Tekinoroji skrini saizi kuganhurira (inenge 38 inches).
• Zviyero zvepamusoro, kusanganisira ukuru uye uremu hweTV.
• Kuvapo kwekukanganisa kwejometri, “flare”, matambudziko nekutarisa.
• Kusarira kwakakosha kuseri kwetekinoroji yemazuva ano kune mashoma mashandiro, kusagoneka kwebasa remhando yepamusoro nemidziyo yazvino.

Attention! MaTV eCRT anoonekwa seane njodzi zvakanyanya pakuona: pachiyero chekuzorodza pazasi pe100 Hertz, maziso anoneta nekukurumidza, kushanda zvakanyanya uye misoro inogona kuitika.

Nzira yekusarudza kinescope TV

Kuti usarudze yakanakisa kinescope TV, unofanirwa kutarisisa kune iwo makuru maitiro:

1. Saizi yakaenzana yechidzitiro . Paunosarudza diagonal yemudziyo, iwe unofanirwa kusarudza mukamuri iyo ichaiswa. Kune makamuri madiki, maTV madiki akakodzera, kune yakakura uye yakareba, iwe unofanirwa kutora yakakura skrini.
2. Technology inoshandiswa . Chaizvoizvo, tekinoroji yekinescope ine furemu flicker rate ye50 uye 100 Hertz. Kuti ugare wakasununguka kutarisa kwenguva refu, zviri nani kusarudza michina yakakwira-frequency.
3. Screen Format . Govera 4:3 uye 16:9 skrini. Yekutanga yakakodzera kuona TV inoratidza pazviteshi zvekare – iyi ndiyo fomati ine rekodhi rakadaro. Kuti uone vhidhiyo kubva kumadhisiki kana makaseti, unofanira kutenga TV ine sikirini yakakura.
4. Mutauriri rudzi . Kune zvishandiso zvine mono uye stereo ruzha rwekutamba. Kana chinyorwa chekurekodha chisina basa, mudziyo une mono sound uchaita. Vatauri veStereo vanoburitsa gwara reruzha zviri nani. Iwe unofanirwawo kuterera kune modhi uye mhando yemukurukuri: yakawedzera ruzha panguva yekushanda haidiwe.
5. Kuwanikwa kwezvimwe zvishandiso uye zvirongwa . MaTV ekare anogona kuvandudzwa nemhando dzemhando dzemazuva ano.
6. Kuvapo kana nhamba yezvibatanidza zvemidziyo yekunze . Kana ukaronga kubatanidza mamwe madivayiri, iwe unofanirwa kusarudza maTV ane majoini akakodzera.
7. Kuvepo kwemabhatani ekudzora pane yekunze panel . Iyo TV inogona kuve yakashongedzerwa nemabhatani ekutanga uye seti yese yezvinodzora kure. Iyo yekupedzisira sarudzo inoita kuti mudziyo uwedzere kunetsa.

Zvinoita marii kutenga kinescope TV uye nemamiriro api uye mamiriro ezvinhu

Munguva dzazvino, kinescope TV haina basa. Mukuwedzera pakuparara kwetsika, vakawana mamiriro ekunyanya kukuvadza kune hutano hwemaziso uye haana kukodzera kutarisa kwenguva refu. Nekudaro, mudziyo wakadaro wakakodzera kutenga kana:

1. Iyo bhajeti yekutenga ndeye organic . Zvishandiso zvekare zvakachipa kupfuura zvidhori zvemazuva ano, kana mutengo wacho usingawedzereki nemutengesi.
2. Iyo TV ichava yechipiri mudziyo : semuenzaniso, kana varidzi vachida kutenga yechipiri TV kune imwe kamuri kana kuve neiyo backup sarudzo kana iyo huru kana isina simba chiratidzo chinoputsika (somuenzaniso, pasina Internet).
3. Kuona kwenguva refu hakuna kurongwa : terevhizheni yakarasa kukosha kwayo, mapurogiramu ari kuunganidza vashoma uye vashoma vanoonekwa nguva dzose.
4. Zvishandiso zvinotengwa zvekuvaraidza kwenguva pfupi kana kunze kwemamiriro emuguta : yeimba yenyika, kicheni yezhizha, kutarisa kusvikira kugadziriswa kwakakwana uye kurongeka kweimba.

Inonakidza! Kinescopes inotengwa kune chaiyo zviitiko: kudhirowa kwesimbi isina-ferrous, kunotevera kutengeswa, kuwana zvisingawanzo spare parts.

Zvakaoma kutumidza mutengo chaiwo wakakodzera kubhadhara kune yakadaro TV. Nekudaro, kana uchitenga, munhu anofanirwa kuyeuka kusakosha kwehunhu uye kwehunyanzvi hwemidziyo yakadaro. Mukuenzanisa nemazuva ano maTV, kinescopes inofanira kudhura kakawanda zvishoma, mukati mezviuru zvishoma zveRubles. Iwe haufanirwe kubhadhara zvakanyanya paunenge uchitengazve: mutengo wakawandisa hauenderane nemhando uye kushanda kwechigadzirwa.

Zvakajairwa CRT TV Matambudziko

Kazhinji kazhinji, varidzi vekinescope TV vanotarisana nekuputsika kwakadai se:

• Kusagadzikana kwesimba remagetsi: matambudziko nekushandiswa kwesimba, kunyanya kushandisa.
• Kupisa kwakanyanya kwekesi uye zvikamu zvechigadzirwa.
• Kukuvadza kunoonekwa kune zvikamu: kuumbwa kwe soot, kubuda kwezvinhu zvinoshanda.
• Signal quality matambudziko.
• Kusakwanisa kubatanidza kune mamwe manetwork.
• Involuntary switching on and off, kusakwanisa kuzvimiririra kudzora modes.

Zvikonzero zvematambudziko nekugadzirisa

Mhando yega yega yekukanganisa inoda nzira yakakosha. Muchiitiko chematambudziko emagetsi kana kubuda kwe electrolyte, ma capacitors anofanira kutsiviwa: ane hupenyu hushoma.

Zvakakosha! Paunenge uchishanda ne electrolyte uye capacitors, tevera matanho ekuchengetedza kana kubata nyanzvi. Zvinhu zvesimba remagetsi zvinoputika.

Matambudziko mazhinji nemidziyo yemagetsi anokonzerwa nekupisa. Inobata zvose hurongwa hwose uye zvikamu zvayo zvega. Munguva yekuenderera mberi kwekushanda, kune mutoro wakasimba pane kuvhara, LEDs uye capacitors. Kana zvinhu zvikuru zvikapisa, TV inogona kudzima neruzha rwehunhu yotangazve kuvhiya mushure mekutonhora. Kuti udzivise kupisa uye kukanganisa kune zvimwe zvikamu, unofanira kugara uchichenesa nyaya yacho kubva muguruva. Dust ndiyo inokonzera kuvharwa kwekubatana uye kukanganisa kwekugadzikana kwemapuranga. Iwe zvakare unofanirwa kutarisa kusavapo kwehunyoro munzvimbo iyo TV iri. Kana chimiro chemufananidzo kana simba rechiratidzo chichitambura, chikonzero chinofanirwa kutsvakwa mukubatanidza kune kutapurirana kuburikidza neantenna kana tambo. Kune gare gare modhi yeCRT TVs, unogona kuisa akakosha mapurogiramu anovandudza chiyero chechiratidzo.

Zvakakosha! Kana kukanganisa mukushanda kweCRT TV kuchionekwa, kuongororwa kunofanira kuitwa kwete chete kune midziyo huru, asiwo yekubatsira midziyo. Izvo zvinodikanwa kugara uchichenesa control panel, kushandura mabhatiri, tarisa kutendeseka kwetambo uye mamwe masisitimu ekubatanidza kune zvirongwa.

Mukusavapo kweunyanzvi hwakakodzera, zvinokurudzirwa kuonana natenzi kuti udzivise matambudziko nekugadzirisa.
