I-CRT noma i-CRT TV – isabelomali kanye nenketho yokusebenza (hhayi njalo)

I-CRT noma i-kinescope TV iyi-TV esebenzisa ishubhu le-cathode ray (CRT) noma i-CRT (i-Cathode Ray Tube) ukuze ibonise isithombe. Ama-CRT noma ama-CRT TV abizwa ngokuthi amathelevishini asakaza izithombe kusetshenziswa amashubhu e-cathode ray, noma ama-kinescopes. Kwasetshenziswa imininingwane efanayo ezinguqulweni zokuqala zobuchwepheshe, ezakhiqizwa ekhulwini lama-20 kwaze kwaba yiminyaka eyiziro yaleli khulu leminyaka.

Kuyathakazelisa! Kubantu abavamile, ama-CRT TV abizwa ngokuthi “amadala” noma “isikwele” ngenxa yezinhlangano ezivamile.

Idivayisi nomgomo wokusebenza

Idivayisi ye-kinescopes ingachazwa kalula: ithubhu inezibhamu ezimbalwa ezakhelwe ngaphakathi, umbala ohambisana nohlelo lombala oluyinhloko (obomvu, obuluhlaza, obuhlaza okwesibhakabhaka). Ngesikhathi sokusebenza kwe-electron beam, izibhamu “zidubula” isikrini esimbozwe nge-phosphor, okubangela ukukhanya. Ukukhanya okwakha isithombe kusuka kumachashazi ngamanye.

Iqiniso! I-CRT wuhlobo lukamabonakude oludala kakhulu. Esikhathini sika-2022, abakhiqizi abaningi abakhiqizi imishini enjalo, noma kunjalo, amamodeli okuqala angatholakala kubanikazi-abathengisi.

Izinzuzo nezingozi ze-CRT

Ama-TV amadala anezinzuzo zawo:

• Uhlu olubanzi lwamamodeli ahlukene wokusebenza.
• Izintengo ezincane zemishini.
• Ubuchwepheshe bokusebenza obunokwethenjelwa ngokwanele, obuhlolwe isikhathi.
• Ukukhiqizwa kabusha kombala osontekile kancane kanye nezithombe zekhwalithi ephezulu ngisho nasezikrinini ezincane.
• Impilo ende yenkonzo (amanye amamodeli ayakwazi ukusebenza iminyaka eyi-15-25).

Kukhona futhi ukungalungi:

• Umkhawulo kasayizi wesikrini sezobuchwepheshe (cishe amayintshi angu-38).
• Ubukhulu obuphezulu, okufaka usayizi nesisindo se-TV.
• Ukuba khona kokuhlanekezela kwejometri, “ukuvutha”, izinkinga ngokugxila.
• Ukusalela okuphawulekayo kobuchwepheshe besimanje ukusebenza okulinganiselwe, ukungenzeki komsebenzi wekhwalithi ephezulu ngamadivayisi akamuva.

Qaphela! Ama-TV e-CRT abhekwa njengayingozi kakhulu ekuboneni: ngezinga lokuvuselela uhlaka ngaphansi kwe-100 Hertz, amehlo akhathala ngokushesha, ukusebenza ngokweqile kanye nekhanda elibuhlungu kungenzeka.

Indlela yokukhetha i-kinescope TV

Ukukhetha i-TV ye-kinescope engcono kakhulu, kufanele unake izici eziyinhloko:

1. Usayizi wesikrini olinganiselwe . Lapho ukhetha i-diagonal yedivayisi, kufanele unqume ukuthi izofakwa kuliphi igumbi. Emakamelweni amancane, ama-TV amancane afanelekile, ububanzi nobude, kufanele uthathe isikrini esikhulu.
2. Ubuchwepheshe obusetshenzisiwe . Ngokuyisisekelo, ubuchwepheshe be-kinescope bunezinga lokucwayiza kohlaka lwe-50 ne-100 Hertz. Ukuze uthole ukubuka okunethezekile kwesikhathi eside, kungcono ukhethe amadivaysi anemvamisa ephezulu.
3. Ifomethi yesikrini . Nikeza izikrini ezingu-4:3 no-16:9. Eyokuqala ifanele ukubuka izinhlelo ze-TV eziteshini zakudala – lena ifomethi irekhodi elinjalo. Ukuze ubuke ividiyo kumadiski noma amakhasethi, kufanele uthenge i-TV yesikrini esibanzi.
4. Uhlobo lwesipika . Kunamadivayisi anomsindo wokudlala we-mono nowe-stereo. Uma umthombo wokurekhoda ungenandaba, idivayisi enomsindo we-mono izokwenza. Izipikha ze-stereo zidlulisa isiqondiso somsindo kangcono. Kufanele futhi unake imodeli nekhwalithi yesipika: umsindo owengeziwe ngesikhathi sokusebenza awufiseki.
5. Ukutholakala kwemishini eyengeziwe nezinhlelo . Ama-TV amadala angathuthukiswa abe nezici zamamodeli ajwayelekile esimanje.
6. Ubukhona noma inombolo yezixhumi zemishini yangaphandle . Uma uhlela ukuxhuma amadivaysi engeziwe, kufanele ukhethe ama-TV anezixhumi ezifanele.
7. Ukuba khona kwezinkinobho zokulawula kuphaneli yangaphandle . I-TV ingahlonywa ngazo zombili izinkinobho eziyisisekelo kanye nesethi yonke yezilawuli kude. Inketho yokugcina yenza idivayisi ibe nzima kakhulu.

Kubiza malini ukuthenga i-TV ye-kinescope nokuthi yiziphi izimo nezimo

Ezikhathini zanamuhla, ama-TV e-kinescope awabalulekile. Ngaphezu kokuphelelwa yisikhathi kokuziphatha, bathole isimo sokulimaza kakhulu impilo yamehlo futhi abafanele ukubukwa isikhathi eside. Nokho, idivayisi enjalo kufanelekile ukuthenga uma:

1. Isabelomali sokuthenga empeleni singokwemvelo . Imishini endala ishibhile kunamamodeli anamuhla, uma intengo ingekho ngaphezulu komdayisi.
2. I-TV izoba yidivayisi yesibili : isibonelo, uma abanikazi befuna ukuthenga i-TV yesibili yelinye igumbi noma benenketho yokwenza isipele uma kwenzeka isignali eyinhloko noma ebuthakathaka iphuka (ngokwesibonelo, ingekho i-inthanethi).
3. Ukubuka isikhathi eside akuhleliwe : umabonakude ulahlekelwe ukubaluleka kwawo, izinhlelo ziqoqa ababukeli abambalwa abavamile.
4. Imishini ithengwa ukuzijabulisa kwesikhashana noma ngaphandle kwezimo zasemadolobheni : yendlu yezwe, ikhishi lasehlobo, ukubuka kuze kube yilapho ukulungiswa okuphelele nokuhlelwa kwekhaya.

Inani lama-kinescopes e-CRT liphansi ngokungenakuqhathaniswa kunamaphaneli e-BUS LSD[/caption]

Kuyathakazelisa! Ama-kinescopes athengelwa imisebenzi ethile: ukukhishwa kwensimbi engeyona insimbi, ukuthengiswa kabusha okulandelayo, ukuthola izingxenye eziyisipele ezingavamile.

Kunzima ukusho inani eliqondile okufanele likhokhelwe i-TV enjalo. Kodwa-ke, lapho uthenga, umuntu kufanele akhumbule ukungahloniphi kokuziphatha nezobuchwepheshe kwemishini enjalo. Uma kuqhathaniswa nama-TV esimanje, ama-kinescopes kufanele abize kancane izikhathi ezimbalwa, ngaphakathi kwama-ruble ayizinkulungwane ezimbalwa. Akufanele ukhokhe ngokweqile uma uthenga kabusha: intengo enenani elingaphezulu ngeke ifane nekhwalithi nokusebenza kocingo. Yini ewusizo kumaphaneli amadala we-CRT TV: https://youtu.be/Eg-tx_uE3Pg

Izinkinga Ezivamile ze-CRT TV

Imvamisa, abanikazi be-kinescope TV babhekene nokuwohloka okufana nalokhu:

• Ukungazinzi kwesistimu yamandla: izinkinga ngokusetshenziswa kwamandla, ukusebenzisa imali ngokweqile.
• Ukushisa ngokweqile kwekesi nezingxenye zedivayisi.
• Ukulimala okubonakalayo ezingxenyeni: ukwakheka kwe-soot, ukuvuza kwezinto zokusebenza.
• Izinkinga zekhwalithi yesiginali.
• Ukungakwazi ukuxhuma kumanethiwekhi athile.
• Ukuvula nokuvala ngokuzenzakalelayo, ukungakwazi ukulawula amamodi ngokuzimela.

Izinkinga nezixazululo

Uhlobo ngalunye lwephutha ludinga indlela ekhethekile. Uma
kwenzeka izinkinga zamandla noma ukuvuza kwe-electrolyte, ama- capacitor kufanele ashintshwe: anempilo elinganiselwe.

Okubalulekile! Uma usebenza nge-electrolyte nama-capacitor, landela izinyathelo zokuphepha noma uxhumane nochwepheshe. Izinto zesistimu yamandla ziyaqhuma.

Izinkinga eziningi ngemishini zibangelwa ukushisa ngokweqile. Kuthinta kokubili uhlelo lonke kanye nezingxenye zalo ngazinye. Ngesikhathi sokusebenza okuqhubekayo, kunomthwalo oqinile ku-insulation, ama-LED nama-capacitor. Uma izingxenye eziyinhloko zishisa ngokweqile, i-TV ingase ivalwe ngomsindo wesici futhi iqalise ukusebenza ngemva kokuphola. Ukuze uvimbele ukushisa nokulimala kwezinye izingxenye, kufanele uhlanze njalo icala othulini. Uthuli luyimbangela yokuvalwa kokuxhumana nokuphazamiseka kokuzinza kwamabhodi. Udinga futhi ukuqapha ukungabikho komswakama endaweni lapho i-TV ikhona. Uma
ikhwalithi yesithombe noma amandla esignali ehlupheka, imbangela kufanele ifunwe ekuxhumekeni kokudlulisela nge-antenna noma ikhebula. Kumamodeli akamuva ama-CRT TV, ungafaka izinhlelo ezikhethekile ezithuthukisa izinga lesiginali.

Okubalulekile! Uma ukungasebenzi kahle kwe-CRT TV kubonakala, ukuxilonga akufanele kwenziwe kuphela ngemishini eyinhloko, kodwa futhi nemishini yokusiza. Kuyadingeka ukuhlanza njalo iphaneli yokulawula, ukushintsha amabhethri, ukuhlola ubuqotho bezintambo nezinye izinhlelo zokuxhuma ezinhlelweni.

Uma kungabikho amakhono afanele, kunconywa ukuthi uxhumane nenkosi ukuze ugweme izinkinga ngokulungisa.
