I-AOC 27E4U LCD Monitor

ISEXWAYISO
Lolu lwazi lokuqaqa lwenzelwe ochwepheshe abanolwazi lokulungisa kuphela futhi alwakhelwe ukusetshenziswa umphakathi jikelele. Ayiqukethe izexwayiso noma izexwayiso zokwazisa abantu okungebona abezobuchwepheshe ngezingozi ezingaba khona ekuzameni ukusevisa umkhiqizo. Imikhiqizo esebenza ngogesi kufanele inikezwe isevisi noma ilungiswe kuphela ochwepheshe abanolwazi. Noma yimuphi umzamo wokwenza isevisi noma ukulungisa umkhiqizo noma imikhiqizo okukhulunywa ngayo kulokhu kwaziswa kokuhlakazwa yinoma ubani omunye kungaholela ekulimaleni okubi kakhulu noma ukufa.

Imiyalelo Yezokuphepha Ejwayelekile

 Iziqondiso Ezijwayelekile When servicing, observe the original lead dress. If a short circuit is found, replace all parts which have  been overheated or damaged by the short circuit.  After servicing, see to it that all the protective devices such as insulation barriers, insulation papers shields are properly installed.  After servicing, make the following leakage current checks to prevent the customer from being exposed to shock hazards.

1. Ukuvuza Ukuhlola Okubandayo Kwamanje
2. Ukuvuza Ukuhlola Okushisayo Kwamanje
3. Ukuvinjelwa Kokukhishwa Kwe-Electro Static (ESD) Kuze Kuzwele Ngokwe-Electrostatic

 Isaziso Esibalulekile

Landela imithetho nezixwayiso
Okubaluleke kakhulu ukuklelisa ubungozi obungaba khona noma ubungozi kubasebenzi besevisi ukuthi bavule amayunithi futhi bahlukanise amayunithi. Okwesiboneloample, sidinga ukuchaza kahle ukuthi singakugwema kanjani ukuba nokwenzeka kokuthola ukushaqeka kukagesi esiphakelini samandla esibukhoma noma izingxenye zikagesi ezishajiwe (ngisho namandla avaliwe).

Qaphela ukushaqeka kukagesi
Ukuze uvimbele umonakalo ongase ubangele ukushaqeka kukagesi noma umlilo, ungayivezi le sethi ye-TV emvuleni noma kumswakama oweqile. Le TV akumele ibekwe obala emanzini aconsayo noma achaphazayo, futhi izinto ezigcwele uketshezi, njengamavazi, akufanele zibekwe phezu noma ngaphezu kwe-TV.

I-Electro static discharge (ESD)
Amanye amadivaysi e-semiconductor (isimo esiqinile) angonakaliswa kalula ugesi ongashintshi. Izingxenye ezinjalo zivame ukubizwa ngokuthi Amadivayisi Azwela Nge-Electrostatic (ES). Amasu alandelayo kufanele asetshenziselwe ukusiza ukunciphisa izehlakalo zokulimala kwengxenye ebangelwa i-electros static discharge (ESD).

Mayelana ne-lead free solder (PbF)
Lo mkhiqizo ukhiqizwa kusetshenziswa i-solder engenamthofu njengengxenye yokunyakaza ngaphakathi kwemboni yemikhiqizo yabathengi ngokubanzi ukuze ube nesibopho semvelo. I-solder engenamthofu kufanele isetshenziswe ekuseviseni nasekulungiseni lo mkhiqizo.

Sebenzisa izingxenye zokukhiqiza (izingxenye ezishiwo)
Izingxenye ezikhethekile ezinezinjongo zokunqanda umlilo (iziphikisayo), umsindo wekhwalithi ephezulu (ama-capacitor), umsindo ophansi (ama-resistors), njll. Lapho ushintsha noma yiziphi izingxenye, qiniseka ukuthi usebenzisa izingxenye ezishiwo zomkhiqizi kuphela eziboniswe ohlwini lwezingxenye.

Ukuhlola Ukuphepha Ngemva Kokulungiswa
Qinisekisa ukuthi izikulufu, izingxenye kanye nezintambo ezikhishwe ukuze ziseviswe zibekwe endaweni yokuqala, noma ukuthi kukhona yini izindawo eziwohlokayo eduze kwezindawo ezinesevisi ezinikezwa isevisi noma cha. Hlola ukwahlukanisa phakathi kwetheminali ye-antenna noma insimbi yangaphandle nama-blade epulaki yentambo ye-AC. Futhi qiniseka ukuphepha kwalokho.

Izinyathelo Ezijwayelekile Zokusebenza

1. Njalo khipha isamukeli sentambo yamandla ye-AC kumthombo wamandla we-AC ngaphambili;
   • Removing or reinstalling any component, circuit board module or any other receiver assembly.
   • Disconnecting or reconnecting any receiver electrical plug or other electrical connection.
   • Connecting a test substitute in parallel with an electrolytic capacitor in the receiver.
     ISEXWAYISO: Ukushintsha ingxenye okungalungile noma ukufakwa kwe-polarity okungalungile kwama-capacitor e-electrolytic kungase kubangele ingozi yokuqhuma.
2. Hlola ivolumu ephezulutage kuphela ngokuyikala ngevolumu ephezulu efaneletagimitha ye-e noma enye ivolumutagidivayisi yokulinganisa ye-e (i-DVM, i-FETVOM, njll) ifakwe ivolumu ephezulu efanelekiletage phenya.
   Ungahloli ivolumu ephezulutage ngokuthi “ukudweba i-arc”.
3. Ungafafazi amakhemikhali kuso noma eduze kwalesi samukeli nanoma yiziphi izingxenye zaso.
4. Ungahluli noma iyiphi ipulaki/isokhethi B+ voltagama-e interlocks abangahlonyiswa ngawo abemukeli abafakwe kule manuwali yesevisi.
5. Ungasebenzisi amandla e-AC kuleli thuluzi kanye/noma i-
6. Njalo xhuma umthofu ophansi owamukela isivivinyo endaweni ye-chassis yomamukeli ngaphambi kokuxhuma umamukeli ohlolwayo oholayo.
   Ngaso sonke isikhathi susa okokugcina kokuthola umamukeli wokuhlola. Ama-Capacitor angase abangele ingozi yokuqhuma.
7. Sebenzisa nalesi samukeli kuphela izinto zokuhlola ezicaciswe kule manuwali yesevisi.
   CAUTION: Jo not connect the test fixture ground strap to any heat sink in this receiver.
8. Insulation resistance between the cord plug terminals and the eternal exposure metal should be more than  by using the 500V insulation resistance meter.

Amadivayisi Azwela Ngokwe-Electrostatic (ES).
Amanye amadivaysi e-semiconductor (solid-state) angonakaliswa kalula ugesi omile. Izingxenye ezinjalo zivame ukubizwa ngokuthi Amadivayisi Azwela Nge-Electrostatic (ES). ExampIzingxenye zemishini ye-ES ejwayelekile ziyiziyingi ezihlanganisiwe kanye namanye ama-transistors asebenza ensimini kanye nezingxenye ze-semiconductor "chip". Amasu alandelayo kufanele asetshenziselwe ukusiza ukunciphisa izehlakalo zokulimala kwengxenye ebangelwa ugesi ongashintshi.

1. Ngokushesha ngaphambi kokuphatha noma iyiphi ingxenye ye-semiconductor noma ukuhlanganiswa okufakwe i-semiconductor, khipha noma iyiphi inkokhiso ye-electrostatic emzimbeni wakho ngokuthinta umhlabathi owaziwayo. Kungenjalo, thola futhi ugqoke idivaysi yebhande lesihlakala elikhishwayo elitholakalayo elithengiswayo, okufanele lisuswe ukuze kuvinjwe izizathu zokushaqeka ezingaba khona ngaphambi kokufaka amandla kuyunithi ehlolwayo.
2. Ngemva kokukhipha umhlangano kagesi ofakwe amadivayisi we-ES, beka umhlangano endaweni eqhutshwayo njengephepha le-aluminium, ukuvimbela ukunqwabelana kwe-electrostatic charge noma ukuchayeka komhlangano.
3. Sebenzisa kuphela insimbi enethiphu egxiliwe ukuze uhlanganise noma ukhiphe amadivaysi e-ES.
4. Sebenzisa kuphela idivayisi yokususa i-solder yohlobo lwe-anti-static. Amanye amadivaysi okukhipha i-solder angahlukaniswa njenge-YantistaticY angakwazi ukukhiqiza amashaji kagesi anele ukulimaza amadivayisi e-ES.
5. Ungasebenzisi amakhemikhali e-freon-propelled. Lokhu kungenza amashaji kagesi anele ukulimaza amadivayisi e-ES.
6. Ungayisusi enye idivayisi ye-ES ephaketheni layo lokuvikela kuze kube ngokushesha ngaphambi kokuba ulungele ukuyifaka. (Iningi lamadivaysi e-ES ashintshwayo apakishwe ngomthofu ofinyezwe ngogesi ndawonye ngegwebu eliqhutshwayo, ucwecwe lwe-aluminium noma impahla yokuqhuba eqhathaniswayo).
7. Ngokushesha ngaphambi kokukhipha izinto zokuzivikela emithonjeni yedivayisi ye-ES esikhundleni, thinta okokuvikela ku-chassis noma umhlangano wesifunda lapho idivayisi izofakwa khona.
   CAUTION: Be sure no power is applied to the chassis or circuit, and observe all other safety precautions.
8. Nciphisa ukunyakaza komzimba lapho uphatha amadivayisi we-ES angapakishiwe. (Uma kungenjalo ukunyakaza okungenangozi njengokuxubha ndawonye kwendwangu yakho yezingubo noma ukuphakamisa unyawo lwakho ku-Qoor enokhaphethi kungakhiqiza ugesi omile owanele ukulimaza idivayisi ye-ES.)

Uku-oda izingxenye ezisele

Sicela ufake imininingwane elandelayo lapho u-oda izingxenye. (Ikakhulu uhlamvu lwenguqulo)

1. Inombolo yemodeli, inombolo ye-serial kanye nenguqulo yesofthiwe
   Inombolo yemodeli kanye nenombolo ye-Serial ingatholakala ngemuva komkhiqizo ngamunye futhi Inguqulo Yesofthiwe ingatholakala Ohlwini Lwezingxenye Ezisele.
2. Ingxenye Eyengeziwe No. kanye Nencazelo
   Ungazithola Ohlwini Lwezingxenye Ezisele

Isithombe esisetshenziswe kule manuwali
Umfanekiso nezithombe ezisetshenziswe kule Manuwali zingase zingasuki ekwakhiweni kokugcina kwemikhiqizo, okungase kwehluke emikhiqizweni yakho ngandlela thize.

Ungawufunda Kanjani Lo Myalelo

Ukusebenzisa Izithonjana:
Izithonjana zisetshenziselwa ukuheha ukunaka komfundi olwazini oluthile. Incazelo yesithonjana ngasinye ichazwe kuthebula elingezansi:

• Qaphela:
  “Inothi” linikeza ulwazi olungadingeki, kodwa nokho olungase lube wusizo kumfundi, njengamathiphu namasu.
• Isexwayiso:
  “Isixwayiso” sisetshenziswa uma kunobungozi bokuthi umfundi, ngokukhohlisa okungalungile, angase alimaze amathuluzi, alahle idatha, athole umphumela ongalindelekile noma aqale kabusha(ingxenye) yenqubo.
• Isexwayiso:
  “Isexwayiso” sisetshenziswa uma kunengozi yokulimala komuntu.
• Ireferensi:
  “Ireferensi” iqondisa umfundi kwezinye izindawo kulo mbhalo noma kule manuwali, lapho ezothola khona ulwazi olwengeziwe ngesihloko esithile.
