CHENJEZO
Chidziwitso cha disassemblychi chapangidwira akatswiri odziwa kukonza okha ndipo sichinapangidwe kuti chigwiritsidwe ntchito ndi anthu wamba. Lilibe machenjezo kapena chenjezo lolangiza anthu omwe si aukadaulo za zoopsa zomwe zingachitike poyesa kugwiritsa ntchito chinthu. Zinthu zoyendetsedwa ndi magetsi ziyenera kutumizidwa kapena kukonzedwa ndi akatswiri odziwa ntchito. Kuyesa kulikonse kothandizira kapena kukonza zomwe zaperekedwa ndi wina aliyense pazavutoli zitha kuvulaza kapena kufa.

General Safety malangizo

 Malangizo Azambiri 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. Kutuluka Pakalipano Cold Check
2. Kutayikira Current Hot Check
3. Kupewa kwa Electro Static Discharge (ESD) kupita ku Electrostatic Sensitive

 Chidziwitso Chofunika

Tsatirani malamulo ndi machenjezo
Chofunikira kwambiri ndikulemba zowopsa zomwe zingachitike kapena chiwopsezo cha ogwira ntchito kuti atsegule mayunitsi ndikusokoneza mayunitsi. Za example, tikuyenera kufotokoza bwino momwe tingapewere kuthekera kwa kugwedezeka kwa magetsi kuchokera kumagetsi amoyo kapena zida zamagetsi zamagetsi (ngakhale magetsi azimitsidwa).

Samalani ndi kugwedezeka kwa magetsi
Kuti mupewe kuwonongeka komwe kungayambitse kugwedezeka kwamagetsi kapena moto, musawonetse TV iyi kumvula kapena chinyezi chambiri. TV imeneyi siyenera kuonetsedwa ndi madzi akudontha kapena kudontha, ndiponso zinthu zodzazidwa ndi madzi, monga miphika, siziyenera kuikidwa pamwamba kapena pamwamba pa TV.

Electro static discharge (ESD)
Zida zina za semiconductor (solid state) zitha kuonongeka mosavuta ndi magetsi osasunthika. Zigawo zotere zimatchedwa Electrostatically Sensitive (ES) Devices. Njira zotsatirazi ziyenera kugwiritsidwa ntchito pothandizira kuchepetsa kuwonongeka kwa chigawocho chifukwa cha electros static discharge (ESD).

Za lead free solder (PbF)
Mankhwalawa amapangidwa pogwiritsa ntchito solder wopanda kutsogolera ngati gawo la kayendetsedwe ka makampani ogula zinthu kuti azikhala ndi chilengedwe. Solder wopanda lead ayenera kugwiritsidwa ntchito pokonza ndi kukonza mankhwalawa.

Gwiritsani ntchito zopangira (zigawo zotchulidwa)
Magawo apadera omwe ali ndi zolinga za retardant moto (resistors), phokoso lapamwamba (capacitors), phokoso lochepa (resistors), etc. Mukasintha chilichonse mwazinthu, onetsetsani kuti mwangogwiritsa ntchito zida zomwe zawonetsedwa pamndandanda wamagawowo.

Yang'anani Chitetezo Pambuyo Kukonza
Tsimikizirani kuti zomangira, zigawo ndi mawaya omwe adachotsedwa kuti agwiritse ntchito ayikidwa pamalo oyamba, kapena ngati pali malo omwe asokonekera pozungulira malo omwe amathandizidwa kapena ayi. Yang'anani kutsekereza pakati pa chotengera cha mlongoti kapena chitsulo chakunja ndi mapulagi a zingwe za AC. Ndipo onetsetsani chitetezo cha izo.

General Servicing Precautions

1. Nthawi zonse chotsani chingwe chamagetsi cha AC cholandirira kuchokera kugwero lamagetsi la AC kale;
   • 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.
     CHENJEZO: Kulowetsa gawo molakwika kapena kuyika kolakwika kwa ma electrolytic capacitor kungayambitse ngozi ya kuphulika.
2. Yesani voltage pongoyeza ndi mphamvu yokwera yoyenereratage mita kapena voliyumu inatagchipangizo choyezera cha e (DVM, FETVOM, ndi zina) chokhala ndi volyumu yoyeneratagndi kufufuza.
   Osayesa kuchuluka kwamphamvutagndi "kujambula arc".
3. Osapopera mankhwala pafupi kapena pafupi ndi cholandirirachi kapena pagulu lililonse.
4. Osagonjetsa pulagi/socket B+ voltagma interlocks omwe olandila omwe ali ndi bukuli atha kukhala ndi zida.
5. Osagwiritsa ntchito mphamvu ya AC pachida ichi ndi/kapena
6. Nthawi zonse gwirizanitsani malo olandirira oyesa ku malo olandirira chassis musanalumikize wolandila woyezetsa kutsogolo.
   Nthawi zonse chotsani olandila mayeso omaliza. Ma capacitors angayambitse ngozi ya kuphulika.
7. Gwiritsani ntchito ndi wolandila uyu zokha zoyeserera zomwe zafotokozedwa m'bukuli.
   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.

Zida zamagetsi (ES)
Zida zina za semiconductor (solid-state) zitha kuonongeka mosavuta ndi magetsi osasunthika. Zigawo zotere zimatchedwa Electrostatically Sensitive (ES) Devices. Eksampzida zamtundu wa ES ndi mabwalo ophatikizika ndi ma transistors ochita kumunda ndi zida za semiconductor "chip". Njira zotsatirazi ziyenera kugwiritsidwa ntchito pothandizira kuchepetsa kuwonongeka kwa chigawo chomwe chimayambitsidwa ndi static ndi static magetsi.

1. Musanayambe kugwira gawo lililonse la semiconductor kapena semiconductor- equipped, chotsani mphamvu iliyonse yamagetsi pathupi lanu pokhudza nthaka yomwe imadziwika. Kapenanso, pezani ndi kuvala chida chogulitsira chapamanja chomwe chilipo pamalonda, chomwe chiyenera kuchotsedwa kuti mupewe zifukwa zododometsa musanagwiritse ntchito mphamvu pagawo loyesedwa.
2. Mukachotsa gulu lamagetsi lomwe lili ndi zida za ES, ikani msonkhanowo pamalo opangira zinthu monga chojambula cha aluminiyamu, kuti mupewe kuchuluka kwa ma electrostatic charge kapena kuwonekera kwa msonkhanowo.
3. Gwiritsani ntchito chitsulo chokhazikika chokhazikika pazida za solder kapena unsolder ES.
4. Gwiritsani ntchito chida chochotseratu anti-static mtundu wa solder. Zida zina zochotsera solder zomwe sizinatchulidwe kuti YantistaticY zimatha kupanga ndalama zamagetsi zokwanira kuwononga zida za ES.
5. Musagwiritse ntchito mankhwala opangidwa ndi freon-propelled. Izi zitha kupanga ndalama zamagetsi zokwanira kuwononga zida za ES.
6. Osachotsa chipangizo cha ES cholowa m'malo mwake pagulu lake lodzitchinjiriza mpaka nthawi yomweyo musanayambe kuyika. (Zida zambiri zolowa m'malo mwa ES zimapakidwa ndi zowongolera zamagetsi zofupikitsidwa ndi thovu loyendetsa, zojambulazo za aluminiyamu kapena zinthu zofananira).
7. Musanayambe kuchotsa zinthu zodzitchinjiriza pazitsogozo za chipangizo cha ES cholowa m'malo, gwirani zinthu zoteteza ku chassis kapena msonkhano wadera momwe chipangizocho chidzayikidwira.
   CAUTION: Be sure no power is applied to the chassis or circuit, and observe all other safety precautions.
8. Chepetsani kusuntha kwa thupi pogwira zida za ES zosapakidwa. (Kupanda kutero kuyenda kopanda vuto monga kupukuta pamodzi kwa nsalu zanu kapena kukweza phazi lanu kuchoka pa kapeti Qoor kumatha kupanga magetsi osasunthika okwanira kuwononga chipangizo cha ES.)
