TV Repair maoko avo - zvinobvira?

Pari, kusarudza mabhuku panyaya "TV Repair maoko avo" iri rakakura. Mukuwedzera, Internet inogona kuwana Tutorials kana emirayiridzo panyaya.

Hatigoni kuita kugadzira LCD TVs nemaoko avo, unofanira vamwe ruzivo mune zvemagetsi. Zvakakosha kubvisa chinhu kuti anogona kukanganisa kuchengeteka kwako uye vakachengeteka vaunoda.

TV neimwe ine maitiro ayo, izvo zvinokosha zvakagadzirwa kwayo. Naizvozvo, nzira kuti mhosva kuwanikwa ndekwokuda nomumwe.

Sarudza nguva yakaonekwa dambudziko uye sei chinotaurwa. Dzimwe nguva dambudziko anogona midzi havaratidzi akaiswa connectors, wiring mhosva, wakatsemuka, zvipiriso kana chete wakaputsika chikamu.

Sei kugadzirisa TV pachako?

Dzokubvisa kuwana mhosva

To disposal zvinobvira mukati maminitsi, asi ivo vari nyore kuona. Chinangwa ino ndiko kutsanangura chirwere nzira ano TV michina.

Kutanga. ... Sei?

Where kutanga kugadzira materevhizheni nemaoko avo?

In avo ezvinhu, kana TV ndiye "akafa" panguva zvose, ndiko, kuti irege akatendeuka, zvakaoma chaizvo kuwana mhosva localization. Asi tinoda nekukurumidza kuwana mhosva kwamuka, uye ipapo mumwe, uye kuhupedza nokukurumidza sezvinobvira.

Kutanga yakachena TV. Tanga wachenesa casing, uye ipapo pechiso CRT uye mugamuchiri kadhi. Tiri kuzviita ane vacuum uye bhurasho. Abnormality anogona kuonekwa pakarepo, kana ukaona munhu charred resistors, capacitors kuzvimba, vakapisa-kunze chips transistors. Kana panguva rokuchenesa kinescope waunoona chena panzvimbo läpinäkyvä chinu, zvinoreva kurasikirwa Vacuum.

Ongorora simba zvitengeswa

Chinhu chokutanga kuongorora ndiyo kunyatsoshanda simba rive. How kuzviita? Kutanga patsanura mutoro uye batanidza chimwe incandescent rambi. Kana voltage iri mariri isingasviki 110 V, zvinonzi vakagumisa kuti simba zvitengeswa inoperable. Zvadaro tarisa transformer Unit, ipapo Sefa capacitor, uyo voltage anofanira vanenge 160 V. Mushure throttle voltage anoenda goho rwakazara. Zvakakodzera unsolder kachidza kana fiyuzi pakudaro nokuzviparadzanisa simba romugove kubva mutsetse scan. The Simulator mitoro zvinonyorwa incandescent rambi, iyo hwakabatana mu kufanana capacitor.

Kana mhosva iri audited maatomu akafanana, mumwe filament rambi voltage anodonhedza. Saizvozvowo tarisa Sefa capacitor, chiyamuro mumatunhu, uye pemambure rectifier transistor. Kana incandescent chiedza girobhu racho Anovhura uye kure, kana zvichaita kudzima magetsi, simba rive riri kunge chakaremara. Saka vabatisise macheki pasina kushandisa incandescent Mabumba.

Zvadaro uyere voltage mhiri mutoro kana simba zvitengeswa Network. Kana ari voltage rinopfuura 130-150 B, zvinofanira akatumwa zvikuru chikwata redunhu. Ona capacitance. Kana kuita shoma, asi voltage achava kupfuura nzvimbo ukoshi. Mukupesana, kana voltage dererei pane dzose, tarisa redunhu yechipiri. Saka uri nzira yako kuita yokugadzirisa terevhizheni nemaoko ake pachake.

Danho rinotevera - chinjikira Check

Kana simba rive riri OK, tarisa goho pavaipfuura mutsetse Ongororo achishandisa incandescent rambi. Kana goho pachikuva riri chakaremara, chichagamuchirwa kuchengetwa zvose zvimwechetezvo sezvo rambi - ichava chiedza vaneta kana Anovhura uye kure.
Transistor chakakodzera vachiongorora chete kana, kana mwenje uzere uye kuzodzimwa. Kana zviri OK, uye voltage yakaderera, nechokwadi chokuti kudzorwa pulses pakarepo. Kana mwenje uye asingauyi kubuda uye chikwata rikasauya mberi, nyaya iri zvichida dzakaderera Coils. Edza nokuzviparadzanisa ari coils uye batidza TV. Kana Rinowanikwawo, zvino dambudziko inofanira kutsvaka munyika Kutsauka mugadziriro. Rwomuranda mhosva Kutsauka hurongwa ungavapa aine basa. Panyaya iyi, TV Anovhura kwenguva pfupi nguva, kuti arege kupisa kinescope.

The pfungwa pamatanda Ongororo

Kana ukaona chinjikira banding, mutsetse kushanda pakuvheneka muhurongwa. Dambudziko anofanira kutsvaka mune vashandi. Chokutanga, tarisa goho pachikuva uye gwenya remagetsi. Kana voltage wavo idukusa 24, ipapo mhaka mhosva kuti kuwanikwa mazviri. Kana chidzivaidzo kana Kuparara kuti rectifier diode anofanira kutsiva vainyeperwa Coil pabasa.

Ongorora simba romugove kutenderera pamufananidzo chubhu

Kana chidzitiro asingadi jekesa kana zvakakodzera kushanda pakuvheneka chikwata uye simba romugove, tarisa kuvimbika mufananidzo chubhu filament mutsvuku. Zvichida clippings anogona kubviswa tichibatsirwa chisimbiso.

Chii chinofanira kutarisa kwemhosva dambudziko?

Kana pasina mufananidzo, hapana ruzha, dambudziko iri kazhinji ari redhiyo chiteshi. Kana pasina mufananidzo, asi pane chikonzero anofanira kutsvaka ruvara chinogumbura kana vhidhiyo gudzazwi. Kana inzwi asi hapana mufananidzo, chikonzero ndiye yakaderera-kakawanda gudzazwi kana vhidhiyo. Kana kuno kuunga uye nomufananidzo, tsvaka kuti chikonzero ari tuner kana ayo muridzo unoridzirwa.

Cherechedzai inofanira kubhadharwa kudzora chikwata. Kuti mumuedze izvozvo, shandisa bhuku data, kana schema processor. Vanogona kutorwa kubva mugadziri wacho Website.

Nyaya ino ine chete chiduku chikamu zvikanganiso zvinogona kugadziriswa tisingatungamirirwi.

TV Repair nemaoko enyu haasi richizvitenda uye mutoro. Uye kana iwe nokusingaperi kumbopikisa kuti pakarepo kuti zvichava kuchiita pachako, tsvaka rubatsiro rwavanachiremba.
