<\/a>Probl\u00e9my s obrazovkou telev\u00edzora Samsung<\/strong><\/h2>\n\n\n\n

Mimochodom, Samsung v minulosti pou\u017e\u00edval obrazovky od mnoh\u00fdch v\u00fdrobcov, hoci a\u017e do predaja vlastnej tov\u00e1rne na LED obrazovky v roku 2021 bola v\u00e4\u010d\u0161ina obrazoviek vyroben\u00e1 interne. Rozpo\u010dtov\u00e9 s\u00e9rie, konkr\u00e9tne RU, QR-2019, TU, QT-2020 a AU-2021, <\/strong>pritiahli zna\u010dn\u00fa pozornos\u0165 kv\u00f4li opakuj\u00facim sa probl\u00e9mom s obrazovkou. Absencia ultra-rozpo\u010dtov\u00e9ho radu BU TV v USA v roku 2022 vyvolala ot\u00e1zky a najnov\u0161ie inform\u00e1cie nazna\u010duj\u00fa, \u017ee rozsah t\u00fdchto probl\u00e9mov viedol k ukon\u010deniu v\u00fdroby a predaja super-rozpo\u010dtov\u00fdch telev\u00edzorov Samsung v niektor\u00fdch regi\u00f3noch.<\/p>\n\n\n\n

V t\u00fdchto TV riadkoch boli identifikovan\u00e9 dve pozoruhodn\u00e9 chyby s\u00favisiace s obrazovkou:<\/p>\n\n\n\n

    \n
  1. Zlyhanie podsvietenia: <\/strong>Tento probl\u00e9m sp\u00f4sobil prehriatie obrazovky, \u010d\u00edm sa stala nepou\u017eite\u013en\u00e1. Podrobn\u00fd popis tohto probl\u00e9mu n\u00e1jdete v \u010dl\u00e1nku \u201c Moja TV obrazovka sa ve\u013emi zahrieva. <\/a>\u201c<\/li>\n\n\n\n
  2. Pruhy: <\/strong>Na telev\u00edznej obrazovke sa objavuj\u00fa horizont\u00e1lne aj vertik\u00e1lne pruhy, \u010dasto naz\u00fdvan\u00e9 zlomen\u00e9 pixely.<\/li>\n<\/ol>\n\n\n\n

    Pochopenie rozsahu t\u00fdchto probl\u00e9mov si vy\u017eaduje h\u013eadanie mo\u017en\u00fdch rie\u0161en\u00ed. V nasleduj\u00facich \u010dastiach sa pozrieme na strat\u00e9gie na odstr\u00e1nenie pruhov na obrazovke telev\u00edzora Samsung.<\/p>\n\n\n\n

    <\/a>Pr\u00ed\u010diny \u010diar na telev\u00edznej obrazovke<\/strong><\/h2>\n\n\n\n

    \u010ciary na telev\u00edznej obrazovke sa m\u00f4\u017eu vyskytn\u00fa\u0165 v troch pr\u00edpadoch:<\/p>\n\n\n\n

      \n
    1. Nestabiln\u00fd sign\u00e1l je sign\u00e1l, v ktorom je naru\u0161en\u00e1 synchroniz\u00e1cia. V tomto pr\u00edpade bud\u00fa \u010diary pravidelne deformovan\u00e9 alebo sa objav\u00ed pl\u00e1vaj\u00faci obr\u00e1zok. To sa m\u00f4\u017ee sta\u0165 aj vtedy, ak je v bl\u00edzkosti telev\u00edzora siln\u00fd zdroj \u017eiarenia. Napr\u00edklad som pozoroval pl\u00e1vaj\u00face obr\u00e1zky kv\u00f4li bl\u00edzkosti WiFi routera.<\/li>\n\n\n\n
    2. Druh\u00fdm d\u00f4vodom je porucha displeja; v tomto pr\u00edpade sa pruhy objavia ihne\u010f po zapnut\u00ed telev\u00edzora v\u017edy na rovnakom mieste a d\u00f4vodom ich v\u00fdskytu je porucha displeja.<\/li>\n\n\n\n
    3. Tak\u00e9to pruhy sa m\u00f4\u017eu objavi\u0165 aj v d\u00f4sledku por\u00fach softv\u00e9ru, ale tento jav je zriedkav\u00fd.<\/li>\n<\/ol>\n\n\n\n

      Trochu podrobnej\u0161ie: <\/strong>LED displeje maj\u00fa bunky (pixely), ktor\u00e9 obsahuj\u00fa \u0161peci\u00e1lnu kvapalinu z tekut\u00fdch kry\u0161t\u00e1lov; ke\u010f na \u010dl\u00e1nok privediete \u0161pecifick\u00e9 nap\u00e4tie, kry\u0161t\u00e1ly sa usporiadaj\u00fa ur\u010dit\u00fdm sp\u00f4sobom, zmen\u00ed sa polariz\u00e1cia a svetlo z podsvietenia prech\u00e1dza cez kry\u0161t\u00e1l, tak\u017ee dostaneme obraz na obrazovku. Ak s\u00fa pruhy, znamen\u00e1 to, \u017ee niekde v matici displeja do\u0161lo k poruche v riadiacich obvodoch; pixely s\u00fa v\u017edy pod nap\u00e4t\u00edm, stali sa nekontrolovate\u013en\u00fdmi a svetlo nimi prech\u00e1dza. Tak\u00e1to porucha sa spravidla vyskytuje v d\u00f4sledku elektrickej poruchy; v tomto pr\u00edpade sa m\u00f4\u017eete pok\u00fasi\u0165 trochu napravi\u0165 situ\u00e1ciu a druhou mo\u017enos\u0165ou je fyzick\u00fd dopad; obrazovka je rozbit\u00e1 a v tomto pr\u00edpade nem\u00f4\u017eete ni\u010d robi\u0165.<\/p>\n\n\n\n

      <\/a>Oprava \u010diar na obrazovke telev\u00edzora Samsung<\/strong><\/h2>\n\n\n\n

      Ni\u017e\u0161ie uveden\u00e1 met\u00f3da pom\u00f4\u017ee odstr\u00e1ni\u0165 \u010diary, ale neoprav\u00ed v\u00e1\u0161 displej. Oprava spo\u010d\u00edva v odpojen\u00ed, odstr\u00e1nen\u00ed nap\u00e4tia z chybn\u00fdch pixelov. Ak to urob\u00edte, bud\u00fa v\u017edy vypnut\u00e9. Na obrazovke bude neakt\u00edvny p\u00e1s pixelov, ale chybn\u00e9 pixely si sotva v\u0161imnete, preto\u017ee \u010dierna nie je tak vizu\u00e1lne v\u00fdrazn\u00e1. Je to nepochybne polovi\u010dn\u00e9 opatrenie, ale st\u00e1le v\u00e1m to umo\u017en\u00ed chv\u00ed\u013eu pou\u017e\u00edva\u0165 v\u00e1\u0161 telev\u00edzor.

        \n
      1. Rozoberte telev\u00edzor a n\u00e1jdite miesto, kde sa p\u00e1ska dr\u00f4tov z matrice obrazovky prip\u00e1ja k doske displeja. Ako m\u00f4\u017eete vidie\u0165 na obr\u00e1zku, tento konektor je zvy\u010dajne vpravo dole.<\/li>\n<\/ol>\n\n\n\n

Vyberte si maliarsku p\u00e1sku, ktor\u00e1 je zn\u00e1ma svojimi miernymi lepiacimi vlastnos\u0165ami, jednoduch\u00fdm odstr\u00e1nen\u00edm a tenkou. Neodpor\u00fa\u010dam pou\u017e\u00edva\u0165 baliacu p\u00e1sku. Dr\u017e\u00ed pevne a m\u00f4\u017ee zanecha\u0165 lepidlo na kontaktoch.

          \n
        1. Prelepte kontakty p\u00e1skou.<\/strong><\/li>\n\n\n\n
        2. Nain\u0161talujte k\u00e1blov\u00fd zv\u00e4zok do konektora.<\/strong><\/li>\n\n\n\n
        3. Zapni TV.<\/strong><\/li>\n\n\n\n
        4. Zdvihnite to.<\/strong><\/li>\n\n\n\n
        5. Starostlivo skontrolujte obrazovku.<\/strong><\/li>\n\n\n\n
        6. Pos\u00fa\u010fte kvalitu obrazu.<\/strong><\/li>\n\n\n\n
        7. Postup opakujte, k\u00fdm nebudete spokojn\u00ed s v\u00fdsledkom.<\/strong><\/li>\n<\/ol>\n\n\n\n

          Mal\u00e1 pom\u00f4cka: <\/strong>skupinu kol\u00edkov m\u00f4\u017eete lokalizova\u0165 tak, \u017ee naraz izolujete p\u00e4\u0165 kol\u00edkov a po lokaliz\u00e1cii postupne zn\u00ed\u017eite po\u010det nalepen\u00fdch kol\u00edkov.

          <\/a>Ko\u013eko stoj\u00ed oprava obrazovky telev\u00edzora Samsung?<\/strong><\/h2>\n\n\n\n

          Ak oprav\u00edte telev\u00edzor vy\u0161\u0161ie op\u00edsan\u00fdm sp\u00f4sobom, tak\u00e1to oprava, ak to urob\u00edte sami, bude bezplatn\u00e1, ale str\u00e1vite 2-3 hodiny. Hlavn\u00fdm probl\u00e9mom, ktor\u00e9mu budete \u010deli\u0165, je rozoberanie telev\u00edzora. V z\u00e1vislosti od modelu telev\u00edzora m\u00f4\u017ee by\u0165 demont\u00e1\u017e jednoduch\u00e1, existuj\u00fa v\u0161ak modely telev\u00edzorov, ktor\u00e9 m\u00f4\u017eu vy\u017eadova\u0165 ur\u010dit\u00fa zru\u010dnos\u0165. Napr\u00edklad telev\u00edzory s jedine\u010dn\u00fdmi dr\u017eiakmi krytu vy\u017eaduj\u00fa talent a zru\u010dnos\u0165 na demont\u00e1\u017e. Ak d\u00e1te telev\u00edzor na opravu odborn\u00edkovi, oprava bude st\u00e1\u0165 3 a\u017e 4 hodiny pr\u00e1ce a m\u00f4\u017ee sa pohybova\u0165 od nieko\u013ek\u00fdch dol\u00e1rov a\u017e po nieko\u013eko desiatok dol\u00e1rov za hodinu v z\u00e1vislosti od krajiny.<\/p>\n\n\n\n

          V\u00fdmena obrazovky je tie\u017e mo\u017enos\u0165ou, ale \u00faprimne povedan\u00e9, nepraktick\u00e1: cena displeja plus pr\u00e1ca bude rovnak\u00e1 alebo dokonca drah\u0161ia ako k\u00fapa nov\u00e9ho podobn\u00e9ho telev\u00edzora.<\/p>\n\n\n\n
