Poci\u0165ujete pr\u00e1zdnou obrazovku, p\u0159esto\u017ee je v\u00e1\u0161 po\u010d\u00edta\u010d v provozu? Prozkoumejte n\u00e1sleduj\u00edc\u00ed \u0159e\u0161en\u00ed, kter\u00e1 mohou pomoci vy\u0159e\u0161it probl\u00e9m.<\/p>\n

1. Vynucen\u00ed restartov\u00e1n\u00ed po\u010d\u00edta\u010de<\/strong><\/h3>\n

Jedn\u00edm z nejjednodu\u0161\u0161\u00edch \u0159e\u0161en\u00ed je prov\u00e9st vynucen\u00fd restart. To m\u016f\u017ee vy\u0159e\u0161it do\u010dasn\u00e9 z\u00e1vady, kter\u00e9 mohou br\u00e1nit fungov\u00e1n\u00ed va\u0161eho displeje. Postupujte takto:<\/p>\n

    \n
  1. Stiskn\u011bte a podr\u017ete tla\u010d\u00edtko nap\u00e1jen\u00ed<\/strong> na po\u010d\u00edta\u010di.<\/li>\n
  2. Dr\u017ete jej asi 4-5 sekund, dokud se syst\u00e9m nevypne.<\/li>\n
  3. Op\u011btovn\u00fdm stisknut\u00edm tla\u010d\u00edtka Nap\u00e1jen\u00ed<\/strong> po\u010d\u00edta\u010d znovu zapn\u011bte a zkontrolujte v\u00fdstup displeje.<\/li>\n<\/ol>\n

    2. Zkontrolujte monitor a kabely<\/strong><\/h3>\n

    Ne\u017e se pono\u0159\u00edte hloub\u011bji do \u0159e\u0161en\u00ed probl\u00e9m\u016f, ujist\u011bte se, \u017ee v\u00e1\u0161 monitor funguje spr\u00e1vn\u011b a \u017ee jsou v\u0161echny propojovac\u00ed kabely neporu\u0161en\u00e9. Pod\u00edvejte se, zda na kabelech HDMI nebo monitoru nen\u00ed n\u011bjak\u00e9 viditeln\u00e9 po\u0161kozen\u00ed. Pokud zjist\u00edte n\u011bjak\u00e9 probl\u00e9my, v\u00fdm\u011bna kabelu m\u016f\u017ee v\u00e1\u0161 probl\u00e9m vy\u0159e\u0161it.<\/p>\n

    Krom\u011b toho otestujte monitor s jin\u00fdm po\u010d\u00edta\u010dem. Pokud to tam funguje dob\u0159e, probl\u00e9m spo\u010d\u00edv\u00e1 ve va\u0161em p\u016fvodn\u00edm syst\u00e9mu. A naopak, pokud nefunguje s jin\u00fdm po\u010d\u00edta\u010dem, v\u00e1\u0161 monitor m\u016f\u017ee vy\u017eadovat servis.<\/p>\n

    3. Odpojte v\u0161echna perifern\u00ed za\u0159\u00edzen\u00ed<\/strong><\/h3>\n

    K probl\u00e9m\u016fm se zobrazen\u00edm mohou p\u0159isp\u00edvat tak\u00e9 extern\u00ed perifern\u00ed za\u0159\u00edzen\u00ed. Chcete-li zkontrolovat konflikty, systematicky odpojujte ka\u017ed\u00e9 p\u0159\u00edslu\u0161enstv\u00ed p\u0159ipojen\u00e9 k po\u010d\u00edta\u010di. Pokud monitor po odpojen\u00ed p\u0159\u00edslu\u0161enstv\u00ed za\u010dne znovu fungovat, pravd\u011bpodobn\u011b jste na\u0161li vin\u00edka. Pokud probl\u00e9m p\u0159etrv\u00e1v\u00e1, pokra\u010dujte dal\u0161\u00edm krokem.<\/p>\n

    4. Znovu usa\u010fte pam\u011b\u0165 RAM<\/strong><\/h3>\n

    Pokud jste ned\u00e1vno upgradovali nebo nainstalovali novou pam\u011b\u0165 RAM, nespr\u00e1vn\u00e9 usazen\u00ed m\u016f\u017ee zp\u016fsobit probl\u00e9my se zobrazen\u00edm. Zde je n\u00e1vod, jak to \u0159e\u0161it:<\/p>\n

      \n
    1. Stisknut\u00edm a podr\u017een\u00edm tla\u010d\u00edtka Nap\u00e1jen\u00ed<\/strong> vypn\u011bte po\u010d\u00edta\u010d.<\/li>\n
    2. Odpojte po\u010d\u00edta\u010d od zdroje nap\u00e1jen\u00ed.<\/li>\n
    3. Otev\u0159ete sk\u0159\u00ed\u0148 po\u010d\u00edta\u010de.<\/li>\n
    4. Vyjm\u011bte RAM sticky, o\u010dist\u011bte moduly i sloty pomoc\u00ed had\u0159\u00edku z mikrovl\u00e1kna a znovu je pevn\u011b p\u0159ipojte.<\/li>\n
    5. Zav\u0159ete sk\u0159\u00ed\u0148, znovu p\u0159ipojte nap\u00e1jen\u00ed a zapn\u011bte po\u010d\u00edta\u010d, abyste zjistili, zda se displej vr\u00e1til.<\/li>\n<\/ol>\n

      5. Resetujte BIOS na v\u00fdchoz\u00ed nastaven\u00ed<\/strong><\/h3>\n

I kdy\u017e je obt\u00ed\u017en\u00e9 resetovat BIOS bez displeje, m\u016f\u017eete tak u\u010dinit vyjmut\u00edm a op\u011btovn\u00fdm vlo\u017een\u00edm baterie CMOS na z\u00e1kladn\u00ed desku. Zde je postup:<\/p>\n

        \n
      1. Vypn\u011bte po\u010d\u00edta\u010d a odpojte v\u0161echna perifern\u00ed za\u0159\u00edzen\u00ed spolu s nap\u00e1jec\u00edm kabelem.<\/li>\n
      2. Opatrn\u011b otev\u0159ete sk\u0159\u00ed\u0148 po\u010d\u00edta\u010de a najd\u011bte baterii CMOS na z\u00e1kladn\u00ed desce.<\/li>\n
      3. Vyjm\u011bte baterii pomoc\u00ed nehtu nebo mal\u00e9ho n\u00e1stroje a pot\u00e9 n\u011bkolik minut po\u010dkejte, ne\u017e ji znovu vlo\u017e\u00edte.<\/li>\n
      4. Zav\u0159ete sk\u0159\u00ed\u0148, znovu p\u0159ipojte v\u0161echny kabely a zapn\u011bte syst\u00e9m.<\/li>\n<\/ol>\n
