Sziasztok!
A címben jelzett 22″-os, LED háttárvilágítással működő monitor azt a parajelenséget produkálja, hogy alkalmanként a jobb felső sarokból kiindulva, két részletben félig lekapcsolja a háttérvilágítást.
Tehát első lépésben a jobb felső sarokban elhalványul a háttérfény, majd pár másodpercre rá középtájon is ugyanígy tesz. A képernyő alsó szekcióján és a bal-felső oldalán továbbra is intenzív marad a háttérvilágítás.
Nem mindig jelentkezik a hiba, — akár napokig sem — ha viszont egyszer rájön a görcs, akkor sorban egymás után produkálja a dolgot.
Egy-egy ilyen jelenség után ha stby kapcsolóval lekapcsolom a monitort, akkor mindig jó képpel tér vissza, hogy kb. egy perc után ismét eljátssza a produkciót.
Nem igazán tudom hogy merre induljak el. A kijelzője egy hátulról alaposan leburkolt nagyon vékony egység, de nem igazán tudom, hogy egyből kijelző hibában érdemes-e gondolkodni, vagy inkább az elektronikában lesz a gebasz. KH-ra nem reagál, hiába püfölöm…:-)
Bármilyen tapasztalatot és konstruktív ötletet szívesen vennék.
Köszönöm!

Sziasztok!
Több gépen is kipróbáltam, és mindegyiknél azt írja ki, hogy NO SIGNAL, hiába van bedugva, ha kihúzom akkor is ez jelenik meg ( ekkor érthető ) Kikapcsolt állapotban is kiírja amikor összedugom, szerintem a kapcsoló feszt megkapja, csak a jeleket nem dolgozza fel? Azt néztem ki a panelból, hogy a kábel bekötése egyből a prociba megy be, lehet hogy ez szált el?
Sziasztok!
A nevem Paksy Tamás. Nem túl régen kapcsolódtam az oldalhoz, de már rengeteget segítettetek. E monitor került hozzám, miben van egy tranzisztor, ami zárlatos, de a bolti ára eléggé borsos. A típusa : 2SJ598 . Ez egy PMOSFET. Valami hejettesítőt tudtok-e?
Üdv. mindenkinek!
Sziasztok!
A címben említett full HD-s(1920×1080) felbontású monitor «elfelejtette» a full HD-t! Júniusban vettük, idáig gyönyörűen működött, most viszont ha a video kártyán beállítom az 1920×1080 felbontást, akkor a kép szélei nem látszanak. A Windows két oszlopban lévő ikonjaiból semmi, a Windows logónak meg a jobb fele lelóg a képről! Olyan mintha a monitor csak 1600x1060as felbontást tudna! A kép így persze életlen, elmosódott, egyszóval pocsék! Hiába nymogatom a menüt, manuálisan nem lehet a felbontást állítani. Auto gombot nyomogatva sem veszi fel a HD-s felbontást! Mi lehet a baj? Vagy vigyem vissza a boltba?(3 év garancia van rá!) Ha valakinek van valami ötlete kérem, segítsen!
Üdv: lizakl
