Monitor LG flatron

Recommended Posts

Monitor LG Flatron 17".Il bag in priza, il pornesc, se aprinde o secunda imaginea si dispare. Ledul power ramane verde si dupa ce se stinge ecranul.Daca e invertorul sau lampile defecte, mai ramane aprins ledul verde?

...si lampi dar si trafo din invertor,in situatia in care tensiunile sant ok,deci nu e vorba de electrolitici devalorizati!! Lampile de regula au defecte de contact la cuple si de aici ...problema!!

Inca ceva, ce nu stiam mai inainte.Dupa ce se aprinde si se stinge ecranul, singur mai repeta chestia asta de cateva ori dupa care merge.Sa inteleg ca in sursa e defectul, si anume conzi devalorizati?Sau tot se poate sa fie lampile sau invertorul?Ati mai intalnit acest tip de defect?

In ultimul timp am cam gasit trafuri duse in lguri.Masoara sa vezi,plus ai putea desfiinta protectia la invertor sa vezi ce face.

"Dupa ce se aprinde si se stinge ecranul, singur mai repeta chestia asta de cateva ori dupa care merge." - nu are cum sa fie trafo - invertor picat in atare conditii .

Acolo e pana de contact.Preventiv , schimba si filtrajele.

Condensatoarele electrolitice de pe bara de alimentare a invertorului.Dar dupa cate se vede, noi l-am reparat inainte ca el sa il desfaca ... :rade:
