lcd samsung le26r74bd (r) schema invertor

Recommended Posts

Verifica lampile pe un invertor extern, fiecare in parte. Se pot gasi invertoare recuperate de pe laptop-uri sau chiar de pe forum.Daca o singura lampa e defecta, invertorul trece in stand-by.Poti sa le inspectezi si vizual, cele uzate prezinta innegrire accentuata la capete, am gasit chiar izolatia de cauciuc carbonizata intr-un caz.Trebuie masurati tranzistorii invertorului si refacute lipiturile suspecte prin zona trafo invertor si verificati/schimbati condensatorii electrolitici (invertorul are filtrajul propriu pe placa)
