Buna ziua , acest televizor la pornire are backlite 2 secunde dupa care se sting neoanele si se aude doar sunetul , in perioada aceasta imaginea este mai intunecata in centrul vertical al imaginii ca si cum CCFL-urile ar fi dispuse vertical si unul din ele pe acea portiune ar fi defecta ( ?? ) , dar deoarece nu cred ca e asa ci sint orizontale inseamna ca e defect modulul invertor ( INVFT320A ) ? acesta se alimenteaza cu 24,3 volti masurati in acele 2 secunde de vizibilitate a imaginii , elco-urile pe aceasta bara le-am schimbat . Multumesc

Controlerul la acest invertor este BD9882F , am gasit ca pinul 12 - COMP ar fi under si over voltage detect , pinul acesta se ocupa cu intrarea in protectie ? MultumescL.E. : se poate inchide , am gasit printre modulele din dezmembrari un invertor identic cu care functioneaza ok , multumesc
