Sanatate !! Se  gaseste o schema pentru acest tv?

Defectul este urmatorul: Ledul de stand-by este aprins .. la plecare in power-on , toate tensiunile secundare scad la 0v ... Am scos tranzistorul final linii si am pus un bec ... Pe bec sursa pleaca din stand-by si tensiunile  nu mai scad la 0v , iar B+ este de 116v...

Am schimbat electroloitici in proportie de 90% , cei din sursa si tensiuni recuperate sunt inlocuiti !!

Dupa plecare din stand-by am observat ca apar pentru  cateva fractiuni de secunda si tensiuniile recuperate ... dar nu stiu daca sunt normale , deoarece nu am schema ..
