Acest sasiu a intrat in posesia mea....posibil de la posesor, nu de la reparator...am schimbat trafo linii, scurt intre spire pe bobina de BV. Tv functioneaza normal.


PS:A fost umblat in el ca in codru, din cauza unui CI de la BV - nu mai folositi pasta decapanta de pe timpuri - oxideaza in timp si are si conductie
