Din sursa avem o tensiune de start care ajunge in driver . Dupa 2 secunde de functionare tensiunea din colector prefinal scade nefiind comandat din TDA9351PS/N2/3I1308 . Sursa tine aprins bec de 75W cand intrerup colector TZ final linie . Am schimbat si cadrele si trafolinie . Poate sa mai fie def si altceva in afara de jungla ? Multumesc anticipat pentru ajutor .

In cele 2 secunde de functionare se aude un tiuit in trafolinie , cred ca frecventa este alta . In baza prefinal linie frecventa nu se mentine , de aceea cred ca se blocheaza driverul pe care l-am si inlocuit . Ce sa-i mai fac ? Mentionez ca nu am aparat de masura al frecventei , nici osciloscop . Repar tv de ceva ani , am o minima experienta dar defectul acesta ma depaseste .

Modelul este CZ-21M063N .

Finalul linie este D2499 .

Am schimbat si cuartul de langa procesor .
