Mai degraba ar ajuta sa mentionezi unde este montata, eventual o poza cu ea in montajul respectiv.S-ar putea deduce astfel ce regim de functionare ar avea acolo.

In zona este sursa de 5V Stand-by. Cred ca poti pune o dioda rapida ca BY 299 sau asemanatoare.

:nas: ....dupa cum este figurata apare a fi o dubla dioda zenner de protectie ceva gen "Single Chip Dual Cathode to cathode zener protections".... sau "Zener Transient Voltage Suppressors"Dar ce problema aveti ...apare intrerupat in ambele sensuri la masurare?

Tv-ul este un philips de 47" PHILIPS+Q529.1E+LA. Se aprinde dar am ecranul gri, numai back light.Am masurat iesirile din sursa unele sunt bune altele cu 1v peste.

Scuze, am vazut dioda din pozitia 106, nu 106A.Asa este, nu e dioda redresoare rapida acolo, e supresoare cum a scris dl. Angelescu.
