Philips 21PT1542/58S - defecte

Recommended Posts

Salut!La un Philips 21PT1542/58S am gasit tranzistorul 7505 (BC548B) de pe alimentarea procesorului ars. Dupa inlocuire televizorul merge, dar BC-ul se incalzeste. Am masurat curentul prin tranzistor si este in jur de 90mA. Care ar fi curentul consumat de procesor? Nu-i cam mult 90mA??La cautarea programelor am dat de a doua problema: cauta numai pe UIF. Ar trebui un dump??

BD681 este darlington si de curent FOARTE mare pentru aceasta aplicatie. O solutie eleganta este cu BC337 care are aceeasi dispunere a terminalelor, dimensiuni identice si curent/putere disipata absolut suficienta.
