Ajutor pentru depanat un LG!

Recommended Posts

Am si eu nevoie de schema unui TV LG CF-20E20X care face urmatoarea figura: Dupa 10 minute de mers normal intra in Stand by.

Mentionez ca am gsit ca trz. final de linii (2SC5250) se incalzeste destul de tare. Daca-l pornesc din nou porneste iar normal si mai merge cateva minute dupa care iar se opreste. Am inlocuit tranzistorul cu un BU2508 si e tot asa incins. Daca i-l racesc cu un ventilator merge fara probleme si nu crapa nimic!

Am cautat traf de linii de schimb (HR8163) dar nu l-am gasit ca sa-l inlocuiesc.

Aveti vreo idee sau o schema va rog?

Multumiri anticipate.
