Sziasztok!Ha van valakinek ilyen magnója kérem jelezze,megvenném!Működőképes alaplap kellene a többi fődarab nem lényeg,a végfok ic sem.Köszi!
A STDBY-LED a bekapcsolás kb. 3 mp után kialszik.A STDBY-LED-R bekapcsolás után a 0 V feszültség ugyan annyi idő alatt 3,3 V ra ugrik, akkor a Q623 RT1P441C-TP-1 led drive nem tud működni. Az EVER+3.3V és az EVER 4V mindig mérhető. A készülék szervíz kézikönyve elérhető a Fórum oldalain.
I found that VC1 0n IC11 is missing. After checking I found C25(330u 35V) s/c i.e. defect. The problem solved.
Sziasztok. Van ez a Technics SU600 ami furcsa dolgot produkal: bekapcsolas utan 3-4mp-re kigyul a "safety" led, ennek ellenere a SVI3102 kimeneti labain nem merheto feszultseg. A 7. labon -4,2v merheto, ami megfelel a "safety" allapotnak. Namostmar ahany hibas STK/SVI peldannyal dolgom volt, mindnek a kimenetein volt feszultseg. Ezt a peldanyt nem tudom hova sorolni. Ha meghibasodott a vedelmi resze es tiltja a csatornakat, ugyanugy kuka, mintha valamelyik csatorna szallt volna el. Errol kernem a velemenyeteket; esetleg talalkozott valaki ilyen helyzettel?
Sziasztok!
Tudna valaki valamit ajánlani? Nyákterv sem lenne rossz. Be kéne már végre fejeznem...
Köszönöm!
