Am si eu o problema cu combina aceasta.Dintr-o data s-a oprit si nu a mai vrut sa porneasca,am desfacut-o si si am vazut pe placa Q003 crapat in doua dar totusi am reusit sa citesc pe el LF si dupa c am gasit schema am vazut ca LF corespunde cu 2SC3052F dar nu am gasit pe nicaieri sa cumpar asa ceva.Stie careva de unde pot cumpara asa ceva sau un inlocuitor pentru el?

2sc3052 este pe releu , tensiune 12v - in concluzie BD139 cred ca esteprea bun in aceasta situatie . Ambele sunt prezentate in attach .[attachment=0]datasheet bd139.rar[/attachment][attachment=1]datasheet 2sc3052.rar[/attachment]

Am pus bd139 in loc la 2sc3052 dar tot mi vrea sa functioneze ,in schimb cand apas butonul power se aude cu porneste si imediat se opreste releul si la fel face si displayul.Daca desprind legatura de la tranzistor la releu porneste displeyul ,merge meniul dar nu executa nici o comanda, ca nu a pornit releul.Ce altceva as putea sa i fac?
