Nag o on naman kaso na off at wla standby. Try ko replace strw6753 den on, ngka standby pero d na oscilate. Npancn ko nka series na ang dlawang 18 ceramic smay crystal oscilator. Bnun0t ko at tnester my leak pla un 3piraso pero ok pa ang 1. Ibinalik ko na sa dati na dlawa lang hanap ng auz. Den try e power on ulit nag oscilate na pero na off. Pnalitan ko pa 0.47/50v capacitor samay vertical C312 taz nlagyan 220/16v sa C409 kc npancn ko na wla nputol cguro at naiwan paa na kalawang na. Resolder ko na 2l0y main board at c-board.
