Arrived with vertical closed | Replaces q301 tda9302h and its voltages do not match the pin 1 and 7 scheme, it has to give 3volts and pin 2 26.8volts and 6 27.3volts... this last one only gave 8.9volts | Check r320, c308, (d301(replace without measuring)) resolved normal vertical deflection. If it doesn't work, check q830 5v regulator that powers pin 7 of q301, see r311 and r310. If that doesn't work, see c301 may be open near the computer. | WagnerAlves |
