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 |

TV works normally, after a few seconds it turns orange, with a lack of blue. | Please 503 | Replace without measurement: because the transistor measures normal. | |

Image aliasing with ripple and hissing out of frequency. | C311=47pf for 160v dry and c329=4.7pf for 250v dry, both with zero capacity. | They were replaced and the TV stayed, great....! | Armando de Olimpia Elettronica EvoluSom |

Low sound | After checking the capacitor c449 I changed it and it didn't solve the problem so I followed the circuit from the 12 volt line to the mute transistors via q625 which also went to point 24 of the kinescope board connector, to my surprise it was the q907 open smd and that same one When the transistor comes on, it gives a blue screen. | Ed G.M.O eletronica | |

RGB with problem, red did not appear | I checked the RGB transistors, they were all normal, I redid the solders and lubricated the connector, after that it worked perfectly | paulo trinca |
