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 | |
