Good friend Chavez thanks for your response, but I tell you that when I send the ignition order the screen receives its high voltage that goes from the flyback but I do not have the voltages on the trc board (there is no voltage) as I know if there is no oscillation to check, an easy way since I don't have an oscilloscope
Placing a focus (70w / 100w) between + B and the + B input pin of the FBT. Previously cutting or dividing said track to place the focus on both points of the cut track
In normal operation to the ON command the spotlight will illuminate and remain on until a new shutdown order is made.
Thank you friend Javier for your valuable response, in fact there was no oscillation since the track (very fine) that goes to smd resistance marked with a 222 etaba abiarta between the c2444 she there was the fault ..
