suggestions.- you remove the flyback and the hot, place a 75w bulb or a 680 ohms 20w resistor from the ground b +, with this you can check the conditions of the source.- 2.- place your frequency meter at the base of the hot le you give on and check the frequency 15750 cycles. With this you discard the source and the oscillation, just as it is without the flyback, take advantage to remove the vertical ci and check all the filters with an esr meter, and the resistances those that are in the abl have to be exact.- comments. regards.

To start, tell us if you have already checked any TV before and if you are trained for it.- On the other hand, your TV may have open welds on the card. Rate and comment! Regards!
