vertical deflection output ic number not visible
the set used to go off now and then to standby mode when brought for repairs. restartable
then suddenly it failed and now i cant get it to standby mode itself
powersupply comes on 12v 125v 9 v are appearing at the smps out put
but i cant see the vcc for the other two ics
