Backlight Inverters: master/slave; should both be replaced?
Philips 47PFL7432D/37 suddenly started to flicker and go dark on one side only. Symptoms point to backlight inverter. TV has master and slave inverters; by location seem to be associated with sides of screen. As a rule (general or specific), should both inverter boards be replaced if it seems that only one is failing?
Is this a good question?
