Hi guys we have a Rca atc113ba1 chassis which will not come on looks like it is shuting down as the isolation supply is pulsing the current on and off..I suspect the flyback transformer. Anyone have the part number of the flyback in this chassis and am I correct in a defective fly..Are there other parts in this chassis to cause this problem..Output Transistor checks ok as well as all diodes and electrolytics in the circuits.
