          right ordered the lm2475 ic as it reads 2.5 volts and not 5 volt so iam assuming this may be the problem ?

            I HAD gave the link above and THERE I HAD WROTE - check ouput voltage NOT ON OUTPUT OF LM2475, check the voltage AFTER CHOKE.
            open datasheet and LOOK THERE TYPICAL USING DIAGRAMS.
