SMPS regulation problem

Hi ,
I have designed 12v 3.5a smps using TOP245Y. I am using it in led display panel & it updates on every second.
My problem is when i use smps with led (seven segment)display, when display goes update, some segment will not lit or some will unnecessary lit.
I got new readymade smsp from market & that is working fine.
In my smsp no voltage drop. Can some one guide me what is the problem ?

sorry what is your set-up?.........can you take the 7seg out of the equation, then simply load your SMPS with a dummy load resistor of 12/3.5 ohms and tell what happens then?
