Ok, previously I have got the first two digits to work fine.
But, here is the last one: I thought it would be okay but this one is showing '8' meaning high on all outputs of SR all the time.
I have put on the 220nF fairly close to the third SR.
Also, when I try to check the output voltages for 2nd shift register, it changes its value as DMM probe is touched. Is it Electro-static discharge or something?
This is really weird. Need your suggestions!!
Thanks folks!
