TKS FOR YOUR REPLY,
I did it maytimes but in vain,

the chip was programmed before a month a go run well on both breadboard and pcb
but the chip programmed (the same program) later has not run at all on both breadboard and pcb
now program is reduce to a signle led to be easy to control but not run at all.
this happened some years ago but now i forgot how to fix it (nothing to fix as i remember) but now i have to find out the root of a problem
