thank you Joe for answer.
I get both parts from germany via Radel s.a(Greece)
I trust my supplier radel.
I work with them for more than 10 years.
And i think that they trust their supplier too.

I tried the "3 reset pulses" method.
And again , the old chips went to isp,
but the new chips no action.
Same thing with "clock-in".
On monday i'll try to find a parallel programmer
and i ask for new chips.
