Yes!!! Both of you are right!
It finally works. Pheewww.......
I've replaced Q342 or Q341 at start with transistors that doesn't match ( NPN instead of PNP ) ( it doesn't work without Q342 & Q341 too at the beginng of the repair, so i don't have seen that) )so reset was always activated i think
I've removed them for now and it works
Thanks to both of you for your diagnostics, very appreciated
There was multi problems on this board but now it works flawlessly
