I try to check all the board n :
I check pin (RESET') 6 in J8 and i found that is always low
thats mean that the chip is always reset?
If answer is true, i think that is something wrong.
I look a Q1 colector, and that transistor has allways a 0, i think
that`s output must be 1 if do no has a imput signal..
i think that is the problem but i do not know to do...
