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... thank you. |
