No high voltage and no sound at all.Just a relay click and then the led will
start blinking.
I have already tried the vretical IC TDA8172 and still the same.
I think that the problem may be the jungle ic.If I am not mistaken,if the
data
bus is shorted to ground or if its held high,the set will not start up.Do
you by
any chance have the pin out of the jungle ic (IC351).Thanks
