Re: QuadraFuzz Troubleshooting
It's OK posting here, or, email direct to email@example.com
As long as you were careful with the CMOS IC it is likely not the trouble. Usually it is just an accidental short-circuit to it or reaching down to touch it and a spark from static discharge passing through it that would take it out.
There are some extras including trouble-shooting tips and suggestions over in this section of PAiA Talk: viewforum.php?f=23
But also, check to be sure the four ICs 1-4 are in the proper spots with respect to 4016 and 4136, and, to polarity. Sometimes die flashing can be confused as indicator for pin 1, but in almost all instances, the markings across the part will be lengthwise between the rows of pins and when the board is positioned for reading left to right, pin 1 will be the leftmost on the lower row of pins. For the two Voltage Regulators, go back and check again to be sure the 7805 and 7905 parts are not in each others places.
If an IC is out of place or backwards, use a bulb or springloaded pump to vacuum melted solder from each pin so the part can be pryed off and re-installed or replaced.
Here's to success!
