The only thing that will make a difference is you posting a schematic.

well if i had a schematic i would surely post it instead of circuit

board
pictures.

i was hoping some one might notice the chips used and there

configuration
and maybe have an idea about how and what to look for.

thanks for help ,

you could make a list of the Ics on the board and download all the
datasheets for them. That should help you.

Hey Don,
I realize i am not even an electronic hobbyist more like a "dangerous
adventurere" at best when it comes to repairing electronics (i have
succesfully stripped 10 guage wire and i can distinguish resistor from
diodes most of the time)

but, how would looking up all the IC datasheets help ?

would it not be more efficient to concentrate only on the ICs directly
connected to the suspect components ?

thanks for your time,
rob
