Hi,
I did clean the whole pcb, first used air then contact spray, that was on sunday evening.
Result was negative too.

On the right side of the pcb, in the area where the BMU board is,there are
some MB8128 chips, according to google those are Ram chips.
Am I right ?
I'm going to re-solder those today.
Will report later tonight.

Original replacement board will cost a fortune,and it would be the second in 5 years,
so trying the bad connection road for the moment.
But I think without a circuit drawing finding a bad chip will be too tricky for me, although I am not a complete
dummy in electronics.
Anyone out there having a board for a reasonable price,can even be broken in case we find the error and it
is a proprietary fanuc chip, that also would cost a fortune.
Almost everything costs a fortune in this area,I know.


Thanks

I have schematic diagram but it is in hard copy, tell me what area you want to know. PM me your email
