Hi
I know it's the polysix group but there's a lot of tech people around who
could possible give me some clues...
My Poly 61 at start up freezes with the initial message "PS 61" in the
display.
I replaced the internal battery, but the malfunction continues.
I replaced all the boards with one other damaged Poly 61, except the CPU
board.
I also replaced the 2 chips CPU IC - 8049 from other CPU board.
Can't replace the CPU board because the other one I have is corroded by a
leaking battery...
This take me to conclude for a damaged CPU board (KLM 509 - new production).
Am I wrong?
Does anybody have any suggestion?
Do you have one of those in stock (KLM 509)?
Let me know, please.
Thanks and best regards.
