Subject: Re: [PolySix] some defects after battery leak

Hi all,

I just fixed it. Thanks all for looking into my problem. It was a problem with a dataline to the multiplexers. So Simon and Don B( reply from May 15 )  were right ! It was pin 10 of IC 18 that was corroded. By that, P21 ( pin 22 )  on processor IC22 was not connected to Pin 10 of IC18.
I tried to repair it in 2006 and 2010 without success. Thanks to you guys it is solved !!
Thanks again and greetings from Belgium, Europe.

Johan

I suspect some address lines not connected to all the 4051 ic's
