[Heath] ICs WANTED

[cemilton at aol.com]

GM Sandy,
 
Re-seating the IC's is definitely in order.  However, if that doesn't fix the problem may I suggest looking at the small electrolytics.  Several years ago I encountered the same situation you have described and my first thought was the IC's.  Changing them out didn't help.  So I dug further into the circuitry and found one of the small (IIRC 10ufd @ low voltage) caps defective.  Changing that one cap cured the problem.  It's been over 15 years ago so I can no longer point to the exact cap.  Hope this helps.

Hi! Well, it made me laugh! The timer clock in my SB-634 has lost it. Really! From start (get this), the SECONDS digit counts BACKWARDS from 9 to 0. The TENS digit counts up from 0 to 5, but does so every second. The HUNDREDS digit counts from 1 to 9, triggered correctly by the TENS digit. It's gone looney.


Now, I think that it might a GOOD idea to get my IC Lifter thingie and reseat poor old IC204, 203 and 202.
And, according to the Manual ICOD Section, I guess I should also reseat ICs 101 and 103 on the Display Board as well.


I'm trying to keep my sense of humour sharp about this one, HI. If anyone has any clever thoughts for me, fire away!


73,  Sandy AC1Y
