If you are good with small tools, you might be able to cure the problem without replacing the small quartz crystal on the processor board. The goal is to remove all the brown crap that was used to glue the crystal to the board, without breaking the fine leads. Your tools, small round toothpicks, some 99% isopropyl alcohol. the stuff will still be a little rubbery, try to roll it back away from the leads and circuit pads. get it all out of there so everything is nice and shiny clean. Unfortunately the crap will oxidize the leads away, making them prone to break, especially where they enter the glass seal. It also becomes electrically unstable, loading the oscillator circuit.
They now use a white paint to secure the crystal. -larry once eveything is clean, we use a little piece of foam double stick tape between the END of the crystal and circuit board (1/8" square). stay away from circuit traces. 7/10/05 3:23:40 PM, "Brad Allen" <[EMAIL PROTECTED]> wrote: >We have a system in a doctors office that has a clock that seems to act up a >lot.
