Hi Brian, i HAVE A FAULTY dvr WITH A SMALL PILE OF BROWN GUNK AT THE END OF THE LITTLE CLOCK CRYSTAL 32.768 kHZ IS THAT COMING OUT OF THE CRYSTAL? is THERE SOME "STUFF" IN THE CAN WHICH COULD LEAK OUT? oTHERWISE IT MUST BE FROM A SMD CAPACITOR NEARBY. WHAT DO YOU THINK? AND HOW CAN I NON DESTRUCTIVELY TEST THAT CRYSTAL? ( The website field has some microcapture microscope images in a zip file )]]></description> <content:encoded><![CDATA[<p>In reply to <a href="https://www.circuitcrush.com/crystal-oscillator-tutorial/#comment-44">Brian</a>.</p> <p>Hi Brian,<br /> i HAVE A FAULTY dvr WITH A SMALL PILE OF BROWN GUNK AT THE END OF THE LITTLE CLOCK CRYSTAL 32.768 kHZ<br /> IS THAT COMING OUT OF THE CRYSTAL? is THERE SOME “STUFF” IN THE CAN WHICH COULD LEAK OUT? oTHERWISE IT MUST BE FROM A SMD CAPACITOR NEARBY.
