  476. <p>00:00 &#8211; JBL Partybox 310 Speaker fault symptoms and initial failure speculation<br />
  477. 02:57 &#8211; Teardown<br />
  478. 06:23 &#8211; Is it a firmware lockup issue?<br />
  479. 07:17 &#8211; Checking the power switch<br />
  480. 09:13 &#8211; Main PCB&#8217;s<br />
  481. 10:52 &#8211; Hello IT, have you tried turning it off and on again<br />
  482. 11:46 &#8211; PCB microscope inspection<br />
  483. 13:39 &#8211; Bench testing and, thou shalt test voltages<br />
  484. 16:31 &#8211; Looking at the keypad PCB again<br />
  485. 17:41 &#8211; Replicate the fault using an external PSU<br />
  486. 22:55 &#8211; Schematic, we have Schematic!<br />
  487. 24:14 &#8211; The power flow block diagram<br />
  488. 28:44 &#8211; The penny drops<br />
  489. 29:45 &#8211; Design TIP<br />
  490. 32:04 &#8211; Without the schematic I&#8217;d be chasing a red herring down a rabbit hole<br />
  491. 33:10 &#8211; Manual Bypass time to get it working!<br />
  492. 34:50 &#8211; I called it at the start, but assumed incorrectly<br />
  493. 36:33 &#8211; OK, let&#8217;s trace WHERE this fault actually is<br />
  494. 37:41 &#8211; No, it&#8217;s can&#8217;t be, surely not&#8230;<br />
  495. 39:52 &#8211; But WHAT caused it?<br />
  496. 42:05 &#8211; The repair<br />
  497. 44:20 &#8211; Assembly back together and testing</p>
