    • Appliantology Live Dojo, Saturday, 4/27/2024 @10 AM ET
      27 April 2024 02:00 PM Until 03:00 PM
      5  
      All Appliantology tech members are invited to join in this workshop on all things Appliantological. 
      We have a special session planned for this one. Instead of the usual Show 'n Tell on a technical topic, we're going to post tech sheets in the comments to this Calendar Event (scroll down to see what's posted so far) and ask specific questions that can only be answered by reading the tech sheet. If you at least try to answer the questions beforehand, you'll get a lot more out of it. The tech sheet and the questions are posted in the comments section below.
      Your mission, if you should choose to accept it, is to check out the questions for each one and try to answer them ahead of time. Then come to the Dojo to see how well you did! 
      Who: This workshop is only available to tech members at Appliantology.
      When: Saturday, April 27 @10:00 AM Eastern Time.
      Where: Online via Zoom
      How:

Where can I get informtion on how to fix printed circuit boards?  I am constantly throwing out expensive boards for what should be a simple repair. For example I had to replace a board in a microwave oven the other day because the surface lights would not turn off and on.  Thanks  Gregg

Well, for starters you'd need the schematic for the board so you can begin to troubleshoot it. These are closely-guarded secrets that the manufacturers won't release without prolonged waterboarding. Then you'd need to know how to troubleshoot electronic circuits-- this is actually the easy part compared to getting the schematic.

In the course of running this website, I've met a few electronics geeks who can take a circuit board and reverse engineer it to the schematic. But these guys had degrees in Electrical Engineering and some kind of top secret job with the NSA... that's all they'd tell, something about for my own safety, I dunno.
