    SM Electronics Supervision 2100 dvd player

    I have a SM Electronics Supervision 2100 in repair.

    i opened the dvd player and is see lots of Taicon(wtf!) capacitors inside.

    one of the capacitors is a big cap of 450V!!

    how to discharge this?

    No sparks, thanks.

          Most switchers bleed the line cap when the plug is pulled the cap allows them to run for a few seconds after power is disconnected. Others have a bleeder resistor across the cap that does the same thing. Most line caps are completely discharged in a matter of seconds after disconnecting through one of those two routes.

          If you're worried about the cap measure it with a DMM if it's 0 volts it's fine if it's not put a 5W wirewound resistor across the leads to discharge it.
          Elements of the past and the future combining to make something not quite as good as either.

              Repairing the Hitachi DA-6000 CD player
              by nervous_capybara
              Hello everyone !

              I recently conducted maintenance on a Hitachi DA-6000 CD player for my grandparents : it had two distinct issues.
              Feel free to share your experience if you ran into other issues.

              DISCLAIMER : BE VERY CAREFULL WHEN OPERATING ON THIS SYSTEM : THE HIGH VOLTAGE IS VERY CLOSE TO THE VARIOUS TESTING POINTS, PROCEED WITH CAUTION

              Artist seeking to tinker with electronics safely
              by Hypersapien
              Howdy folks! I'm an artist in the video game industry, and my job entails making a lot of mechanical and sci fi assets. I thought it might be a good practice to start disassembling some electronics to be more familiar with how real electronics are manufactured and assembled, which is how i found my way to these forums.

              When I started researching what tools I might need, I quickly encountered the warning "Some devices can maintain a potentially lethal charge in their capacitors, even up to years after last being powered on", which was enough of a scary thought for me to...
