    Don't make them like they used to

    I know it's not a troubleshooting question but I didn't know where else to put this, so anyway...

    I'm recapping two screens right now and thought I would open my test/bench screen. It's been around for years and I thought it might be worth a look. So what do I find? Polys. That is why it has lasted so long.
    I got a kick out of finding those and a DVI connector on such an old screen. It's an HP f50.

    ps - It does 75hz refresh rate

    Looks like it uses an external PSU, that's the real reason it has lasted longer.

      Sir you are correct, but why would this make it last longer? It does remove the heat sources from the other components, but this also places the heat sources in a small unventilated box.



      I thought that diode in the picture was broken when I saw it. The break does look suspiciously clean and doesn't go through any of the print; is it a little ferret bead?

        Yes that's a ferrite (not ferret) bead.

          But ferret is funnier!

          But that small unventilated box is using excellent components. I see Panasonic(3) and Rubycon(1) capacitors. Plus generous heatsinks for the silicon.
