    A rare circus board sighting! Another quality D-Lab repair.

    Where I work whenever a repair comes in with a blown diode bridge, it usually takes out a pair of diodes, which in this case was the other iffy diode. We always replace all 4 diodes to prevent future failures from occurring in case the other diodes were stressed.

    What an incredible demonstration of a prolific ability with electronics well beyond the typical audio/video sort. This was a good departure from the norm. Terry, I appreciate these wide-ranging areas of expertise. I can't wait for the next session.

    Got the same mag drill in my shop. If it ever goes down for the count, I'll know where to look. You are the man!

    For years in the consumer industry I saw a massive amount of 'lytics with bad electrolyte. They leaked all over and it smelled like rotting fish. "Fish caps" we called them. A very huge cash cow for me, especially with t he Mitsushibi CRT TV sets. typically they needed 52 caps replaced!

    a great trouble shooting video for these drill presses or anything with an electronic control board.

    I never was a fan of solder wick. Easy to overheat the board and lift circuit traces. A good solder sucker, either manual or with a vacuum pump, does a easier, quicker job without hurting the board.

    Haven't missed a D-lab video in years. Thanks for all the posts! I used to work with you in AZO (any guesses?). One question: Do you try to re-apply conformal coating to a re-worked industrial circuit board?

    • @d-labelectronics
      @d-labelectronics  Рік тому +1

      I used conformal coating in the USAF. We had it in spray and brush on. Have not used it since. Did we work at Parker (Pat Gipper)?

      @MrGip199 Рік тому +1

      @@d-labelectronics Yes, you can spray or brush acrylic coatings (type AR), which is basically the same as nail polish, to protect from moisture intrusion. Mostly for sensitive circuits involving Op Amps. Not as much concern in power supply unless it is soaked. Parker is correct! Urethane (type UR) is even better, but is more difficult during repair.

    I just received a 4203 for repair. Owner states it turns on then immediately turns off. I've not touched it yet. Anyone have a formal schematic for the board or ideas on what to check?
