    Desoldering Station Switching Power Supply Problem Cold

    When I bought this desoldering station I recap both board and work good except when the temperature is less than 40* F them the power supply will switch ON for 2 seconds then would shut down for 2 seconds and might do this four or five time before it will stay ON

    I had used some FC FR KY KME what would fit on these two boards

    when it 60*F or warmer it works jum st fine with no problem

    Can anyone tell me why this power supply would be doing this

    The first time I turn this unit ON out of the box before I recap it ,it did the same thing power up two or three time before it would stay on

    Re: Desoldering Station Switching Power Supply Problem Cold

    Reminds me of my Soyo SY-K7VTA-B motherboard with Deer 250 W PSU!

    One morning, (likely 2002) when it was less than 40 F, right after hitting the power button, I got that bitchy lady's voice message "The VGA card might not be installed properly".

    But it booted after pressing the reset button on the case. (or after power cycling)

      Desoldering gun station modified to use a 18 volt @ 20 amp switching power supply
      by sam_sam_sam
      I have wanting to do this project for quite sometime now and I finally found a switching power supply that will work on this desoldering gun station ZD-915 that the original switching power supply took a shit and just was not worth trying to fix it because this switching power is not quite big enough to handle the heater element and the vacuum pump

      One note when I tested the switching power supply and the voltage control board I noticed that this desoldering gun heat up much faster than the original switching power supply which I was really surprised by to the point that I might buy...

      Modification to a ZD-987 desoldering/soldering station using a external switching power supply
      by sam_sam_sam
      I have been working on this concept for quite some time now with limited success but recently I found a switching power supply that is setup for the voltage that this soldering station needs to operate at however it also needs part of the secondary circuit from the original switching power because you need several voltage rails

      I once tried to get a ZD-915 desoldering station to work on a 18 volt battery power supply but unfortunately things did not go well but I did find a work around but I might try this idea again but going at a little differently more about this another time...

      Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?
      by Tynan Dill
      I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.

      Upon bringing it home and plugging it up, it showed a standby light.

      I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.

      The screen seems to blackout and stay black, but with a flashlight I can see the display.

      With my Playstation 4 connected via HDMI, and running a game I can hear sound.

      DVR camera recorder switching power supply capacitor failure really
      by sam_sam_sam
      These cheap non brand capacitors at it again

      Last night we had a power outage [ long drawn out trying three to come back up before going out completely ] and when I went to turn the DVR camera recorder back today no go 3 bad capacitors ( one capacitor no ESR reading on DVR board the other 3 capacitor on the power supply board over 40 ohm this is not a misprint ) on the external switching power supply and one capacitor on the DVR camera recorder board where the power supply that goes to the hard drive disk is

      Well at least I have the cameras back on line I to try the...

      Panasonic switching power supply daughter board has two 27uf @ 50 volt capacitors which I do not keep in stock
      by sam_sam_sam
      I did not have any 27uf @ 50 volt capacitors but one nice thing is that it has enough room for two capacitors in parallel a 22uf and a 4.7uf @ 50 volts 22 plus 4.7 equals 26.7uf which so very close to 27uf I will show some pictures of it sometime tomorrow

      This is one of the shit est boards I seen in a very long time and it was the daughter board the traces just lifting off the board I had to use the capacitor leads to repair the the traces and the main board is not any better because I had to repair several traces for the daughter board to the main board

      After all of...
