    Bench Power Supply

    Time I bought some more equipment I think and now considering a Variable Bench PSU.

    How valuable to you guys is having one?

    Any suggestions for best range of variation when working with TV's and Computer Hardware?

    Cheers

          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.

          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...

          Hi, Can we use SMPS Bench Power Supply for Laptop troubleshooting?
          by shamsudeen
          Hi all, I just need to know that, can i use SMPS type power supply to test and short circuit detection on a laptop motherboard?
          I saw 95% of repair guys are using only Linear bench power supply. linear bench power supply is pricy, thats why i planned to get one SMPS supply.

          i know that in linear power supply the noise will be very low comparing to SMPS supply....

          LENOVO IDEAPAD 100 works only on bench power supply
          by rabsonnjala
          Hie I have a Lenovo laptop
          Lenovo Ideapad 100-14IBY AIVP1-AIVP2 LA-C771P rev 1.0
          it's working only on the bench power supply when I put the battery it doesn't power on. when I also use the original charger it doesn't power. the batter Is fully charged, I used another laptop to charge the battery. but when I use a bench power supply it works perfectly

          below are my readings

          with the original charger only
          JBATT1
          PIN1 0.22V
          PIN2 0.22V
          PIN3 0.45V
          PIN4 0.45V
          PIN5 O.43V
          PIN6 0V
          PIN7 GND
          PIN8...

          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...
