    Faulty DVM

    One of my DVMs has gone faulty .
    I know why this has happened I was repairing some SMPUs ,they do have some high voltages on the 130volts and 425 volts .It has a range of 1000 volts this is why I was using this DVM .
    The high voltage has dammaged something ,it has gone noisey ( 2/3 didgits) but still seems to read .Exept it will not read diodes anymore
    If anyone could advise me about any thing I could replace .
    It has got a dual opamp on the board

    thank

    Can't help without a make and model number. Clear focused pictures on the sides would help too.

    If you are new to this forum, we can help a lot more if you please post clear focused pictures (max resolution 2000x2000 and 2MB) of your boards using the manage attachments button so they are hosted here. Information and picture clarity compositions should look like this post.

    We respectfully ask that you make some time and effort to read some of the guides available for basic troubleshooting. After you have read through them, then ask clarification questions or report your findings.

    Please do not post inline and offsite as they slow down the loading of pages.

      PS5 digital / No Power / No Beep / Good power supply
      by MisterAIL
      Hi everyone,

      Brought a non functionnal PS5. Apparently only a bad PSU...
      No beep, nothing.

      After some tests i found this :
      - PSU is fine (12 volts stable)
      - 12 volts line is shorted
      - DA9065 was fried, F7003 also => Replaced both of them, short is gone on 12 volts line, no dead short anywhere else.
      - By the way, nothing change. No signal, no power, no beep.

      Mesuring all rails with my workbench psu (12 volts input)
      - 0.00 amp drawing
      - 12 volts, 5 volts, 2 volts, 1,15 volts are presents (suppose new DA9065 do is...

      Dead Dell Latitude 5420 not receiving 20 volts from USB-C charger
      by BTubbs200
      Hello,

      Dell Latitude 5420 P137G
      Board: LA-K491P REV A01

      I have received this laptop which was described as "does not power on or accept charge." Battery shows no sign of charging when charger is plugged in, nor does the board show any signs of life when battery is unplugged and charger is plugged in. No light from the LED at all or any other indications of activity.

      Board seems to have no shorts, all power rails are fine and show high resistance.

      When charger is plugged in, voltage is present in 3.3V rail but absent in others....

      MPJA 10 AMP @ 0 to 30 Volts Switching Power Supply Cap Fault
      by sam_sam_sam
      I have this 10 amp 0 to 30 volt switching power supply that decided to have a 630 milliamperes draw on it at 0 volts

      I open it up to find non brands name capacitors in it

      I am not sure how this switching power supply is set up

      Could someone please explain how this power supply works

      Here is the capacitor ESR results

      (1) 47uf@50 volts 0.46
      (2) 47uf@50 volts 0.45
      New 47uf@50 volts 0.35

      (1) 100uf@25 volts 0.34
      (2) 100uf@25 volts 0.35
      New 120uf@50 volts 0.08

      (1) 220@25 volts 0.13...

      Philips PSU (715G7350-P01-000-002S) behaving funny
      by hervou
      Hi all,

      I'm becoming crazy trying to fix the Philips TV of my old man (model 43PUS6201/12 - the TV, not my dad). I've read again and again discussions about this and similar TV models, on badcaps (thanks so much !). I see no other option than asking for your help.

      The symptom is simple : when I plug the power cord, the red "stand-by" LED does not light on anymore, and the TV powers-on neither with the remote control nor with the rear button. I guess at this point you immediately think at the 5V (or other voltage depending on the hardware) stand-by output......

      Why doesn't current just bypass faulty capacitors.
      by Spudgun
      Hello esteemed members. I appreciate that my question will strike some as being somewhat childishly simple, but it genuine perplexes me! I have repaired several laptops before by removing a faulty capacitor that was short-circuiting the motherboard, whereupon the laptop would then work. For me, it begs the question that, if the current can bypass where the capcitor was when it has been removed, why didn't it just bypass it when it was present and faulty,? I can't get my head round the premise that if the other side of the capacitor is connected to ground, then why doesn't the current simply bypass...
