    Bad cap or not ?

    Hi

    Here is a capacitor inside a faulty Moog MF-104Z delay pedal. What do you think ?

    I -might- have fed the unit 15 volts instead of 9v....

                      Janome DC3050 Sewing Machine Pedal Resistance
                      by CG2
                      OK, this is a long shot. I got this sewing machine cheap because it's end of line, ex-display, and had no pedal. The genuine pedal costs £60, while Ebay knock-offs go for around £15. So I went for the knock-off, it doesn't work, and I'm not sure whether it's the pedal or the sewing machine that has the problem.

                      Now this is an electronic machine, unlike the old fashioned sort where the pedal was a big resistor in series with the power to the motor. Here, the pedal is just (I think) a variable resistor fed with a 5 volt supply, and limited to a current of 5 milliamps. Assuming that...

                      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

                      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......
