    I actually have a thread which is very old. I just gave up then, but I may revive it. Need to find it, and do some checking.
    I have a 87V(the only one that I have purchased new), 189(old version, that had deposit in the terminals and it was beeping)), Siglent SDM3055(got it from scrap from work, with a boot issue, that I have just revived w/Siglent provided firmware), Amprobe 38XR-A(had a blown fuse). No shortage of meters.

      Anyone know how to take apart a Fluke T100 Voltage Tester without damaging it?
      by cheeky2
      See attached picture. I have a Fluke T100 Voltage Tester that the resistance and diode measurement isn't working (it's not the batteries (as I have already checked them and put decent Duracell 1.5V AAA batteries inside it).
      I have looked on the web for any information and on youtube without any results for this model.
      There are no screws visible or anything obvious. So I am hoping someone here has the solution to take it apart?
      The only way I can see is underneath the yellow rubber handle area, however I don't wish to damage it if it isn't the case!...

      Lenovo L490 Ram voltage circuit malfunction
      by rddube
      Hello friends,

      Looking for some guidance here. The RAM voltage circuit on this motherboard keeps burning out PU301 which is a RT8231AGQW. Copy of the board with the burnt chip attached with some voltage measurements and copy of the schematics also included.

      I think I've checked almost every component in the circuit, but when I change the RT8231, the laptop starts I have 1.2V on the inductor for about 10 seconds and then the RT8231 goes south and no more voltage on the inductor. All other voltages on the laptop are good, this is the only one conking out for a reason I...

      Panasonic TH-L42D25A checking the PSU output voltage
      by electron_jj
      Hi Everyone, I am new to this forum. I have a Panasonic LED TV which doesnt turn on and is blinking 4 times repeatedly when I turn on the switch. The TV does not respond to the remote control so I had to turn on using the physical switch on the side of the TV. When I turn on the switch the 4 x blinking starts and repeat itself until I turn off the TV. There is a black screen. I turned off the light in the room to check the panel and I think there is no backlight as far as I can tell.

      I have been inspecting and testing the capacitors and diodes in the power supply board to try to...
