    I want to intentionally short out a transistor for testing. How can I do it safely?

    I bought a cheap component tester that identifies transistors, diodes, fets, caps, and other things. So far it works good for components that are not broken.

    I want to see how it performs with broken/shorted components. If I were to pull a transistor off of a junk board, how could I cause it to short without melting it or starting fires? How about a MOSFET? Diode?

    You can use 10 Ohms resistor in parallel with for example; the Emitter and the Collector of the transistor to simulate resistance leakage but not dead short between C and E, your tester should show that it is bad.

      Extreme High Current & Low Voltage Short Killer ??
      by DynaxSC
      Hi Folks

      I'm looking for a extreme high current short killer solution for a reasonable cost.

      I have an LGA1700 motherboard (ASUS PRIME Z790-P WiFi) where I exchanged the LGA socket already 3 times, and every time after the socket exchange I get a short of power supply lines VCORE (V variable) and VCCIN_AUX (1.8V).
      After taking off the socket, the shorts dissappear again.
      The soldermask on the socket is already partially demaged from the heat, so I have reconstructed the soldermask by manually painting the missing soldermask parts with a very small top of a...

      HP Victus 15-fb dag3pamb8d0 Short on VCORE – How to Confirm CPU Fault?
      by adelfr2009
      I have a laptop HP Victus 15-fb with motherboard DAG3PRMB8D0, CPU Ryzen 7535HS, and GPU RTX 2050. The laptop has a power issue: it does not turn on at all, and there is no light on the DC jack.
      After inspection, I found that an NMOS near the charger input had a short. I replaced it, but the short remained on the 19V line. I checked the charging circuit and it was fine, but the short appears after the current sense resistor near the charger. The charger does not pass current when connected, so I inject 3V–4V after the sense resistor. No component gets hot, except the CPU which becomes...

      Samsung PN51F8500AFXZA, PSU BN44-00619A, Short QP802S, ICP801S testing/sourcing
      by DXseekerMO
      Hello everyone!

      So from the free pile yesterday I got a Samsung PN51F8500AFXZA that wouldn't turn on. Stand-by light did not illuminate. Found fuse FP801S open, the DC legs of both Bridge Rectifiers shorted and MOSFET QP802S short drain to source. Removed QP802S and short on Bridge Rectifier cleared. Confirm QP802S is short drain to source. No short found on QP804S.

      Control IC ICP801S is TI SPC1012T.

      Questions:

      Is there a way to test ICP801S with a multimeter for short/failure?

      Neither DigiKey or Mouser stock SPC1012T....

      guys..i need help with this lcd display used on ebikes pls.
      by vikivng
      This is an lcd display used on ebikes.
      long story short, there was condensation inside the unit.
      I opened it and thoroughly cleaned the pcb with isopryl.
      The board had no visible corosion.
      It powered on fine and was tested for an hour or so.
      However when connected to the bike,,it did not power on at all.
      I took it home and reopened it to take a look. There are no shorts based on MY testing.
      However,,when I probe the transistor and the mosfet gate in diode mode or contuinity mode, (one probe on transistor collector and one probe on mosfet gate}the unit...

      Acer Nitro 5 LA-L181p power LED turns on by 5 secs (Short on PCH rail?)
      by Victor Moreira Silva
      Hello everyone,

      I'm trying to repair my old Acer Nitro 5 (AN517-54-55T5). I've already bought a new laptop, so this is more of a learning project. For the experience, with no high expectations of success.

      Well, my decice specs are the following:

      Model: Acer Nitro 5 AN517-54-55T5
      CPU: Intel Core i5-11400H
      GPU: NVIDIA GeForce GTX 1650
      Motherboard: GH51G LA-L181P Rev:1c

      The symptom:
      When pressing the power button, the power LED lights up for about 5 seconds and then turns off. Initially, the issue was intermittent: sometimes...
