    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...

          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....

          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...

          Help me find the short circuit on this WORKING Nvidia GTX1650
          by aaronkatrini
          Hi all,

          Recently picked up this GTX1650 at a local flea market for a low price and wanted to use it on my secondary PC. I first tested the card and saw the fan spin for a split second and then nothing. Immediately I thought of a short circuit. Disassembled and found a shorted SMD capacitor, injected voltage into it (1V/4A) and two Mosfets got hot immediately (QN3103 & QN3107). Desoldered these Mosfets and the card turned back to life.

          Bought replacements from Aliexpress and replaced them afterwards. Tried the card but still the saw the fan spin for a split second...

          PHILIPS 40PFL7007 TV DEAD. D501 testing SHORT on DMM
          by vikivng
          Hi guys pls can someone help with this set..
          Tv doesnt not power on.
          No standby light.
          There is a burn mark by the leg of D501 diode.
          The diode tests short in both directions.
          I have been reading this usually means the diode is faulty? As normally would be open.
          I have not yet taken voltages since this is obviously short I would like to replace it.
          Can someone help me with a substitute for this diode since it seems not to be the standard type?...
