    "short killer pro" Component identification help

    Hello friends,

    I have a device called "short killer pro". It becomed damaged. Now, after changing 4 ICs it is working again, BUT I don't have neither voltage and intensity reading in the front display (the adjustments are working fine both for V and A, but there is no indication, as I said before). I did not find out any firmware update for the Altera microcontroller it uses (the rest of the functions are working, but the buzzer, for example). And I am suspecting about this IC, but I am not able to decipher which one it is. I see it is from Texas Instruments, but nothing more. It is a SOIC-10 package. Please, if somebody of you can help me to know which one it is, it will be great. I will include a pic with the IC. Thanks in advance for your help, as ever!.

                  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...

                  CKV Short Killer
                  by kevin_allein
                  Hi, recently I found a lot of videos on YouTube regarding CKV Short Killer. All of those Videos seem to be from Asia (e.g. in Hindi). I could not find a single English Video. Translation on YouTube on those videos does not work well, so it is hard to understand details.
                  Basically it seems to address the frequent problems of LCD panels, when CKV and CKVB lines have some short and the only fix is to cut those lines or use tape on the ribbon cable to the secondary scalar board of the panel.
                  Does anyone have any experience with that ?

                  MacBook Pro 14" A2442 Short on PPBUS_AON but no short present when injecting voltage!
                  by Stephen
                  I check PPBUS_AON and there is a short present on the line, the computer shows a short when testing for short to ground, so when I inject voltage into the line, I get 0AMPS so no short is showing up. I have replaced a blown cap on this board that exploded and tested for the short and it is now removed. Any suggestions? I tested voltage at the line when the fuses are connected and I am getting 1.2 Volts at the line.

                  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...
