    [SOLVED] Need help to identify the TVS Diode - Samsung EVO 850

    I definitely can't consider this my best work, but it seems to have done the job! The first time I must've overdone the soldering and had no luck, the 5V pins weren't visible anymore. After removing the previous soldering (hence the burn stains around), I was able to place a more accurate blob...

    Okay I'll look into getting the 5V pins connected through a wire. I currently don't own a soldering kit nor an iron, so may check with neighbours or buy one instead.

    [SOLVED] Need help to identify the TVS Diode - Samsung EVO 850

    Before I exhaust myself and trying different things, I want to check if this is supposed to be the case. If we zoom in on the board itself, it looks like the wire near the 5V in and 5V out pins - that would connect the input circuit with the remainder of the board - is disconnected. I will...

    [SOLVED] Need help to identify the TVS Diode - Samsung EVO 850

    Okay clear. What resistance value range would indicate a short? and since we were able to determine there are no shorts here, the next step would be for me to create a wire link between any of the 5v ins and 5v outs, correct? And should this be applied to both sets of pins or just 1? Or was...

    I'm starting to get it more and more, though what indicates a short when measuring the resistance? When I use the 200 Ohms setting to measure the resistance, the value stays at 1 for all V1 to V8 points. The only exception is on V8 if I were to measure the opposite side (the left side instead...

    Measured the resistance, most of them are stable on a single resistance value, but 3 of them are peaking significantly, especially the longer I keep the red probe on top of them. V1 = Starts at 0.1M (100k) Ohm and increases to >1M Ohm V2 = 0.08M Ohm (stationary) V3 = 0.08M Ohm (stationary) V4 =...

    [SOLVED] Need help to identify the TVS Diode - Samsung EVO 850

    Okay so I've been able to test it using a different battery, that didn't make a difference, though I managed to figure out the issue. When using the 'V~' setting to measure the voltage, I get double the values. When using the other 'V_...' symbol to measure the Voltage, it gives me accurate...

    [SOLVED] Need help to identify the TVS Diode - Samsung EVO 850

    I'll be giving this a go either after dinner or tomorrow and update the thread. And yes it has a 9V battery. I'll make sure to check if using another battery makes a difference on the Voltage measurements. So far I haven't had a sign or warning of a flat battery.

    Possibly... This is what I get when I use the power supply tester: If the e-fuse died, what can I do to recover the data?

    [SOLVED] Need help to identify the TVS Diode - Samsung EVO 850

    Okay, measured the voltages from each pin, coming from the SATA power cable connected to the power supply: 1 = 06.4V 2 = 06.4V 3 = 06.4V 4 = 0 5 = 0 6 = 0 7 = 10.1 8 = 10.1 9 = 10.1 10 = 0 11 = 0 12 = 0 13 = 25 14 = 25 15 = 25 Shall I test the same thing using a different power supply and...

    [SOLVED] Need help to identify the TVS Diode - Samsung EVO 850

    Sorry I thought you were referring to the 5V in and 5V out pins near the e-fuse. Sounds like you are referring to the SATA power connector pins instead. Would you mind clarifying which +5V pins I should be measuring by circling them on the screenshot? Apologies for being such a pain...

    I've now also tried shorting it by conneting the safe mode points holes with tweezers, that didn't offer anything unfortunately, it was not detected and I couldn't hear the SSD "boot". Just tested the meter on 2 different 1.5V batteries. One was showing 1.565, one was showing 0.986. They may...

    [SOLVED] Need help to identify the TVS Diode - Samsung EVO 850

    Makes sense. First time I'm trying such a thing. Here are my findings so far: V5 in: Both measured at 10.1 V V5 out: Both measured at 04.0 V As indicated on the screenshots for the onboard power supplies: V1 = 0.00 V2 = 0.00 V3 = 0.00 V4 = 0.00 V5 = 0.00 V6 = 0.00 V7 = 0.00 V8 = 03.4 V I...
