Greetings!
Can someone help me identify this burnt component on Bobcat 300 helium miner. Thanks!

I ordered this and it is working ok...so if anyone need this information here you go.

First post -Intel NUC 10i5 -BXNUC10i5FNH not powering on -IC burnt- request for IC details/datasheetHi all,
I came across this very active forum with knowledgeable folks on electronic circuits and components, while google searching for the details of my burnt IC marked 7603 in Intel NUC board. I joined this forum today and this is my first post here.
I recently got an Intel NUC 10i5 and had installed Linux Mint and was using it for about a month when it died suddenly and did not power up after that.(Power Adaptor is ok). When I opened the NUC , there was a burnt IC marked 7603 (and ILCB in second line). I am unable to find the details/datasheet of this IC. I will be grateful if... -
Hi guys
This Zotac GTX 260 had a high side MOFET on one Vcore VRM phase short circuit Drain to Gate (Not short Drain to Source)
This has burnt out the drive IC L3E (ADP3110A) and also an SOT-23 device very close to the driver IC. According to the PCB markings 'Dxxx' this is likely to be a diode.
Basically the VRM has 4 phases, two powered from one 6 way connector and two powered from the other 6 way
I would assume each pair of phases are basically identical, the burnt out phase has SOT-23 devices WW1 plus the burnt one.
The good phase... -
Hi Dear Friend., I am working on a Apple MacBook Pro A2338 820-02773-A. The history was that the AON Rail on the Trackpad connector JT400 was burnt. After I removed the burnt connector, I tested with the meter & no shorts. Connected the USB C power & all booted fine, no problems at all. I soldered a New TP connector put in the old trackpad with a brand new Flex cable. The laptop beeped in the start but no display. I removed the connector & the display was fine again. USED a known good Trackpad & a Flex cable, even with this still the same problem. I checked the connector whether... -
I picked up this used Bose Acoustimass 10 IV speaker system. Speakers seem to work fine, but the subwoofer does not make any noise. So I took apart the unit and found some obviously failed (burnt) components:
- 1x 3.14 A @ 250V main circuit fuse
- 1x bridge rectifier GBU601. there's actually two of these on the board, one is obviously burnt and the other does not seem to have any anomalies like shorts. However I figure may as well replace both.
- 2x diode. This is tricky because the only markings I see on it are: "617 402". No current rating or anything else.... -
I've got a 240v LED uplighter which isn't working. Pulling it apart shows a clearly burnt resistor on the circuit board, and I'm hoping some of you will have suggestions on what to replace it with. First, here are some photos. Power comes in, through the fuse and choke, then through the big blue variable resistor labelled B500K (ignore the similar blue component at the bottom - it's a simple switch for an attached reading lamp). It then passes through the burnt resistor (or at least did once), through diac DB1 and the unburned 30 ohm resistor to the gate of the triac.Now I assume there's a simple...
