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... -
I picked up this Precision 5550 to fix up recently, and found that the ISL9538 chip was burnt on pin 14 (CSIN). The two left side Type C ports negotiate at 20v, and the right side one only negotiates at 5v. I also found the EMI protection diode, DT35, was burnt on that side. I pulled the ISL9538 off, checked for any other obvious shorts, repaired the pad, and put a new one on. Now, I still do not get power, and there is a rapid clicking sound from somewhere on the board that I can't pinpoint.
Here are the voltages measured at that chip:
To note, DCIN at Pin 17 is low,... -
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.... -
Could someone help me identify the two rezistors burnt inside this AL539 device from Autel, i cannot find any dissembly pictures and there are a lot of these devices, i hope some of you have it 🙌
