Re: RCA RLDEDV3255A burnt L1
see this thread https://www.badcaps.net/forum/showth...=inductor+core
Likely need to replace the fet and possibly the drive ic.Last edited by R_J; 04-25-2019, 08:51 PM.

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,... -
Hi guys
Can anyone identify this component U100
See the video at 38mins 20secs (microscope close-up)

It connects to the SMRESET signal coming in from the PCIe pin 11 and is presumably a logical AND gate or dual transistor/FET
Thanks

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...
