Just archiving everything related to bumpgate since most stuff has disappeared from Google. Maybe people will finally take the time to read some of it and stop shouting "reflow gpu" at every occasion but rather try to understand what the real issue is…
Interesting parts about the failure analysis are "Why Nvidia's chips are defective" and "Why Nvidia's duff chips are due to shoddy engineering"


May complete this post at a later date with more details.
Basically issue is a combination of thermal dissipation of the chip with hotspot,...

Hello everyone!

Please help me determine which microcontroller was in this place.
Logically, I guess that this is a ddr4 PWM memory controller and some kind of Richtek, but which one?
Thise motherboard came after another service, where they say that water got on the controller and it burned down and they dismantled it.
They did not take photos before the intervention

The DANJLFMBAB0 REV B board, schematics, boards and photos of the motherboard were not found on the network, but I may have searched badly-((
Maybe someone has a photo of this piece,...

Hi all, i'm asking all to reduce photos to a more comfortable resolution before post, the better like around 2000x2000, otherwise many PC / Tablets / phones refuses often to load them or has strong defection... today's digital cameras integrated in phones especially are a mockery because them saves photos at enormous resolutions with much less the real definition, so reducing them is only a good deal.. THANKS!!...

I have here a Cambbridge Audio Stream Magic 6 which does not power on.
When opening the case the PSU appears to be faulty:



IC1 (ICE3BR0665J), D2, the rectifier bridge, C15,C16 are dead and T2 is fried:




I found the schematics of the PSU in the cambridge Audio CXN Service guide which uses the same:
My problem is that I cannot find any info on T2 (SG01323) which seems to be a choke. Anyone knows how I can find a replacement & the value of that choke ?





Thanks very much in advance...

Hi All,

My WD external drive I used to use for my backups recently decided to go belly up on me so I've been playing around with different bits of software to try see if I can recover it and just wanted to get some advise on which programs you guys have the most success with.

Yes I've cloned the drive and no I'm not paying a grand to take it to a professional. If I can get some stuff back great, which I have, but there's still quite a lot I haven't. It's not worth taking to a professional though it's only my programming courses and vacation stuff so it's a nice to...
