Ok, i didnt know where to post a subject but just the information for everyone in the future...Msi is really strange... There are two versions of the motherboard with designation MS-16jb1 ver 1.0. first one is with i7-6700 cpu and sr2c chipset and second with i7-7700 and sr40 chipet. Beside that the boards look identical...and they both have same designation MS-16jb1 ver 1.0. both are ver 1.0. I know that pins are the same on 6 and 7 gen cpu and chipset but they should be distinguished at least with the ver. of the board. I never seen this before. So info is for all to be careful in the future.

Mostly i use 90x90 stencils for chip reball, then i remove stencil and apply heat with heatgun...and preheater...and everything is fine. But this SR40 pch chips are very small with lots of balls half milimetar from each other...and i am not happy with results... I get bridges and so on....So i was thinking maybe to reball these SR40 chips with direct heat stencils...but i can not find it in 90x90 size. I tried aliexpress and ebay...but nothing.
Maybe someone knows place to buy? Thx -
Hello
I received a treadmill controller (probably Zipro Dream) for repair (more like replacing parts). Board designation: PCB-ZYXK9-1111-V1.2.PCB. existing in it were:- mosfet Q9 (originally MDF4N60 was installed) - mounted on P10NK60ZFP;
- resistor R64 (replaced);
- F2 protection.
After turning on the power of AC1 and AC2, the components burned again. The existing elements were desoldered and new ones were soldered. The controller has not been connected yet because I'm afraid they would be destroyed again.
There are no additional restrictions that can be applied,...02-26-2025, 02:29 AM -

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,... -
So today I was checking on a GC board that I got from a friend and he told me the GC would get an error and doesnt want to read games after a couple of hours gaming on it. So I suspected it to be some bad solderconnection or an capacitor, when checking the solder connections of various components one of them was so loose that it flew off. I think the component right next to it is the same. The board says it's DA15 and I've never heard of that designation. The Text on the component says A1, and this also doesnt help me out. Maybe one of you guys knows what part that is so I can order it instead...
