I have an ASUS ROG Strix- G513IH-HN008, motherboard G513-6050A3249301- MB-A04 (A4)
When I received the device, the device has no function. After an investigation, I found that the PWM CONTROLLER RT6575B (U6100) is getting warm and there is a short circuit at the 3V3 output. This normally supplies 3V3 for the embedded controller IT5571E-128 (U301). When measuring and analyzing with a thermal imaging camera, I found that some components are damaged: SLG4E42553VTR (U8500), IT5571E-128 (U301), LAN RTL8111H (U450), LOGIC 74LVC1G08GW (U1900), RT6575B (U6100) All these components are on... -
Hi there,
I'm looking for anyone who might have information on Apple's embedded Apple Watch charging daughterboard, ID 820-02601. This is currently used by Anker in their Apple Watch charging products, but likely by other Apple partner brands as well.
You can see the board referenced in ChargerLab's teardown of the Anker Y1811 3-in-1 MagSafe cube - they discuss the "Apple Watch wireless charging circuit" about 2/3rds down the page. It's not pictured, but the board ID reads 820-02601-A, which sure sounds like Apple.
This daughterboard uses an interesting...04-21-2025, 11:41 PM -
Comrades, I have a task for a DIY project to connect the display from VivoBook T3300K to a separate DIY device. There are no problems with eDP, I found a scaler for the ATNA33 OLED matrix, but with the touchscreen it’s more difficult, I need a diagram to understand how it is connected and works in order to try to connect the touchscreen to another device via USB -
Hello,
I have problem with my graphic card GV-N3060GAMING OC-12GD.
2 smd elements are missing.
I've already bought a boardview but it's not complete - that specific area is not attached. I tried with different similar models but without success.
This is my PCB
And this is screen of boardview
As you see those missing capacitors or resistors are not on boardview.
Also i compared every single transistor from boardview to real card and everything is related.
It seems that this one is like extra.
Could anyone...08-09-2025, 10:26 AM -
Hello, I have a Quadro RTX 4000 graphics card with a FAN problem.
The fan immediately spin up to 100%. I checked the TACH pin on the fan connector, and there is a direct short(44Ohm) to ground. With the fan disconnected, the short is still present, so the issue is on the PCB, not in the fan itself.
I traced the TACH line and checked the nearby pull-up resistors — they all seem fine. There are no visible burned components. Close to the fan header there are chips like NCP45491, uP9512R, and uP1666Q, but as far as I know, they are VRM/power monitoring controllers, not...10-01-2025, 01:05 AM
