Please share the schematic or boardview files for this Mainbord. Got a fried chip/device on the mainboard, and would like to fix it, and check the other both near the fried chip too.
I need to know the model and type of this fried device. Its maybe an capacitor, but am not sure.

Thank you very much!...

Eventually discovered a burn mark near lower corner of LCD. Here is a summary

• Backlight on, no image
• Disconnect right buffer board (view from front), left side display comes on
• Masked off pin 7+8 (both ~12,5v on both left and right buffer board) from t-con to right buffer board (view from front) display works but have some lines
• Buffer board is pretty simple

Removed the front bezel to examine edge of the glass. Found burn mark on lower right (view from front). Plastic bezel covering the burn mark region shows heat signature on the inside surface facing the LCD panel. Last 2 pics. Bright...

Hi all, Im working on a board, that my customer brought to another shop, and smeared liquid metal all over the board.
The laptop powers on, then shuts off. I noticed traces of Liquid Metal near the edge of the CPU, but I fear some maybe underneath.

Has anyone ever tried Ultrasonic cleaning, or compressed air to remove or agitate the liquid metal?

Hello, this is my first request on the forum. If you need anything to contribute, let me know.

I need this firmware
IT8259E248A for the RGB functionality of the keyboard. If you have it, I'll need the EC for the IT5125VG-192 as well.

Hi everyone,

Sorry for the person who’s going to read all this !
I'm on a Nintendo Switch Lite, motherboard HDH-CPU-02.

While replacing the left joystick, I had to remove the motherboard to access the connector underneath. When I lifted the LCD connector latch, it broke (the plastic had become brittle over time), so I replaced the entire connector.

During the desoldering of the LCD connector using hot air, three small components located just below the connector (likely 0402 capacitors) came off and remained stuck to the bottom of the...

I replaced the backlights all good. Two months later set was dead, had a shorted D9100, replaced all good again.
Now months later set powers up,backlights light ok,no picture. 12volts missing from fuse on tcon. 12VA on power
supply is 19 volts. Changed D9100 again, same, 12 volts measures 19. Am I looking at a power supply or mainboard
issue. Set will power up with remote but not power off....

Good afternoon, colleagues. I have a Lenovo ThinkPad S440 with the 1-3-3-1 beep sequence. I've seen videos about removing the memory because it won't connect properly, but that's not it. I don't know if the issue is with the internal memory, and I was wondering if anyone had a way to disable that memory and test if that's the case.
The power-up sequence is that when you turn it on, it makes those beeps, and the fan and the laptop turn off.
My suspicions are either the CPU or the internal memory. Has anyone had a computer with similar problems?
I'm adding information. I've seen...
