 Forum rules: Click here to view the forum rules

  1. Topic title should contain: the device's manufacturer, full model and the brief description of problem.
  2. Topic message should contain: the PCB marking code (required in case of hardware repairs), an extended description of problem, things you have checked/replaced/measured, your conclusions and the question. If you are not able to find the PCB marking code, please read THIS TOPIC. If you still cannot locate the PCB markings, please upload a clean, both-side photos of the mainboard - it is required to remove any films, modules or brackets possibly covering these markings.
  3. Before posting a new topic please read all topics in TRAININGS subforum and make a preliminary diagnostic based on the content of those trainings.
  4. Uploading of any complete schematics, BIOS / firmware files or any other kind of documentation, or linking to 3rd party websites with such files, is STRICTLY PROHIBITED. You can only upload the small portion of documentation or, link to BIOS file on UNVERIFIED BIOS FILES subforum, which simplifies the diagnostics/repair. You are not allowed to upload more then one complete page of instruction/schematic per single topic. The file you upload must not contain any watermarks, "confidential" markings, links or email addresses and cannot be password-protected.
  5. It is only permitted to describe one faulty device per single topic - you should always open a new topic for each subsequent device.
  6. Requesting of the full schematics, BoardView files, BIOS files or any other kind of documentation is NOT ALLOWED in this subforum. If you need to ask for any of these, you should open a new topic in DOCUMENTATION/BIOS REQUEST subforum.

Hello!

Clean this area of the board with IPA and post a clear picture with visible copper traces connected to this resistor.
Also post a picture with visible markings on the QFN chip next to this area.

Top and bottom side. Red and green are only connections to this resistor (black GND). Chip marking "MPS1935 MP2949A K2625588X".

edit:
Green pad is connected to VIN. Resistor connected to ground is 133 kΩ. Maybe my resistor is 2 MΩ (like on ASUS GX701 or ACER ZGL next to MP2949A)? But is not connected to pin47 of MP2949A here.

Check, if pin 3 of the transistor marked "72K" is connected to pin 47 of the MP2949A.
If so, the value of the resistor you are looking for is definitely 2MΩ/1%, package 0402.

Transistor "72K" pinout:

Yes it is. I replaced it with 2MΩ 1% .Now I have 0,82 V on cpu coils and picture on the screen.
Thank you again MATIC!
