Model: Lenovo ThinkPad X250
Stara płyta główna
Motherboard: VIUX1 NM-A091, Rev.: 1.0

APU: Intel Core i5-5300U

Hej:
Mam lenovo x250 gdzie padło podświetlanie matrycy.
W płycie głównej wymieniony bezpiecznik F7 i dalej lipa.
Nowa taśma. Nowa matryca. Ostatecznie nowa płyta główna i dalej nic. Na
innym laptopie matryca świeci. Na tym już nie. Podłączane kilka matryc.
Żadna się nie podświetla, w innych urządzeniach działają.
Proszę o pomoc :frustry:

Włącz laptopa do ustawień BIOSu i zmierz napięcia do masy na pinach:
- 13, 23, 24 i 26 złącza J10 (ekran),
- 2 i 22 złącza J11 (touchscreen).

Powinieneś wymienić bezpiecznik F1, a nie F7, on jest po drugiej stronie płyty w mało typowym dla matrycy miejscu.
Sygnal VBL.

___________
Zobacz jeszcze, czy nie masz kabla zlego kabla do matrycy z touchscreen lub wersji hd/fhd.
Wtedy też może palić bezpiecznik.
