Laptop Lenovo T450, uszkodzony był bezpiecznik na płycie głównej (F7) i kondensatory w matrycy (b140xtn02). Po naprawie matryca podświetla tylko na zewnętrznym zasilaczu, na baterii nadal brak podświetlenia, podejrzewam dalej matrycę.

Hello!

The matrix backlight controller chip AUO L10216 is very likely damaged and needs to be replaced.

Note that this chip requires programming. It will not work, if you solder a brand new (blank) chip. It's best to "pull" a replacement chip from the old broken matrix. The matrix model from which the replacement chip was "pulled" is usually not critical - you can use a chip from any matrix with the same backlight controller chip.

Yes, you can try, but probably no one can confirm whether it will work or not without a test.

Be careful when using a hot air, as there are source driver FFC cables glued to the opposite side of the board.

Układ AUO L10216 wymieniony z innej matrycy ale ten sam objaw, nadal brak podświetlenia na baterii, matryca zachowuje się identycznie jak z oryginalnym układem. Pozostaje wymiana matrycy na nową.
Dziękuję za pomoc.

Try with another matrix to test to make sure that the problem is really the matrix and not the laptop motherboard.
