Hi,
I have a GTX 1070 FE card where the components LB12 - LB 15 have burnt. I wondered if anyone have any information on what these components are?
I was thinking power Inductors for AC filtering, but it's difficult to find any information on the specifications. I measured 4 ohm across all the components before removing them from the board.
After removal i can measure a variance from 4 ohm to 1,2kOhm on the components (i guess the high resistance is because thay have burnt).

Any information is helpful.

The components are located in the bottom right corner of the picture.

Thank you in advance for helping.

Best regards,
Victor

don´t you have warranty on it? Just RMA the graphics card where you got it from or from the manufacturer

the components should be fixed Inductors, but without values and schematics, it´s nearly impossible to replace these with the correct components.
