I'm trying to identify this SMD component. If I'm not mistaken, what's written there is "23F"

Device: Laptop

Model: Toshiba Satellite C850-P5010

SMD Location: Near display connector

Problem: White screen

Can you help me identify it?

    \$\begingroup\$ Look around on the board, chances are it’s used elsewhere too since single lines on the BOM tends to be replaced by something else to satisfy the bean counters. \$\endgroup\$

  • \$\begingroup\$ Are you sure it's 23F and not 23P? Hard to tell from the picture. \$\endgroup\$

  • \$\begingroup\$ @nanash1 , No I'm not sure. Just guessed. The component had a short so it's hard to read what's written. Btw thanks to others for the response \$\endgroup\$

The markings could match with a Diodes Inc DMP2305U if the actual marking code is "23P" which, I think, is plausible from the picture. The style of the markings looks like Diodes Inc to me with the rotated date code (barely visible in the picture), but they don't have a part with a "23F" code as far as I can tell, only "23P" and "23X"
