Title: Asus VE276Q monitor with unidentified burnt component
Post by: dangerj on August 01, 2019, 12:40:38 am

Hi !

I have an Asus monitor (model VE276Q) that wont power with a burnt component on one of the pcb in the back. The component seems to be some sort of ic labeled 4616 BA1N17.

I've been researching the component on sites like Digikey and Mouser without much luck. I've also tried to find schematics or diagram of the monitor without finding anything.

The component is on the side where the power comes in.

Do you guys have any idea what the component might be and where (if possible) could I find it?

If needed I can post higher resolution of the PCB.

Thanks a lot!
