Switch OLED screen shows no display, but touch works

I’ve got a switch OLED model that is in working condition other than it won’t display anything on the OLED screen.

It charges, touch screen works, it’ll display on a tv if it’s docked, etc.

I tried a factory reset and re-seated the display connector and it’s still doesn’t work. There doesn’t appear to be any visible damage on the board or connector, the ribbon cable for the screen looks good, and the capacitors near the screen connector seem to be fine.

I’ve done some other detective work with other repair groups online and I think it might be narrowed down to a DOS04 chip on the back side of the board underneath where the screen connector is. I searched for this chip online but can’t find an exact model match. I found similar ones on aliepxress and one of the listings mentions “light control” so I’m thinking I’m on the right track, but I have no idea.

So I’m curious if anyone else has had this issue? Any other ideas to test? I’m I out of luck for finding this part?

Appreciate any thoughts!
