Identifying and Replacing component "Q9" on Asus VG278Q
I have an ASUS VG278Q 27" 144Hz gaming monitor that recently crapped on me.
I've found the part that failed but am having difficulty identifying a part number. Haven't had any luck looking up part numbers through googling.
This form factor tends to be a MOSFET, voltage regulator or diode . I'm guessing transistor based on the Q9 reference designator but then it makes me wonder what kind? NFET or PFET? Or even BJT?
The only things I can seem to make out are "21..."
Any suggestions on how to find the replacement part?
Es esta una buena pregunta?
