help identify shorted part...acer nitro 5 FH51M LA-J871P

[dqtech]

this is gpu area....part that i mark with red colour is short to ground....how can i check either GPU chip it self or only caps has been shorted yaa?

GPU operating voltage is low. By design, the gpu voltage rail will have a low resistance to ground.

What is the exact resistance to ground of these areas? No power to the board during resistance checks.

resistance read 0.00ohm sir

Inject 1 volt (max) onto this power rail. Hunt for who heats up. If it is the GPU, the gpu is dead.

okay sir...understand

Very unlikely. These new age GPU will show very low resistance to GND. Reading as low as 0.1 ohms may be good.
Are you measuring the gpu coils in diode mode?
IF yes, shift to resistance mode(scale set to 200 ohms) and then again read the value.
Before measuring, check resistance between your multimeter probes by shorting them.

im using resistance mode sir....diode mode also read 0.00....resistance mode read 0.01@0.00ohm....i did try inject 0.5v and feel heat on top of gpu chip...thats mean gpu chip is dead right?
