So I got my hands on a broken RX560.
After measuring the basic resistances and voltages everything appears to be fine, the core itself also heats up and the pc boots up (beep is there, on igpu mode everything runs fine).
But I just do not get any display output. After looking and touching around a bit I recognized the VRM controller chip (ON NCP81022) and the corresponding low side MOSFETs for the Vcore (uPI M3098M) get very hot to the touch.
Now I dont have the time anymore to check for any short circuits by injecting voltage in the circuit and checking if anything is not right so I thought I might just ask here for any ideas or information.
I measured 0.9V for the memory controller voltage but that appears to match with the coil which provides the voltage directly to the memory modules.
For the core I got 0.8V and I am not certain if that is an expected value or a rather low one.
I would appreciate any insight or ideas what might be wrong with my card.
