I don't understand it right now...but... I measure on the PU201 at pin 5 (LDO) against ground 1.9 ohms.
The PU201 also gets hot. I just don't understand why I was able to measure 3V there last time. Shortly before I noticed that the PU201 was getting very hot, I was able to measure 5V on the PJ204, i.e. the missing +5VALW. However, only for a short time, then 0V.
The capacitor PC208 is located at PU201 pin 5
(4.7U_0603_6.3V). Unfortunately i tried to measure the capacitance with my multimeter ... OL appears.
The capacitor only has a resistance of the same 1.9 ohms like Pin 5 to Ground.
Is the defect more likely in the compensator or is the PU201 defective?

I unsoldered the PU201 and the PC208. Unfortunately the resistance is still 1.9 ohms to ground
I measured all pins on the UE1 that have 3VL. Pin 26 has 0.0 ohms to ground. At all other pins (50,92,114,121,106,127, ...) it is 2 ohms.
Is it correct that the UE1 (IT8996) is defective? In that case I give up because it needs to be programmed.
By the way: 5V LDO has several k-Ohms to ground

I tried some more here. I replaced the IT8996E with a programmed one.
I have all voltages, so the 3.3V / 5V / 20V / 9V / ...
It also seems to start, it consumes 0.9 amps after starting and continuously.
Unfortunately there is no picture. The +LEDVDD (almost 10V) are there.
Unfortunately the +LCDVDD_CON that comes from U1 is missing.
3.3V arrives at pin 5. Unfortunately there is 0V on the EN pin.
The resistor R3 has 97kohms. No short to GND.
APU_ENVDD_R has direct contact with APU_ENVDD and that comes from the processor.
Is there anything else I can check there, or is my processor broken?
