The resistor was measuring correct, but I replaced anyway, and for some reason it made a difference.
R8123 Replaced
Pin 12 – 5.14V
Pin 15 – 4.93V

Those are the only pins with voltage.

Pins 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 13, 14, 16, 17, 18, 19, 20 – 0V on all of than.
Pin 12 – 5.14V
Pin 15 – 4.93V

Diode on Pin 2 is not normal if compared with another boards. Not same boards, but I think it should at least be similar.
Pin 2 – 0.054

Didoe mode reading at L8100 may differ; depends by RAM size and CPU type.
You may have a problem, I don't have similar board for comparison.
However, if you get big difference comparing with other boards, I suspect CPU.
If RAM chips died, CPU is affected for sure, being more sensitive.
