Does this mean that this second IC U5110 is also damaged?

Why?
I have no idea what is diode mode to ground reading there...

ah sorry I don't understand u...

value=806

thanks

Post actual U5110 voltages (all pins).

 

[lincev]

U5110
1 PP3V42_G3H= 3,39v
3 PP3V42_G3H_SMC_SPVSR=3,39v
4 SMC_MANUAL_RST_L=2,74v
5 SMC_RESET_L=3,33v
6 SMC_LSOC_RST_L=3,38v
7 SMC_ONOFF_L=3,38v
8 PP3V3_S5_AVREF_SMC= -0,13 (Using the positive tip of the multimeter the negative symbol appears)

If no short, then this U5110 is also bad.

nice, it already works perfectly, third time's the charm...

bad luck three times damaged IC from different logic boards

Thank you and sorry for causing so many problems
