Ip28 motherboard repair

Ip28 motherboard repair
Hi! I want to try to repair a ip28 motherboard, I think is a overvoltage the cause of damage (I didn't damage it)

I have the working ip22 (it's almost the same) I have tested the power lines and is all ok... except the pin 5 on j10, on ip28 is present more resistance, I presume the issue is here. (5v standby)

Not exist any schematics of ip22/ip28? Multilayer pcb is very difficult to reverse engineering...
