820 3476, Short on PP3V42_G3H

[Noguinfor]

Hey guys,

Working on 820 3476 with short on PP3V42_G3H!

more precisely i have a short on pin 2 L7095. With my Power supply i put a wire with 1V on pin pin 2 for find the bad component and only heat r8131! But the stupid think is i remove the R8131 and when i put 1v on L7095 the pin 1 off r8131 keeps burning. when i put ?lcool isoprop?lico on area off r8131 i can see the alcohol evaporate at the pin1 off r8131. I don't have others components heating on this board!

Already replace U7100 for a new one and same history!

How do I find this short??

Thanks
