A1502 820-3476-A

[pipsystems]

Hi again, I have an A1502 board that started at 26mA for a while, I was testing voltages and at some point, it jumped to 150mA

I was originally missing PP5V_S4 on L7520 but then once it jumped to 150mA it was present.

L7320 & L7310 seem a little low at 1.7V instead of 1.8V?

U1950 there is no pp3V42_g3h but checking L7095 PP3v42_g3h is present.

I have also attached thermal images of the board

Thanks for your help

Broken trace to pin 8/U1950; rebuild it.
Post voltage at all its pins.

That was the problem, thank you.
