1697 Controller won't turn with batteries.

1697 controller won't turn on when I use batterys, with batteries they don't show any signal of life, only work wired.
The problem is the button board., But where?
I change the button board and put in my MCU board and works fine.

Check that if L1 is on the board and/or look for a crack in the board that has opened the trace that L1 is on.

I make a check and the Trace is Ok,have any components in that trace that I should test in particular?

The schematic of the 1537 Button/Power board is the same, the 1697 just doesn't have the IR LEDs on it. You can use it to trace the AA+ line out. https://www.acidmods.com/forum/index.php/topic,43204.0.html

I find the problem, all traces are ok, but he don't turn yet.
SO accidently I touch the u3 with my finger and them he turns on, i put some of hot air there and make a "reflow", take out and put again and are work!
Thks for the help <3

Ok the problem is back, and not are the U3

I test every component with the scheme, and everthing is OK, but the controller still not working with batteries, i already change the battery, check the contact of AA+ and AA-, L1 have 2.71v and he trace to. this is a dead end?

and check the xbox button too.

Unless you pulled every component from the board and tested it on it's own you can't say they are all good, some of them will not check properly while in circuit.

Put a good board on it and take some voltage measurements, with and without the Guide button pressed, then swap in the bad board and do the same to find out where the issue is. Could be around the Q8/Q9 or Q6/Q7 area.
