I have changed that component from a donor board and now it works correctly

Same issue with my controller, it does not work when antenna cable is connected
tried to remove all components connected to ground  (close to antenna and usb connector) on bottom board but still it does not work

what did you replaced at the end to make it work again?

Very strange RSY behavior.

When potentiometer soldered I have about 1V at middle pin, but gamepad test shows me min position of RY.

When I move stick and got about 1.7V at middle pin tester show middle position of RY

At max pos of RY I got 1.8V and max position in tester.

Movement in range 1.65-1.8V only. At other range - min position.

13 pin at 1914 SOC BOARD board have the same voltage and resistanse about 0.1Ohm between middle pin of RY.

By sheme this point goes directly to ARM chip.

Is it ARM damaged by this line? Or bad contact and maybe rebolling will help?

No idea on the exact specs, but the FB1 is just a Ferrite Bead, you can jumper wire that one. The C29 is on the SDA line, so it's going to be a low pF value. The 1708 has a 47pF on there.

C66 - 100nF
C2 - 100nF
C53 - 1.0uF

С74, C81 - ?? My tester couldn't set their parameter. If I can find out the nominal value, I'll add it.

C74 and C81 are decoupling caps on the 3.3v rail, values are not critical, anything from 1nF to 100nF would be fine there.

Have you figureout what component need to be replaced ?

If plugging up the antenna cable causes it to short and not power up, the only things I've seen cause that are eihter the RF transformers are bad, some other component in that antenna circuit is bad, or the MCU is bad. I've no way to accurately measure those values, so a donor board is the best place to get replacements, and the only place to get another MCU.

I got a controller from my cousin today and I'm trying to fix it, I've already replaced the part called "A5AE" because it was burnt, but the controller still doesn't work. What else could have been damaged? The controller had this failure after installing freshly charged batteries. I've marked what was burnt in the picture.

U4 has a tendency to fail and is suspect, or any of the traces/components connected to it.

While soldering the analog I removed r16, c26 and c24. Could they be the reason it is always pointing to the upper left corner and not controlling the analog? And what are their values?

The value of R16 is shown in the schematic in the first post. That one missing would only cause the LSC button to stop working.

C24 and C26 missing will not cause that issue either.

I'd suspect there is some trace damage somewhere from the stick not being desoldered properly and then being pried off the board.

Hello
I have a problem, when I connect the joystick, several buttons are pressed simultaneously, I saw something suspicious in this area, can someone tell me the values ​​or if this is where the defect comes from?

That's a common spot for corrosion to happen on the 1708 and 1914 boards. R4 ad R7 are both 0 ohm jumpers, then C37 is 4.7nF. All of those can still be fine and the traces or a via there can have corrosion and cause issues. U4 on the other side of the board can also go screwy and cause that issue, but it looks like R4 there has probably gone open from corrosion on yours there.

I have another problem, I changed the left stick, recalibrated, everything is fine. After 10 minutes it started to pull down, when I push it down it goes up....do you have any idea why? I have two boards that do the same thing and with different models of special xbox sticks
