DualSense

Power

Problem	Solution
PS5 controller does not charge	If the PS5 controller does not charge, check the capacitors around the DA9087 chip, if they are short-circuited replace the DA9087 power management chip. Credit goes to My Mate VINCE, here is video of his finding https://www.youtube.com/watch?v=OKs5DsDVNI8
Controller doesn't turn on when powered from USB	Check the battery, Dualsense requires the battery to be connected and functional to work over USB
Controller only charges with USB-C to USB-A cables and does not work as a data input following Type-C port replacement	See the Compatible Parts section.

Inputs

Problem	Solution
Controller analog drift (move by itself in-game)	There are four pots, two for each analogue stick. They should be cleaned first and if they are used up, then replaced, the whole analogue stick with the mechanism can be changed or only the pot. There are two types of sticks used, green pot ALPS, and orange pot. You can only swap green to green and orange to orange due to shaft size. See Fig 1. These pots will likely not center properly after replacement, you have to rotate them before soldering them in the correct center position, on PCBs without plated through holes you can bend over the pins to make this easier. In extreme cases you will need to shave the corner locating pegs.
Controller does some things alone (in the game it enters the inventory itself or the character jumps)	clean the contacts on the board and foil and add some material like foam under the foil. See Fig 3, 4, & 5.
R2/L2 doesn't return to 0 or feels weird/crunchy	Broken spring, common problem of early revision. You can replace this spring, you can also use the DualShock 4 spring.

Compatible Parts

Problem	Solution
USB-C Port	JAE Electronics DX07S016JA1R1500 Buy on Digi-Key Buy on Mouser USB-C Connector on a BDM-020 controller. Be sure that you are buying a compatible replacement port. There are many replacement ports available for sale that are the same size/footprint as this port, but they have a different pinout and will not work properly. See the manufacturer's pinout on page 2 here

Diode Mode Readings

Use these diode mode maps as a guide to troubleshoot a problem. You must use the RED PROBE on ground and the BLACK PROBE on the pin you are measuring.

For example: You are troubleshooting a situation where USB-C to USB-C cables do not charge your controller, so you probe the pins on the USB-C connector that correspond to the CC lines. If a pin says you should read 1.4375 and you are reading OL or a short to GND then that's where you need to go.

If instead of getting 1.4375 you read 1.4216, move on to the next one. Remember, every multimeter is different and even slight differences in temperature affect these readings. What you are looking for is extreme differences in values; if you are expecting some value and you get a short to ground, that is where it is more likely to be your issue.
