Hi, does anyone know what IC is responsible for managing the analogue sticks inputs?
I have a Vita I bought a couple years ago with “drift” on the right stick so I replaced it and still the same.
If I swap the left and right, still the same
If I disconnect it, the left one plays up
If I disconnect both it still drifts
It has had a bit of water damage that I cleared up around the rear facing camera but not fixed the issue
Neither camera works even though I have replaced them both with new
This is not the usual issue I find on the internet so haven’t touched it in a while as can’t find anything else with similar issue so thought I would post here and see if anyone else may have an idea where to start with it
I reflowed the below 2 ic’s and cleaned up the camera connector again as that was where the liquid damage was and got both cameras working now but the drift is still there
STMicroelectronics [3GA51H] gyroscope - PURPLE
Kionix [KXTC9] three-axis MEMS accelerometer - BLACK
Any ideas on where else to look for something that may be causing this issue?
@Justen602 yes as much as I can. also tried replacing the button board and that didn’t work. Checked for shorts, checked as many caps as I could for diode readings to make sure there are connections etc. Removed all the metal covers and gave it a bath in IPA for about 20 minutes while brushing it and flipping it several times and still no change.
It is a really strange issue but one that stops me from being able to play any games that require the right thumbstick. It’s even weirder that without either stick connected I still get issues and without that one connected, the left one starts acting up.
Only thing I can think of is there is an issue with the IC that deals with the signals from the sticks or the components surrounding it but I don’t know which IC deals with the thumbstick inputs.
From the sounds of it i would replace the three-axis mems. It deals with the left-right, up-down, in-out motions. Might have good traces and good connection but the IC might be fried. I am not really having any luck finding them online, best bet would be buy a doner board.
