Capacitive Buttons on Playstation 4
« on: August 21, 2015, 23:10:06 PM »
Hi Everyone. First of all, forgine any english mistakes that I may do here.

I have a Playstation 4 and it keeps ejecting the disc all the time. I tried everything I could and the problem persists. Warranty is not an option since I bought the system in the USA and I live in Brazil. The button that ejects the disc is capacitive. Does anyone knows how it works? And how does the amount of charges builds up randomly? The button is not touched and it keeps beeping as if it was someone or something touching it. How can I keep the button with no charges or with the less charges I can?

Can anyone help me?
Thanks in advance.

Hello to Brazil  ;)

First, take a look here:

You will find out that the capacitive buttons need good grounding layer. Maybe the touch sensor is not fixed well. Maybe the charging capacitor is not soldered well, or you just need to replace it. Or maybe you can solve the problem by covering the back side of the button with a piece of aluminum foil grounded somewhere to 0V.

It seems it's not a capacitive button problem. Have you tried using different discs? Also, please try to see if there is any dirt or some obstacle near to that button is coming up.
I may also recommend to clean the PS4 reading laser with cleaning disc.
