Why is my PS4 controller not charging/getting warm while plugged in?

Both of my PS4 controllers started doing this on the same day. The LED lights up intermittently, but shuts off shortly after plugging it in unlike what it used to do while charging. I changed the batteries in both of the controllers and they worked until the batteries needed charging, then I was back to where I started. Another thing is when I push the PS button on the controller when it shows the battery status on the screen it shows up as a question mark. I have also tried changing out the charging port circuit card and ribbon cable, but then the LED would only blink red one time and then I would get nothing. The controller works if it remains plugged into a power source, but it starts to get warm after a while. Any help would be appreciated. I want to make sure that whatever caused this does not happen again if I get a new controller. I find it strange that it happened to both controllers on the same day. Thank you.
