Chosen Solution

My ps4 DS4 is doing as title say’s but only does this if u connect usb too it otherwise does nothing. Works in safe mode with usb connected tho, Nothing in normal mode. Tried connecting it too pc with usb makes connection sound on the pc and lightbar on DS4 blinks once then off. Then tried too connect DS4 by Bluetooth too pc WIRELESS CONTROLLER appears in list with ready too pair underneath and pair button too push on screen. So try too put DS4 into pair mode where the lightbar blinks white (holding SHARE & PS BUTTON down) nothing happens so can’t pair. Tried also resetting DS4 with thin object connected with usb will flash lightbar once does nothing if push reset without usb connected. Think that’s everything I’ve tried just going too try connecting too my Android now, So PLEASE PLEASE somebody help me don’t know what else I can do other than open it up and trying a few things………..

solved!! So. This happened to me.. my controller would flash yellow once then not respond again unless plugged in or reset. Then once again one flash then nothing… It ended up being a faulty conductive film that stopped working properly. Here is how you can easily find and fix this problem.. Solved this by looking at forums and adding different solutions together. First off plug the controller into a PC. Once it has installed go into control panel -> hardware and sound -> printers and devices -> RIGHT click ‘wireless controller’ -> select ‘Game controller settings’. -> select ‘Properties’ -> make sure your in the ‘TEST’ tab up the top. From there TEST ALL YOUR BUTTONS. I found my PS button (that turns the controller on) was faulty!!! It did not show up as to it working when pressing that button but all other buttons worked… So I went into ebay and bought the ‘conductive film for ps4 buttons controller’ .. for $3 Waited in post took apart my controller changed films and bingo!! Works perfectly fine. If any other buttons are faulty it will show up on that test page. MAKE SURE YOUR USING THE RIGHT CABLE. Some cables don’t transfer properly. So just keep changing cables if the pc is not picking up the controller (or change USB ports). Hope this helps as it took a while to find all this. Good luck!

Have you reinstalled the drivers?

I fixed this issue by going into device manager, finding the controller there, properties>update driver>manually choose> and then choosing Xinput supported HID controller driver or something like that from the driver list.

Try this, friend. https://youtu.be/GBpqfhPPJPw

Mine was doing the same and I just plugged the charger in and when it blinked I pressed the ps button twice. Not gonna lie I did it on accident.

It’s more than likely a simple router cache issue, try this before all the other trouble shooting, too easy: Turn off your PS4™ and unplug it from the power source. Unplug your router or modem from the power source. Sometimes connecting issues are caused by internet router WIFI signals, unplugging it will help troubleshoot the connection issue. Locate the small reset button on the back of the DUALSHOCK®,  located near the L2 button.Use a small, unfolded paper clip or something similar to push the button inside the tiny hole. Hold the button down for roughly 3-5 seconds and release.Then, re-connect your DUALSHOCK®4 (micro USB port located on the back) to your PS4™ (USB port located on the front), using the USB cable that came with your PS4™.Plug your PS4™ into a power source. Don’t plug your internet router in at this time. Press the PS button on DUALSHOCK®4 controller and then log into your profile. If you don’t already have a user profile created, find the instructions at: “Creating and Deleting User Profiles” on PS4 (type that in at Sony website support page search)Plug your router back in - done!
