Direct answer to the question

• Most probable fault on a DS4 JDM‑055 with “charging yellow OK, BT light blinks, can’t pair, only PS button works; sticks and other buttons dead” is a broken/loose key‑matrix and/or main flex (FPC) connection, or loss of the 3.3 V input rail to the analog/button circuits. Less commonly, the main board (MCU/ADC domain) is damaged.
• Try a hard reset and USB pairing with a known‑good data cable first. If unchanged, open the pad and reseat/replace the two critical ribbons: the main USB/lightbar FPC and the button membrane FPC. Measure 3.3 V at the stick modules. If rails and ribbons are good but inputs still don’t scan, the main board is likely faulty and replacement is the practical fix.

Detailed problem analysis

• Symptom mapping:

  • Yellow charge LED = battery and charge path alive, 5 V input OK.
  • BT flash but no pairing = controller powers and the MCU boots, but input scanning and/or USB data path may be down; PS button still working means its dedicated tactile switch on the PCB is being read, while the shared key matrix and ADC inputs are not.
  • “All buttons and sticks dead except PS” strongly points to: 1) The conductive film (key‑matrix FPC) not latched or its traces cracked, so no buttons/D‑pad/Options/Share are seen. 2) Loss of the 3.3 V “IO/ANALOG” rail feeding the potentiometers and button pull‑ups, which makes both sticks and all matrix inputs appear dead simultaneously. 3) Main FPC (USB/lightbar board to main board) not seated or damaged; on JDM‑055 it carries USB D+/D− and some reference/ground continuity for subassemblies. If it’s open, USB pairing fails and, depending on the failure, inputs can behave erratically. 4) Less often: ADC/input front‑end or the MCU’s GPIO bank damaged by ESD/liquid.

• Why it won’t pair:

  • If the controller can’t present any valid inputs after wake, PS4/PC pairing (USB/Bluetooth) may not complete or you appear “connected but unresponsive.” A charge‑only cable also prevents USB pairing entirely.

Current information and trends

• Aftermarket parts (JDM‑055 button conductive films and main FPC ribbons) are inexpensive and widely available; quality varies, and low‑cost films frequently arrive with weak carbon pads or skewed stiffeners. Prefer OEM pulls or higher‑grade aftermarket with thicker copper and crisp ZIF tails.
• Fast‑charge phone adapters (QC/PD) and worn micro‑USB plugs remain a common cause of port stress; stick with 5 V USB ports or the console’s ports for charging/testing.

Supporting explanations and details

• Input architecture basics:
  • PS button = discrete tactile switch on the main PCB to a dedicated GPIO.
  • Other buttons/D‑pad = carbon pads on a flexible membrane routed via a ZIF connector to the MCU’s scan matrix.
  • Analog sticks = 10 kΩ potentiometers referenced to ~3.3 V with wipers into ADC inputs.
  • If the 3.3 V rail to inputs is missing/open, both sticks read “dead,” and all matrix lines float (no buttons register), while the PS button can still work.
• Ribbons/connectors:
  • JDM‑055 has at least two key ZIFs to check: the “main” FPC (USB/lightbar board ↔ main board) and the “key‑matrix” FPC (button film ↔ main board). ZIF latches are fragile; an unlatched or cracked tail gives exactly your symptom.

Ethical and legal aspects

• If under any warranty or consumer protection period, avoid opening the controller; self‑repair can void coverage.
• Dispose of e‑waste (bad batteries/boards) via proper recycling channels; avoid landfill.
• Use genuine or reputable third‑party parts; counterfeit batteries and low‑grade flexes can be unsafe.

Practical guidelines

1) External sanity checks (no disassembly)

• Fully power off the PS4. Forget/remove the controller from Bluetooth devices.
• Hard reset the DS4: press the rear pinhole reset for 10 seconds.
• Use a known data‑capable micro‑USB cable. Test on a Windows PC: it should enumerate as “Wireless Controller.” If it only charges (no device shows), the cable or port is charge‑only/faulty.
• Try PS4 Safe Mode USB pairing: with the console off, hold power until the second beep, connect the controller via the tested cable, press PS. If it works in Safe Mode, OS settings were the issue; if still dead, proceed.

2) Open and reseat (ESD care; disconnect battery first)

• Remove back screws, carefully split the shell; unplug the battery immediately.
• Reseat the main USB/lightbar FPC: flip the ZIF latch up, clean the tail with IPA, reinsert squarely to the stop, close the latch.
• Reseat the key‑matrix (button film) FPC the same way. Inspect the tail for cracks/creases and the ZIF for broken latch ears.
• Inspect for liquid/green corrosion, especially around FPC areas and small series resistors near the connectors.

3) Quick electrical checks

• Battery: ~3.7–4.2 V.
• USB VBUS: ~5 V at the port when plugged into a PC/PS4.
• Analog/stick rail: measure between stick Vcc and GND pads; expect ~3.0–3.3 V. If 0 V, trace back to its LDO/fuse/series resistor; if shorted to GND, find and clear corrosion/bridges.
• Button matrix continuity: with the film removed, check continuity of the film’s tail traces; any open = replace film.

4) Parts to try first (cost-effective)

• Replace the button conductive film (JDM‑055 specific).
• Replace the main USB/lightbar FPC ribbon.
• If USB data still doesn’t enumerate with a known data cable, replace the USB daughter board.

5) When to stop and replace the main board

• Rails are correct, ribbons good/new, USB enumerates but all inputs except PS remain dead, or nothing enumerates despite a new daughter board and ribbon: the MCU/ADC domain is likely damaged. Board‑level IC replacement is possible but uneconomical without hot‑air, microscope, and boardview. Replacing the entire JDM‑055 main board (or the controller) is the pragmatic path.

Possible disclaimers or additional notes

• Test‑point labels and exact rail values vary slightly across JDM‑055 sub‑revisions; measure relative to GND and follow the stick Vcc as your reference for input rail health.
• If the ZIF latch plastic is cracked, the cable may appear “in” but won’t make pressure contact; the connector itself must be replaced.

Suggestions for further research

• Look up detailed JDM‑055 teardown photos to identify your exact FPC routing and ZIF latch color/type before ordering parts.
• Search community repair logs for “only PS button works DS4” to see images of common cracked film tails and lifted ZIF latches.
• If equipped, use a USB protocol viewer to confirm HID enumeration and input report activity while pressing buttons.

Brief summary

• Your symptoms match either a disconnected/damaged button film and/or main FPC, or a missing 3.3 V input rail. Do a hard reset and USB pairing with a proven data cable; if unchanged, open the controller, disconnect the battery, reseat/replace the key‑matrix film and main FPC, and verify the stick Vcc ≈3.3 V. If rails and ribbons are good yet inputs remain dead, the main board is faulty—replacement is the sensible fix. If you’d like, I can tailor a step‑by‑step with photos/locations once you share clear pictures of your board and FPC connectors.
