FAQ
TL;DR: DualShock 4 V2 uses 2 different charging ICs; “The charging circuits in the above boards are not interchangeable.” This FAQ helps DIYers fix PS4 JDM‑050/055 no‑charge issues by targeting PMIC, USB fuse, and ribbon faults. [Elektroda, marek666, post #21233887]
Why it matters: It guides owners on how to fix a DualShock 4 that won’t charge or power on, and when repair isn’t worth it.
Quick Facts
- JDM‑050 uses TC7736FTG; JDM‑055 uses S2PG001A—these charging ICs are not cross‑compatible. [Elektroda, marek666, post #21233887]
- Replacing S2PG001A often restores function; it’s a custom SONY PMIC and not cheap. [Elektroda, lysy1980, post #18941464]
- An SMD fuse sits on the USB daughterboard and can blow, blocking charge/data. [Elektroda, lysy1980, post #18941464]
- External “fast” chargers commonly kill V2 pads; charge via the console’s USB. [Elektroda, lysy1980, post #18941464]
- A loose USB‑board ribbon can mimic a dead pad; reseat or replace it. [Elektroda, Pajda89, post #21317333]
Why won’t my DualShock 4 JDM‑055 charge or power on?
Usual culprits are the S2PG001A PMIC, the SMD fuse on the USB board, or even the ARM MCU. If a known‑good, charged battery gives no response, suspect the PMIC or MCU. External chargers frequently precede these failures. Weigh repair time and cost against a used replacement. [Elektroda, lysy1980, post #18941464]
Can I swap the charging ICs between JDM‑050 and JDM‑055 boards?
No. JDM‑050 uses TC7736FTG and JDM‑055 uses S2PG001A. “The charging circuits in the above boards are not interchangeable.” This also makes cross‑board repairs uneconomical if the IC is bad. [Elektroda, marek666, post #21233887]
Is replacing S2PG001A worth it?
Replacement often fixes no‑charge faults, but S2PG001A is a custom SONY PMIC and costs more than typical regulators. Consider parts price, microsoldering skill, and the chance the ARM is also bad. Buying a used pad can be cheaper overall. [Elektroda, lysy1980, post #18941464]
How do I check the USB daughterboard fuse?
Do this quick 3‑step check:
- Disconnect the battery and open the pad; unplug the USB board ribbon.
- Locate the small SMD fuse on the USB daughterboard near the port.
- Measure continuity/ohms across it; open reading means replace the fuse/board. [Elektroda, lysy1980, post #18941464]
I get three orange flashes, then nothing. What should I probe?
Three orange blinks point to a charge/power rail issue. The black parts pictured near that area are resistors, and they should read short. “That’s how they should be shorted and I think they are resistors.” Check them for near‑zero ohms; a lone one showing value can be normal. [Elektroda, SebastianPaska, post #19902289]
How do I check for shorted SMD capacitors on the board?
Use a multimeter in diode or continuity mode with the battery disconnected. Probe both sides of each SMD capacitor around the PMIC and USB rail. A persistent beep or near‑zero reading to ground suggests a short that needs isolation. [Elektroda, szalony1, post #18032229]
Does a charged battery prove the charging circuit is fine?
No. If the pad still shows no life with a charged battery, the PMIC or even the ARM MCU may be faulty. In that case, battery condition is irrelevant until the power‑management path is restored. [Elektroda, lysy1980, post #18941464]
I used a fast charger and the controller died—what likely failed?
External chargers often kill V2 pads by damaging the PMIC or related power paths. “Usually the PAD kills charging from an external charger.” Inspect the USB fuse and plan for a PMIC replacement if the fuse is intact. [Elektroda, lysy1980, post #18941464]
Can I solder the charging system between JDM‑050 and JDM‑055 boards?
No. JDM‑050 uses TC7736FTG and JDM‑055 uses S2PG001A, and they are not interchangeable. Attempting that swap is impractical and uneconomical for a DIY repair. [Elektroda, marek666, post #21233887]
What exactly is the S2PG001A on JDM‑055?
“S2PG001A is a custom PMIC made for SONY with integrated audio.” It manages charging and key power rails. Failure often causes no‑charge and no‑power symptoms. Replacement typically restores function if the MCU is intact. [Elektroda, lysy1980, post #18941464]
What charging IC does JDM‑050 use?
JDM‑050 uses the TC7736FTG charging/controller IC. It differs from the S2PG001A used on JDM‑055, and they do not swap. This affects repair paths and donor‑board choices. [Elektroda, marek666, post #21233887]
Are schematics or part values (e.g., near TC7736FTG) available?
A member reported no diagram or schematic when seeking nearby resistor/capacitor values. Without public schematics, identify values by comparing to a donor board or measuring in‑circuit. [Elektroda, mstrxxxgames, post #21474708]
Could a loose USB ribbon be the whole problem?
Yes. Drops can dislodge the ribbon between the mainboard and the USB daughterboard. Reseat both ends or replace the ribbon/USB board, as this can fully restore charging. [Elektroda, Pajda89, post #21317333]
When is it smarter to buy a used pad instead of repairing?
If the PMIC is bad and parts are costly, or if the ARM is suspect, replacement becomes uneconomical. Both JDM‑050 and JDM‑055 charging ICs are expensive, making many board‑level repairs not cost‑effective. [Elektroda, marek666, post #21233887]
