PS5 not turning on but beeps once, no fan? On this CFI-1100 (EDM-020) a shorted C7112 blew the F7001 5A fuse. Board-level fix with real measurements. ![F7001 on side A of the EDM-020 – the 5 A fuse that blew](https://forum.nopowerfix.com/uploads/default/original/1X/6349a8ee5b5a7b66f2dd293e3efc04a2771b9ed7.jpeg) **Device / model:** PlayStation 5, CFI-1100 series **Board number:** EDM-020 **Symptom:** press power → **one beep** , no fan, no LED, nothing on HDMI **History:** first find was capacitor **C7112** (input cap of IC7101, the 1.8V\_SOC\_VDDA regulator) dead short to ground. C7112 removed, short gone — **but the console still did the single beep.** * * * ### Measurements - Bench 12 V into the PSU connector **CN7001** : **46–48 mA for 15–20 s, then 2 mA** steady. Power button → beep, current never rises. - Subsystem PMIC **IC7002 (DA9065)**: comes up normally on button press — all its outputs present (1.15 V, 1.8 V, 3.3 V SS rails), reset released. So the southbridge side wakes up fine. - **IC7107** (TPS53219, makes 5V\_MAIN): VDD = 12 V, but **EN = 0 V** — the main power-on signal `PSW_MDCDC` is never asserted. - `/AC_IN_DET` = **3.24 V** (correct: 12 V × 10k / 37k). The board knows main power is present. ### The trap (where the hours went) Everything above points at “the controller refuses to turn on main power” — firmware, flash, RTC battery, the EN circuit. All of those were checked and **all were healthy** : - IC7107 forced on through its EN pin → it runs perfectly, **5V\_MAIN = 5.31 V**. Still single beep. - SPI flash IC5001 dumped — structure intact. (Don’t flash a “reference” dump from the internet — revisions differ.) - CR2032 removed and board discharged — no change. Two things fooled the measurements: 1. **L7113 is not on 5V\_MAIN.** Reading open-circuit between JL7102 (5V\_MAIN) and L7113 is _normal_ — they are different rails, not a broken trace. 2. **L7113 and L7102 are not-fitted footprints** (pads bridged with copper on the board). Only L7104 is a real inductor here. ### Root cause The C7112 short didn’t only kill C7112. It sat on **5V\_ACPI\_SOC** , which is fed from 5V\_EVER **through fuse F7001 (5 A, 24 V, FMC10502WH)** — and the fault current **blew F7001**. ```auto 5V_EVER ──┬── F7001 5A ──► 5V_ACPI_SOC ──► SoC standby (S5) rails: │ 3.3V_VRM, 1.8V_SOC_V18_S5, 3.3V_SOC_V33_S5 ├── F7003 5A ──► 5V_ACPI_SSB ──► IC7002 (intact - why the SS rails were fine) ├── F7002 5A ──► 5V_ACPI_WIFI └── F7502 5A ──► 5V_ACPI_FC ``` ![F7001 between 5V_EVER and 5V_ACPI_SOC (schematic)](https://forum.nopowerfix.com/uploads/default/original/1X/bddf5d6d9f85a8854ffeff038599bef3bdf7f3e1.png) ![C7112 on the input of IC7101, fed from 5V_ACPI_SOC (schematic)](https://forum.nopowerfix.com/uploads/default/original/1X/a73253a6d7254d357c629f743f09fc0fe7e446d2.png) **Where they are:** F7001 is on **side A**. C7112 is on **side B** , right beside IC7101. So the short and the blown fuse are on opposite sides of the board. ![F7001 close-up: the fuse, with the two empty bypass positions R7033/R7034 right next to it](https://forum.nopowerfix.com/uploads/default/original/1X/cf05607315a4ea0eb039cdca818cebd894177840.jpeg) ![C7112 on side B, beside IC7101](https://forum.nopowerfix.com/uploads/default/original/1X/a43e1f8d4580ee5951415547f4d2d4a0a668689c.png) With F7001 open, the **SoC standby rails are all dead**. The controller wakes, brings up its own rails through the intact F7003, finds the SoC standby domain missing, beeps once and refuses to assert `PSW_MDCDC`. Correct behaviour — the board was protecting itself. ### Fix 1. Confirm: **CL7113 (3.3V\_VRM), CL7114 (1.8V\_SOC\_V18\_S5), CL7115 (3.3V\_SOC\_V33\_S5) all 0 V** → F7001 open. 2. Before fitting the new fuse: check **5V\_ACPI\_SOC to ground is no longer shorted** (otherwise the new fuse blows instantly). 3. Replace **F7001** with the same rating: 5 A / 24 V. Sony’s parts list allows **FMC10502WH** , **Littelfuse 0435005** or **Panasonic ERB-RD5R00X** , so any of the three in the same size will do. 4. Undo any diagnostic jumpers (e.g. forced EN on IC7107) so the power sequencer works normally. ### The other fuses worth a quick check F7001 has three brothers on **5V\_EVER** , all 5 A. A short on any of their rails can take the fuse out the same way. Check them power-off with the meter across each fuse: a good fuse reads close to 0 Ω, and an open one is blown. The orange silkscreen label marks each one. ![F7002, F7003 and F7502: the other 5 A fuses on 5V_EVER](https://forum.nopowerfix.com/uploads/default/original/1X/666c29886c64b210776ed77bd62eaf8bd46ce40a.jpeg) Close by are the fuses on the main rails, which only matter once the console powers on: **F3501** (2.5 A, 12V\_MAIN), **F3502** (2.5 A, 5V\_MAIN → USB-C) and **F7501** (5 A, 12V\_MAIN → M.2 power). ![F3501, F3502 and F7501](https://forum.nopowerfix.com/uploads/default/original/1X/3c3ce8db89ff2e79b9b0d70a52a9930d853a802b.jpeg) ### Lesson **PS5 single beep + no fan + current dropping to ~2 mA after a C7112 (or any 5V\_ACPI\_SOC) short → measure F7001 first.** A shorted cap on a fused rail usually takes the fuse with it — check the fuse before chasing regulators, firmware or the controller. _Was this your fault too?
