Hark Tech offers UK mail-in power-fault repair for PlayStation and Xbox consoles that won’t turn on, click on then die, beep-of-death or show a brief LED then nothing. We diagnose with multimeter and oscilloscope, swap failed PSUs and rebuild blown power rails at component level. Typical cost £55–£130, free diagnosis, no-fix-no-fee, 90-day warranty, 3–7 working day turnaround.
UK mail-in power-fault repair for PlayStation and Xbox consoles. Symptoms include no LED at all, a brief light that immediately dies, the “beep of death” (PS4), the “blue light of death” (PS4), or a console that clicks on then shuts back off. We diagnose at the PSU output and through every voltage rail, then repair at PSU or board level — capacitor recap, MOSFET swap, power-IC replacement, fuse and inductor work. Typical cost £55–£130, free diagnosis, 90-day warranty. 3–7 working day turnaround from arrival.

Press the power button, nothing — no light, no fan spin, no sound. Either the standby rail is dead (often a blown fuse or PSU) or there’s an upstream short pulling the whole rail down.
LED comes on for a fraction of a second, then dies. The protection circuit is detecting a fault on one of the rails as soon as the relay closes, and shutting things down to prevent damage. Very fixable.
One quick beep, brief blue light, then power-off. Almost always a power-supply fault on the PS4 itself. PSU swap is the most common fix; sometimes it’s a downstream short.
Pulsing blue indicator that never goes white — the console is failing to negotiate HDMI or hand-off to the SoC. We see HDMI handshake faults, board-level shorts, and (rarely) APU failure. Diagnosis distinguishes them.
Touch sensor responds, you hear a faint click from the relay, and then nothing. The PSU initialised but a downstream rail tripped protection. Usually a single bad component on the motherboard.
Console powers up, fan spins for 2–5 seconds, then immediately shuts down with no error. Usually one of the secondary voltage rails (1.05V, 1.8V, 3.3V) collapsing under load. Component-level repair fixes it.
Power-fault repair pricing depends on whether the failure is in the PSU (cheaper) or in the motherboard’s power circuitry (more involved):

That’s the relay or power IC firing up briefly, then the protection circuit detecting a fault and shutting it back down. On PS4 it’s known as the “beep of death”; on Xbox it’s a brief LED + click. The cause is almost always either the PSU itself failing or a short on the motherboard pulling one of the rails low.
We start at the wall — confirm the cable and outlet, then measure the PSU’s main output with a multimeter (12V on most consoles). If that’s good, we move to the standby rail, then through every voltage rail on the motherboard in turn. A blown MOSFET or shorted ceramic capacitor will show as a rail pulled to ground; we trace it back to the failed component using thermal imaging and current injection. The full diagnosis is free.
Roughly 50/50 in our workshop. PSUs fail outright more often than people expect — bulged capacitors, dried thermal pads, blown primary-side MOSFETs. The other half are board-level: a power IC that’s failed, a single shorted capacitor pulling 1.05V to ground, or (rarely) a damaged trace. PSU swaps are quicker and cheaper; board-level work takes longer but is still very repairable.
PSU replacement is typically £55–£90 depending on the console. Board-level power-rail repair (capacitor recap, MOSFET or power-IC swap) is typically £90–£130. We give a firm written quote after free diagnosis — no chargeable work happens without your approval.
Almost always yes. Power-fault repair doesn’t touch the SSD or hard drive — your saves, games and account data stay intact. The rare exception is when a PSU failure pushed an over-voltage onto the storage controller; we test for this during diagnosis and warn you up-front if it’s a concern.
If the console boots, runs for 20–60 minutes and then dies, that’s thermal, not power. We’d handle that under our overheating repair (cheaper, different scope). If you’re not sure which it is, send it in and the free diagnosis tells you.
