PS5 Won't Turn On or No Signal?
Every Cause, In Order
Dead PS5, black screen, TV insisting there's no signal — there are only seven things it can be, and they run from a $0 fix at the wall to a fault buried in the main processor. This guide walks the whole list, cheapest to dearest, so you know exactly where you stand before you spend a dollar.
GTA 6 lands 19 November. If your PS5's been asleep since summer, this is why the screen stays black — see the full countdown →
Listen and look before you touch anything
The lights and sounds a PS5 makes — or doesn't make — split the whole problem in half. Thirty seconds of paying attention tells you which end of this guide you're headed for.
No beep. No light. Nothing.
Press the power button and the console does absolutely nothing — no beep, no flash, no fan. Power isn't reaching the board, or the power supply can't do anything with it. Your fault is in causes 1, 3 or 4 below. Start at the wall, because it's free.
Beep, blue flash, then dead
It beeps, the light blinks blue for a moment, then everything cuts out. The console is trying to boot and the power supply is collapsing under load — or, more rarely, something on the board is shorting. That's cause 4. The motherboard itself is usually fine.
White light, black screen
Beep, solid white light, controller connects — but the TV sits on "no signal". The console is actually running. The picture is going missing on its way to the TV, which puts you in causes 2, 5 and 6: cable, HDMI port or retimer. Skip straight there.
Seven causes, cheapest to dearest
Work through them in order. The first three cost nothing and clear a surprising number of "dead" consoles. From number four on, the fault is inside the case and it becomes bench work.
1. The power point and the figure-8 cable — $0, do it yourself
Boring, and it catches people out weekly. Plug a lamp or phone charger into the same power point and confirm the point actually works — power boards and wall switches fail, and half-pressed switches behind TV units are a classic. Then pull the figure-8 power cable out of both ends, check the console-end socket for bent metal, and push it firmly back home. Better still, borrow the identical cable from a TV, monitor or PS4 and try that. A cooked cable looks exactly like a cooked console until you swap it. If the console now beeps, you're done and it cost you nothing.
2. The HDMI cable and the TV input — $0, do it yourself
This one's for the black-screen crowd: console beeps and lights up, TV says no signal. Before blaming the PS5, swap in a known-working HDMI cable from another device — cheap cables die quietly and take the picture with them. Flick through every input on the TV, because "HDMI 2 not HDMI 1" has ended a lot of panic. Then try a different TV or monitor entirely. If another screen gets a picture, your TV's HDMI input is the patient, not the PlayStation. Two minutes, zero dollars, and it rules out everything outside the console.
3. A rest mode glitch — $0, do it yourself
Rest mode is the PS5's known soft spot. A power flicker or a bad firmware moment while the console dozes can leave it wedged in a state where the power button seems to do nothing, or it "turns on" with a black screen. The fix: pull the power cable out and leave it out for two full minutes so the board fully drains. Plug back in, then hold the power button down and keep holding through the first beep until you hear a second beep about seven seconds later — that's safe mode. Plug a controller in via USB cable. If the safe mode menu appears, pick "Change Video Output" for a no-signal fault, or just restart the console. No safe mode screen on a known-good cable and TV? The fault is hardware, and it's inside the box.
4. The power supply — $350, bench repair
The most common hardware reason a PS5 won't turn on. The PSU is a sealed unit bolted inside the console, and when it fails you get the classic signatures: totally inert, or the beep-blue-flash-dead pattern where it starts to boot and collapses the moment real load hits. Sometimes it's one blown component inside the supply, sometimes the whole unit needs replacing — either way it's $350 fixed, parts, labour and GST included, and your motherboard, storage and saves are untouched. This is not a DIY job: the PSU holds charge after it's unplugged, and there's nothing user-serviceable inside it. Full detail on the no-power fault family is in our PS5 won't turn on repair page.
5. The HDMI port — $340, board-level repair
The number one PS5 fault in the country, full stop. The port is nineteen fine pins soldered directly to the motherboard, and it cops every knock, cable yank and forced plug the console ever experiences. Cracked solder joints or bent pins mean the console runs perfectly — beep, white light, controller connected — while the TV sees nothing, or a picture that cuts in and out when the cable moves. Shine a torch into the port: bent or blackened pins confirm it. Replacement is microscope work with hot air, done on our bench daily at $340 fixed. Everything about the fault, the repair and what to expect is in the PS5 HDMI repair guide. And if the light is solid white with a black screen, read the white light of death explainer — same fault family, scarier name.
6. The retimer IC — covered under the $340, board-level repair
Directly behind the HDMI port sits a small chip called the retimer. Its job is to clean up and re-time the video signal before it leaves the console, and when it dies the symptoms are identical to a broken port — black screen, no signal, console otherwise happy. Here's the trap: the port can look flawless under a torch and even under a microscope while the retimer behind it is stone dead. It's why cheap port-swap outfits hand back "repaired" consoles that still show nothing. We test the port, the retimer and the traces between them as one diagnosis, and both are covered under the same $340 price — you're never charged twice for one fault.
7. The APU — rare, diagnosis first, honest answer guaranteed
The dearest word in console repair. The APU is the main processor — CPU and graphics on one chip — and when it genuinely fails, the console may power up with no video, refuse to boot, or shut down seconds in. Genuine APU death is rare, and it's over-diagnosed everywhere: plenty of consoles written off as "dead APU" land on our bench and turn out to be a $350 PSU or a $340 HDMI-path fault. Related and more common: consoles that overheat until they kill themselves mid-game because the factory liquid metal has pumped away from the chip — caught early, that's a $160 clean and fresh liquid metal application, not a dead processor. If diagnosis does confirm the APU, we'll say so plainly, quote honestly, and offer a trade-in if fixing it isn't worth your money.
DIY-safe vs board-level: where the line is
Everything in causes 1 to 3 is fair game at home — swapping cables, changing inputs, power cycling and safe mode can't hurt anything, and you should do the lot before booking a repair. We'd rather you find a dud cable than pay us to find it.
The line is the outer shell. Causes 4 to 7 all live inside the console: the PSU stores charge after unplugging, the HDMI port and retimer need hot air, flux, a microscope and a steady hand, and the APU sits under Sony's liquid metal — open the console carelessly and that liquid metal can migrate onto the board and short it. The saddest jobs on our bench are YouTube-tutorial repairs where a heat gun lifted the board pads, turning a $340 fix into an unrepairable motherboard. If the free checks didn't wake it up, stop there and let the bench take over.

PS5 won't turn on — your questions
Why won't my PS5 turn on at all — no light, no beep, nothing?
A completely inert PS5 means power isn't getting through. Check the power point with another appliance, swap the figure-8 power cable, and hold the power button for 15 seconds with everything unplugged. If it's still dead, the power supply is the most likely fault — a $350 repair or replacement. Fuses and board shorts are the rarer causes, and diagnosis tells us which before you spend anything.
My PS5 turns on but the screen is black and the TV says no signal — what's wrong?
If the console beeps, the light comes on and your controller connects, the PS5 is running — the video is going missing between the console and the TV. Swap the HDMI cable and try another TV input first. If it's still black, the fault is the HDMI port or the retimer chip behind it on the motherboard. We test both under one diagnosis and quote one fixed price: $340. Full breakdown in the PS5 HDMI repair guide.
Is it the HDMI port or the retimer chip?
You usually can't tell from the outside — a failed retimer produces the same black screen as a cracked port, and the port can look perfect. That's why cheap port-swap repairs sometimes come back still broken. We test the port, the retimer and the traces between them under the microscope, and both are covered under the same $340 fixed price.
Can I fix a PS5 that won't turn on myself?
The free checks, yes: power point, both cables, TV input, a hard power cycle and safe mode. Do all of those before spending a cent. Past that point every remaining cause lives inside the console — power supply, HDMI port, retimer, APU — and needs board-level tools. DIY heat-gun attempts regularly lift pads and turn a $340 repair into an unrepairable board.
How much does it cost to fix a PS5 that won't turn on?
Depends on the cause. Power supply repair or replacement is $350. HDMI port repair, retimer included, is $340. A full internal clean with fresh liquid metal — the fix for overheating shutdowns — is $160. Diagnosis confirms the fault first and you get one fixed quote before any work starts. $0 upfront, 3-month workmanship warranty.
What if it's the APU? Is the console dead?
A failed APU is the rarest and dearest cause on the list, and it's the one we diagnose most carefully — plenty of consoles written off as "dead APU" turn out to be a PSU or HDMI fault. If it genuinely is the APU we'll tell you straight, quote honestly, and offer a trade-in if the repair isn't worth your money. You decide with the facts in front of you.
