You press the button, the PS5 chimes, the fan spins up, and the TV sits on “No signal”. The disc tray will take and eject a disc. The console is clearly alive. The screen is simply refusing to show anything, and after swapping the cable twice and switching HDMI inputs you are no closer to a fix.
This is one of the most common console jobs we see from Edinburgh City Centre flats, and the cause is usually not the one people expect. This guide walks through what the symptom actually means, the quick checks worth doing before anything comes apart, and when a console repair in Edinburgh is the honest next step.
What “No Picture” Really Tells You
A PS5 that chimes, spins its fan, and does not fall into a safety loop (one slow beep then shutdown) has already passed its first self-checks. The processor, memory, storage and operating system have booted far enough to be waiting on a display. The video signal is being generated somewhere inside the console; it is failing to leave the HDMI port, failing to travel through the cable, or arriving at a TV that is not listening on the right input.
That is useful because it rules out a long list of scarier causes. Dead power supplies, blown fuses on the main board, failed storage and corrupted system software all give very different symptoms. “Everything but the picture” is almost always one of five things, and the five sit on a short bench checklist.
Quick Checks to Try at Home First
Before anything comes to us, these are worth ten minutes on the sofa. More than half the PS5s that arrive in our workshop in St James Quarter area shopping bags turn out to need one of these rather than a repair.
- Swap the HDMI cable, properly. Not the same cable moved to another port, and not a cable rescued from the back of a drawer. PS5 output needs HDMI 2.1 for 4K at high refresh rates; a tired 1.4 cable from an old set-top box can hold a signal at 1080p and drop it entirely at anything higher. Known-good cable, firm click at both ends.
- Try a different HDMI input on the TV. Only one input per TV is typically full-bandwidth HDMI 2.1 — often labelled with a small “eARC” or “4K@120” marker next to the port. The others will fall back to lower-rate signals, and the console may refuse to pick a mode a port cannot carry.
- Boot into Safe Mode. Hold the power button until the second beep (about seven seconds), then plug the controller in by USB and press PS. In Safe Mode choose “Change Video Output”, then “Change Resolution”. The console reboots at 480p, which almost every TV and every cable can carry. If a picture appears, the hardware is fine and the stored video mode was the problem.
- Try a second TV or monitor. A loose or failing input on the TV side causes exactly the same symptom. If the PS5 shows a picture on a second screen, the console is not the fault.
- Power-cycle properly. Hold the power button until it fully shuts down, then unplug from the wall for a full minute. The HDMI handshake with the TV is renegotiated from cold on the next boot.
Work through those in order. If any one of them brings the picture back, the console does not need opening.
Why City Centre Flats See This More Often
The reason the HDMI story matters in the city centre specifically is physical space. A PS5 is a big piece of plastic, and in the two-bedroom tenement flats around the Grassmarket, Old Town, New Town and the Southside, it rarely gets a run of empty shelf behind the TV. More often it is wedged between the back of a flat-screen and a plasterboard wall, with the HDMI cable bent through 90 degrees to clear the gap.
Over a year or two of being nudged, moved for cleaning and plugged into controllers, that bend works the HDMI connector loose on the board. The port is through-hole soldered on a daughter card inside the PS5, and the leverage of a stiff cable in a tight space is more than enough to crack a solder joint without ever damaging the socket visibly. We see the same pattern on consoles that have been moved for a flat-share handover or an Airbnb turnaround; a lot of plugging and unplugging, no change in use.
A real example from the bench this quarter: a PS5 came in from a tenement flat off the Royal Mile with the exact symptom described above. The HDMI cable was a known-good 2.1 and worked straight away on a second console, so we knew the fault was on the PS5 side. Under magnification, one leg of the HDMI socket was pulled away from its pad by less than a millimetre, enough that the handshake was failing most of the time and succeeding briefly when the console was warm. Lifted the port, cleaned the pad, reflowed and reseated it, and it has been fine since.
What Is Usually Broken Inside
When the home checks have been exhausted, there are three failure modes we see repeatedly on PS5s brought in for “no picture”:
- Lifted HDMI port. The port looks correct from the outside, but one or more of its surface-mount or through-hole pins has lost contact with its pad. Needs a careful lift, a clean of the pads, and a reflow or a full port replacement. This is microsoldering work rather than a straight board-swap; the chip around the port stays, only the connector moves.
- Damaged HDMI retimer or filter components. Behind the port on the PS5 there is a small cluster of filter resistors and capacitors, with the HDMI retimer chip nearby. A bent cable can jolt one of those parts loose on impact; a surge from a cheap non-standard HDMI switch can take out the retimer itself. Both are repairable, but only one is cheap.
- Firmware stuck at an unsupported mode. Rare, but worth mentioning: a PS5 that was last used on a 4K/120 OLED and then plugged into a parent’s older 1080p set occasionally refuses to downshift. Safe Mode option 2 fixes it. If Safe Mode will not display either, the hardware is in play.
What We Do on the Bench
When a PS5 arrives with this symptom, the bench routine is deliberately boring. We confirm the console boots to the point of generating a video signal (a blind controller sync in Safe Mode usually proves it). We swap in a known-good cable and TV before touching a screwdriver. We check for mechanical damage to the port under magnification. If a reflow is needed, the console is stripped down to the main board, the port is lifted on a hot-air station, the pads are cleaned, and the port is replaced with a new one — not reseated, since reseating a port whose joints have already failed once rarely holds for long. Finally the console is reassembled and run under a sustained 4K load with a long cable through a stretched cable path, to catch anything intermittent before it goes back to the owner.
If you are curious about how similar signal and bandwidth problems show up on PCs rather than consoles, our guide on a gaming PC dropping Wi-Fi mid-match in Bathgate walks through the same discipline from the network side, and optimising Windows 11 for gaming covers what is worth tuning once the hardware is behaving itself.
When It Is Worth Repairing, and When It Is Not
A standard HDMI port replacement on a PS5 is usually worth doing. The console is not old, the rest of the board is almost certainly fine, and a replacement port with a careful reflow typically outlasts the warranty on a new console. Where we have the honest conversation is when the retimer chip or several nearby components have gone with the port; that is a longer job on a more delicate part of the board, and depending on parts availability it can approach the point where a trade-in makes more sense. We flag that at the diagnosis stage so you can decide before any work starts, not halfway through.
Getting a Console Looked At in Edinburgh City Centre
Our workshop is at Parkhead Drive on the west side of Edinburgh, a straight run from the city centre along the Western Approach or the number 2 and 25 bus corridor. Most city centre customers drop a console in on the way home and collect it the next day, and we offer collection and return across the New Town, Old Town, Tollcross, Fountainbridge and down to Leith if a trip across town is awkward with a boxed console on a bus.
For the whole list of console work we handle locally, including Xbox and Switch alongside PlayStation, our Edinburgh City Centre console repair page has the device types and the usual turnaround times.
