PS5 white light on but no signal on TV — what's actually wrong

You press the PS5 power button. The white light comes on. The fan spins. But the TV shows "No signal" or stays black. Panic-inducing, but the fault is nearly always one of four things — and the first three cost nothing to check.

The one-minute checks

Before assuming anything is broken:

• Try a different HDMI cable. Cables die surprisingly often, especially the ones that came in the PS5 box and get flexed every time you move it.
• Try a different HDMI port on the TV. TV HDMI ports fail too. Cycle through all of them.
• Turn the TV off and on fully (power at the wall, not the remote). TVs get confused about HDCP handshakes; a full power cycle clears it.
• Hold the PS5 power button for 10 seconds to force a full shutdown, then boot normally. Stuck display states often clear here.
• Try a different TV entirely if you can — the neighbour's, a friend's. If picture appears on another TV, the fault is with your original TV.

Most "no signal" calls end here. If none of these help, continue.

Check the HDMI port itself

Shine a bright torch directly into the HDMI port on the back of the PS5. You're looking at a rectangular opening with a metal tongue in the middle. Compare what you see to a photo online.

Signs of port damage:

• The tongue is bent up, down or sideways
• The tongue is pushed back into the port body
• One or more of the 19 gold pins is visibly flattened or missing
• The outer metal shroud is bent or crushed
• The port visibly wobbles when you plug the cable in
• Picture flickers in and out when you wiggle the cable

Any of those, and the port needs professional replacement. See our PS5 HDMI port repair service page — typically £80-130 fitted.

If the port looks pristine but the cable test and TV test both failed, move on to safe mode.

Safe mode — rules out software corruption

Safe mode uses a minimal display mode (1080p, 60Hz) that bypasses the main OS. If safe mode gets a picture when normal boot doesn't, your system software is corrupted, not broken hardware.

To enter safe mode:

1. Hold the PS5 power button until you hear the second beep (about 7 seconds), then release. 2. Connect a DualSense controller by USB cable (wireless won't work in safe mode). 3. Press the PS button on the controller.

If safe mode works, try:

• Option 3: Update System Software — re-downloads and installs the OS.
• Option 5: Rebuild Database — non-destructive, can fix display-layer corruption.
• Option 6: Reset PS5 (Keep Data) — nuclear option, but keeps saves if cloud-synced.

If safe mode also shows no signal, the fault is hardware — almost certainly the HDMI port.

The HDMI IC — a less common but real failure

The HDMI port is the socket. The HDMI IC is the chip behind it that drives the video signal. If the socket looks fine and safe mode doesn't work, the IC itself may have failed — often caused by a surge (storm, badly-wired TV, failed soundbar). Symptoms: port looks perfect, no signal on any cable or TV, safe mode no good.

HDMI IC replacement is a much more involved repair than port replacement — it's a BGA (ball grid array) chip that requires proper rework equipment. We do it, but the quote is higher (£150-200) and the work takes longer.

When to send it in

If the cable and TV checks are clean, the HDMI port looks damaged, safe mode doesn't help, or wiggling the cable makes picture flicker, the console needs professional repair. Post it to us — free diagnosis, no-fix-no-fee, 90-day warranty. Most PS5 HDMI repairs return within 3-7 working days. See the full PS5 HDMI port repair service page for pricing and what's involved.
