If your LED mirror will not work, first check whether it has lost power or whether just one function has stopped responding. A completely dark mirror points to a different problem from working lights with an inactive demister. These simple checks help you describe the fault clearly and avoid replacing a mirror that only needs a control adjustment.
Start with the controls and power supply
- Make sure the wall switch or normal isolating switch supplying the mirror is on.
- With dry hands, try the mirror's light control. Use the tap or hold action shown in its instructions; holding a dimmer may change brightness rather than switch the light on.
- Check whether the brightness has been left at its lowest setting. Some mirrors remember the last setting.
- If it is a rechargeable makeup mirror, recharge it with its specified charger or cable. A mains bathroom mirror does not need charging.
Do not remove the mirror's electrical cover. If there is a burning smell, damaged wiring, water inside the unit or repeated circuit tripping, stop using it and arrange an electrical inspection.
What does the symptom tell you?
- Nothing works: check the normal supply switch first. A supply, driver or connection fault then needs professional diagnosis.
- The light works but the demister does not: use its separate control if fitted and allow time for the heated area to clear. The whole mirror is not necessarily heated.
- The light is dim but steady: check the dimming setting, clean the glass and compare how it looks with the room lights on.
- Only part of the lighting works, or it flickers: note which section is affected and whether it happens in every colour setting. This helps identify a component fault.
- The light will not switch off: follow the focused LED mirror switch-off troubleshooting guide.
Get useful help without repeating the checks
For an LED Mirror World order, email help@ledmirrorworld.co.uk with your order number, a photo of the mirror and a short description or video of the fault. Include whether the wall switch is on and which functions still work. Our mirrors have a three-year warranty covering manufacturing faults, so contact us before arranging internal repairs.
If you are ready for an upgrade
Choose around the improvement you want. Backlit mirrors create a welcoming wall glow; front lighting brings illumination towards your face; dual lighting combines both directions. A new mirror is a chance to improve the routine, but have any supply fault resolved first.
80 × 60 cm gold frontlit rectangular mirror — £159. Choose this when light towards your reflection and a decorative frame are priorities. Dimming, three colour modes and anti-fog make the warm outline practical for everyday use.
60 × 80 cm double-light rectangular mirror — £129. Practical front illumination and a softer rear glow give you both effects in one design. Its adjustable brightness suits a change of mood as well as a busy morning.
60 × 80 cm backlit mirror — £139. Choose it for a soft halo and a clean rectangular silhouette. Three light colours, memory and anti-fog add convenience; keep good supporting lighting if detailed grooming is your main task.

Repair or replace? A useful decision
If the glass and frame are in good condition and a compatible part is available, repair may be the better route. Replacing the whole mirror becomes more attractive when parts are unavailable or you want a different size or lighting arrangement. Ask support to assess the symptom before buying a driver or LED strip.
For a new installation, share the fault with the installer as well as the seller. Note whether it has ever worked correctly and whether the issue appeared after a wall-switch change. That helps separate an installation question from a product fault.
