The most common monitor faults
| What you see | Usual cause |
|---|---|
| The monitor won't turn on, not even the indicator light | A faulty power supply (most often leaking capacitors). |
| The picture is only visible when you shine a torch on it | The backlight isn't working – the LED strips or their power supply. |
| The monitor goes dark after a few seconds or flickers | The power supply or the backlight driver. |
| Vertical or horizontal stripes, a broken-up picture | The control board, the connecting cable or the panel itself. |
| “No signal” even though the cable is fine | A faulty HDMI / DisplayPort input or the control board. |
| The buttons or menu don't work | The control button board or firmware. |

When a repair is worth it
The power supply, backlight and inputs are the most common faults, and repairing them is usually much cheaper than a new monitor – doubly so for larger, gaming and graphics models. On the other hand, a cracked or mechanically damaged panel is usually not worth replacing: a new panel costs about as much as a whole monitor. We'll tell you that frankly after diagnostics too.
What to prepare
- Bring the monitor together with its power adapter if it has an external one.
- Tell us exactly what's happening and when it started – it makes diagnostics easier.
- If you're sending the monitor, pack it in its original box or otherwise securely so that no pressure is put on the panel.

A laptop display is a different repair from a standalone monitor – see laptop repair.
