Monitor problem – what you can check before calling support ….

The first thing is to check if the fault is with the monitor – or your PC.

This is important because – if it’s the cable or the monitor, it can be easily replaced yourself without too much expense (possibly just £10 or £15 – or even £0 which is perfect!).

Here’s how to see if the monitor or the video cable is the problem:-

1. Monitor is receiving power – either a green/blue or amber light. *
2. Cable is securely attached to the screen – tighten the thumbscrews if necessary.
3. Cable is securely attached to the back of the PC – tighten them if necessary.

4. Ask a friend / colleague if they have a similar cable (blue is VGA, white is DVI and black is HDMI).

5. Ask a friend / colleague if they will let you borrow their monitor – to see if it is at fault.

If you still see nothing on screen, the fault is likely with your computer itself. It contains a video card (either built-in) or slotted in which may be faulty and need replacement. Or there could be a more serious problem with the circuitry inside your PC which may make it not economical to repair.

* an amber light can mean one of two things – it’s in “power save mode” or not connected to the PC. In power saving mode, usually pressing the space bar on your keyboard (and/or moving the mouse) will restore the screen to life.

* If not connected to the PC, usually it will show the words “No connection” but again these words may not be visible if the monitor’s gone into “power save” mode so you may wish to do the above first to check.
