# Screen Flickering

The V240M screen jumps or flickers, usually when the device is handling peak usage — a cold restart resolves it.

## Symptoms

You may see:

* The terminal screen jumps or flickers during use.

**Most likely cause:** the device is handling peak usage. A cold restart usually clears it.

## Resolution

{% stepper %}
{% step %}

### Switch the terminal off

Hold down the red `X` button for 10 seconds until the terminal powers down.
{% endstep %}

{% step %}

### Remove all power sources

Make sure the terminal is not charging and is disconnected from any power supply.
{% endstep %}

{% step %}

### Leave the terminal off

Wait 5 minutes to allow the device to perform a cold restart.
{% endstep %}

{% step %}

### Switch the terminal back on

Hold down the green `O` button until the terminal powers back on.
{% endstep %}

{% step %}

### Perform a test transaction

Log in and process a £0.01 test transaction to confirm the screen is stable.

✅ **Screen is stable — stop here.** ❌ **Still flickering — see below.**
{% endstep %}
{% endstepper %}

## Still not working?

If the screen is still flickering after a cold restart, a [configuration update](https://helpcenter.verifone.com/webcom-tms/terminals/configuration-update) may be needed.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.verifone.com/support-uk/v240m/errors/screen-flickering.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
