Instrument cluster display

[spannerrash]

Hello all
The center lcd display on my instrument cluster has started playing up in this cold weather. It is not working at all first thing in the cold morning. Or is at least so dim I can't see anything. Then as the car worms up, it starts to get better.

I suspect the lcd screen needs to be replaced. Is this a common fault and where can I get hold of a screen?

Is there anything else you think I should be looking at if not the screen?

Thanks all
