Plasma 'creaking' as it warms up.

I have a series 5 Toshiba and have noticed that when its warming up, it 'creaks'.. Its makes a a series of cracking and popping noises.. Not very loud, I think its just caused by part expanding as they warm up.

Its not an electronic noise and is definitely coming from the plastic surround, as if I press it with my finger it makes the same noise.

It nothing serious, I just wondered if I was the only one who had noticed this and wondered if anyone had found a solution.. I wondered if tightening the screws (or even slackening them) might help.
