Again, sorry to bump this, but for those who are interested my AE500 just turned up at work!!
Shocked and stunned, I phone Panny yesterday and they said Monday but here it is! 10/10 for them as they have only had it a week.
On the receipt it says replaced BQ Power Somethingorother and Lamp (woohoo) and no charge.
I will plug it in tonight and let you know how we get on!
