I've been using my XL201 for many months now virtually problem free, but late last week, the guide reported problems downloading, and we began to miss vital programmes.
Since then, whilst browsing the guide, i get a EHSHELL.EXE error and MCE bombs out. I tried applying all the fixes in here: http://club.vaio.sony.co.uk/clubvaio/GB/en/forum/viewthread?thread=36767 and get nowhere, indeed now i'm also having trouble with the screen display appearing after sleep.
I find that by re-sleeping and waking up again, the display does appear.
Any ideas/solutions warmly appreciated. 
Thanks, Chalky
