I have two KDL32S5500 units which worked fine until the Freeview switchover.  Now they both lock/freeze sporadically when choosing the Electronic Programme Guide (which is alot slower when it does actually work).  When the lock happens they turn themselves off (not just to standby), then come back on again after 30 secs or so!  For info, automatic updates are turned on.

To note: I have tried turning off updates after reading a few forums (as the epg may trigger a software check), but theyre both still playing up.  I have also tried not opening the EPG until a few minutes after the display has been turned on - but to no avail.

Please Sony can you issue a firmware update?  it seems to be a similar issues to other models (eg  KDL32S5100) which is fixed with a firmware revision.
