It seems there's lots of problem with the A346. Yours just went "tech", mine had to be replaced altogether! Recent BKK-LHR (Feb 20th) - we were taxiing on the tarmac almost ready for take off, suddenly the captain announced that there were problems with the IFE for the whole flight (and some other electrical problems - and I also noticed that 2 toilets won't "suck" properly) we had to change aircraft. Waited on the tarmac for 3 hours before we got on the new plane, eventually taking off 4 hours late. All the while the captain made announcements twice - in very broken English!
