Perhaps this should be a New Thread? My issue was not with the IFE but with my Business Class seat that was inoperable from LHR-MEL (QF10 21/22 July).
Like 'The Mountain', I found the inflight crew to be excellent in trying to assist. None of the seat controls worked after takeoff from LHR, but one (only one?) crew member (Thank you, Andrew) knew how to make a manual adjustment and managed to get a few degrees of recline, which was enough for my wife to use her laptop more or less comfortably on the leg to DXB. During Dubai refuelling stop, 2 engineers worked on the seat but when we re-boarded, the seat had an "INOP" sticker on it and none of the seat controls (or even the privacy screen) would work. The QF Ground Supervisor and the cabin crew were sympathetic and helpful but the plane was 100% full (and no crew travellers) so there was little they could do except offer to deplane us and our luggage with the possibility of bumping someone off the QF 2 departing DXB 4 hours (?) later. My wife had meetings in Brisbane the next day so that simply wouldn't work (apart form the embarrassment of bumping other pax). We also had paid for an overnight hotel booking at Melbourne airport. [We knew the flights were all fully-booked because when we booked on 2 May, QF2 (the Sydney flight) was already sold out; hence the LHR-MEL-BNE routing].
After take-off from DXB, CSM offered to make me up a 'bed' on the business lounge bench; that at least allowed me to have a (more or less) flat "bed" but it's pretty narrow and has seat belt buckles along its length, but for the non-sleeping part of the journey, I sat bolt upright in an INOP seat.
The point is, my wife and I paid full price for 2 J seats and we only got one functional seat. Our visit to London trip was a relatively short one for a special occasion, and I had recently had a pacemaker inserted: for each of these reasons we thought it was worth paying for J. We are also both Platinum.
Both the Ground Supervisor and the CSM assured us that a special section of QF Customer Care in Sydney would contact us upon our return about compensation: eight days later we have heard nothing. The CSM did offer 5,000 FF points, and they are now on my activity statement, but I will be very disappointed if QF thinks that's all their J seats are worth.
Can anyone suggest what an appropriate compensation would be?
