FYI the new firmware update (1.00.73) that appears to being pushed out to FVP boxes seems to attempt to deal with the turn on issue that a number of us have been suffering. For covenience, here's my detailed post on the "Failure to turn" on thread:

My 4000T 1Tb received a new firmware update sometime yesterday. The firmware is now Software version UKTFAE 1.00.73, Loader version 1.03 Dated 11 Jan 2106.
On limited testing since then, the new version appears to have resolved the turn-on issue at least for my TV, a Sony KDL 32EX503. And I no longer need my work-around described in post #33 of a RCA/Scart cable connected as well as the HDMI cable.
On my set up I have (a) HDMI-CEC (ie Sony Sync or Panasonic Viera Link) switched to ON on the TV (b) the power save option on the FVP switched to OFF.
Now in all 3 FVP off states, the FVP will turn on and turn on the TV (the 3 states being (i) FVP off (ii) FVP off but recording (iii) FVP off but in the 10-15mins before a recording is due to start when the FVP is in some "pre-recording mode" waiting for the program start signal from the broadcaster).
I have not noticed any other changes to the operation of the FVP - in particular the Genre search on the Schedule appears still to be limited to the next 6 or so hours.
