It may or may not need reprogramming. Itron also do a similar drop-in replacement.

There are 4 issues:

- Power supply. There is no 5v on the receiver. There is a 3.3v rail, which is probably not man enough to drive a big display; you will need to make your own 5v from the 12v rail (the main board gets 12v from the psu board).

- Signals. As the display board is likely to be 5v only, you need to wire it permanently in write mode so that it won't ever try and drive 5v down the 3.3v buffers...

- Wiring. The VF won't have the right plug. You will need to sort this out - it may be easier to pull the signals off the main board connector.

- Code to drive it. This is not going to be hard, but it does need doing, it's unlikely it will be an exact drop in replacement. The code that refreshes the display is in the kernel though, so you can change it - but without reflashing the unit, you won't be able to mess with the initial "booting" screens.

I've got one of the itron screens here and have been meaning to get round to trying it for the last year at least....!
