rear screens dead as a doornail

[goldie01]

Evening all new member looking a little advise from those in the know. Have Just purchased a 2005 xc90 d5 se for a family bus such an upgrade from using my l200 all the time feel like a millionaire sitting in this thing and dont even have to move to change gear

Anyhow i cant get the rear headrest screens to do anything no blue screen nothing at all. Its the system with the multi dvd changer in the boot i also dont have the remote. checked all the fuses which are fine,changer will load and eject the cartridge without issue. tried pushing the power button on the screen with key in position 2 (ign on) and with engine running but still nothing.

Any of you people that are familiar with these things any ideas no handbooks came with the car so im hoping its just a case of me being stupid and doing something wrong.

If push comes to shove and the screens are scrap ill replace with aftermarket and run a couple of ps minis or something off them.

Thanks in advance guys
