Central locking not working

hi there,

the other day my mothers seat Ibiza would lock the car when you put the key in the door but wouldn't unlock it. I decided to replace the door lock mechanism which when I tested it with everything apart activated the central locking which I was happy with. i then put everything back together and then realised that it no longer worked (including the buttons on the driver door to unlock and lock the car which worked previously). the radio screen is also flashing on and off and the display doesn't seem to be working 100% with some of the characters displaying but others not

does anyone have any idea what this could be I've checked the fuses under the steering wheel and they all seem to be intact.
thanks in advance
cheers Andy
