Alba dvd70 remote control

Question

Hey, I have an ALBA DVVD70 dvd player and lately the remote control has gone haywire. The functions dont work on it, almost every button comes up as a number on screen when it is pressed, bar a few that turn the volume down or freeze the picture. Any functions that it does do(as listed) are on completely the wrong keys and dont happen on the right keys. Any ideas??
