pannasonic DMR-Eh50 nolonger accepts scart interface?

I was recording on my hard drive yesterday through scart. however today i can only get a picture through RGB. The unit will nolonger accept any inputs through the external scart leads or rgb.

The hard drive recorder now only works as a dvd player and then only through rgb not scart or Component connections to my tv. I know it is not the cables or tv as i have tried another dvd player in it place and that was fine
