CELCUS 22913DVD 22" TV With built in DVD player see details (Harborne B32)

Hi all, this is a very nice 22 inch tv that has been passed to me by a neighbour who wanted me to recycle it so here it is. Unfortunately the remote control has been lost but I have tried it and it does seem to work ok with the built in dvd player loading up a disk but because I had no idea how to use it that was as far as I could get. There is a small control on the side of the tv which seems to work ok turning it on and changing the sources etc. I ran a set top box though it and the picture looked ok. Scart and HDMI connection are on the back. Kind regards Eric
