Wall mounted 21" TV with DVD player (Malvern Link WR14)

Techwood TV with DVD player integrated. 54cm/21" screen. Working order when last checked but that was a few years ago so no promises there. Has remote control. To the reverse there are sockets marked ANT, SCART, VGA, SPDIF, HDMI, USB, common interface, 3 unlabelled probably AV sockets, and what looks like a headphone jack socket. I only have the wall mounts fixings as pictured for this, the arm opens out so you can angle it in different positions. I have the large heavy duty screw style fixings that go into the wall (next to remote in picture, they're 7.5cm long!) but not what they would screw into the wall with but I expect you could get some of those from a hardware/DIY shop.
