Onkyo AV RECEIVER TX-NR515 (Ashton-U-Lyne OL6)

Hi this is working via the optical lead but not via HDMI as that's the way I bought it . Good for cinema surround. Doesn't come with a remote but most functions can be accessed via buttons on front.
Needs a wipe but was in use until 2 days go. Needs an active sub or connection to an amp for sub.
Please see photos for rear connections and condition.
