You will need a remote control to use this- either a replacement remote, original remote, or a universal remote control. I used a Harmony Logitech remote to test them. Your local $1.25 store should sell compatible universal remote.
Had two Sharp Aquos BD-HP20 decks, both in the same good condition. One has been sold so just one left. Fully tested with BD movie, DVD, and audio CD. These retailed for $499 when new- not a cheap plastic player like what they are making nowadays.
