I meant on the Luxman unit itself, but with remotes that old I suppose it could be either. A Harmony might do it if the problem is in the remote. You sure you're aiming it well at the receiver's sensor? I prefer having a remote myself. Ten four....cleaned sensor window....tried many different angles & distances....it worked the first night ...then quit Process of elimination....I kept my 1997 Teac ACG8520 / Costco unit....remote works awesome....but I must say...everything else about Lux works & sounds great!.....
