Vintage 1994 JVC 5-Disc CD Changer Model XLF-215. No remote control.
It does not enter or exit standby-mode when using the power button. It does turn on from standby mode when opening tray and also by pressing PLAY / PAUSE which is normal. In our tests, the display only shows standby mode when first plugging-in. According to the manual, disconnect power cord from wall outlet to turn off completely.
It does not spin the tray when using DISK SKIP when tray is open. This might be cleared-up with some cap changes on the logic board. Other than that, it does play CD's and advances normally.
