I have a problem that so far has defied logic. I have a had a MDS-JE940 connected to a switched power plug on a Pioneer VSX5300 receiver. I have a used a remote control with a time event macro to record a radio show without incident for years. The remote powers on the Pioneer VSX5300 receiver which provides AC power to the MDS-JE940. When this happens the MDS-JE940 has started to eject the disc. This has never happened before and causes the deck not to record because the disc is ejected.
I also have a MDS-JE440 connected to a Yamaha RX-V3900 receiver that does not eject when the receiver powers up. I switched the minidisc decks and now the MDS-JE940 when connected to the Yamaha RX-V3900 does not eject on power up. Now the MDS-JE440 ejects when the Pioneer VSX5300 receiver powers up. I decided that the Pioneer VSX5300 receiver must be causing some type of power spike when powering up causing the minidisc decks to eject so I replaced the Pioneer VSX5300 with another Yamaha receiver a RX-V4600. Now the MDS-JE440 still ejects when the Yamaha RX-V4600 powers up. A different minidisc deck connected to a different receiver still ejects on power up? The only thing the same is the speakers. Any suggestions?
