Panasonic DMR-EA48VK DVD Recorder

I had purchased a Panasonic DMR-EZ48K Recorder and immediately experienced hardware issues. The first unit would lockup and not respond to commands, to include pressing the reset button, channel reset, and/or power button.
After 1 1/2 months, Panasonic technical support instructed me to return to the store where purchased for a replacement. The second replacement unit had other malfunction issues, to include not reponding to a programmed channel, even though it was in the manual channel list. Mostly lower channels. Couldn't operate copy functions or open DVD disc drawer when this occurred. Panasonic technical support advised to return this unit to the store for a third replacement.
The third replacement malfunctioned immediately by becoming stuck in the "HELLO" display. No other options could be used, even after resetting reset button, power button, and channel reset. Panasonic technical support stated unit was defective and to return unit to store. That's it! No more. Three strikes and your out Panasonic.
