Ich have an DMR-E30 with a problem very equal to your problem.
It goes on, does absolutly nothing, if I press the off-button for
10second it show "BYE" in the VFD and switch off.

I know that the powersupply is working.

How? If you're going on that it's outputting voltage, that only proves the power supply is not dead, but that's not enough. I've seen these sag and recover so quickly that you won't see it on a DMM. I repaired several of these Panasonic recorders with a cranky smps or buck converters that refused to complete the boot.
