Default Panasonic DMR-ES20 DVD Recorder Issue

All of them done without component diagnosis?


I have an DMR-E30 with an issue very equal. You can switch it on and
nothing happens. It looks dead. But wenn you switch it of (10s
keypress) it write "BYE" in the Display. All Powerrails are fine.

I have a servicemanual and I know there is a maintanance mode. But it
did not work. So I realy believe there is something wrong in the
mainprocessor, because it can write "BYE" in the VFD, but it did not
change its behavier with maintanance jumper. Strange!

Sounds like a processor code crash. Noisy power rails. Bad supply
decoupling.


The old Panis are famous for a fault in the supply, especially of the
chip someone wrote before in this thread. Unfortunatly some have
bigger problems.

That is very sad, because the human interface device was much more
sophisticated than on my new 2000Euro TV with integrated recording
cabability. But fortunatly the TV program is so bad in these days that
recording is not necessary anymore.
