Hello everyone,
I have a mci500H, with the latest firmware (v1.17).

My problems are:
1) The volume increase (or decrease) by itself when I try to increase (or decrease) the volume with the remote controller or the buttons with front panel.
2) The 2d problem (which come with the first): when I turn off the mci500, the system turn off in the "eco - stand by"

I never experienced those both problem.

The problem occurred since I connected my mci500H with RJ45 cable to my internet box.
When my system was connected by wifi, there was no problem.

The procedures that I have tried to fix the problem without success:
- restore the firmware
- restore the manufacturer parameters
- unplug the electric source during 1H

After these procedures, when I connect my mci500H with RJ45 cable, the problem come back !

I have to try the connection by wifi, in order to see if it comes from the nature of the connection (wifi or RJ45) or if it comes from other stuff.
Every suggestions are welcomed
Thanks !
