TV forgets its LAN-Connection peridodically

[wolfk]

Hello,

I recently bought a new TV 37 PFL 6007k, which is connected by LAN (wired) to my router.
Its a quite nice TV and all internet connections and the connection to my TWONKY media server
(Mybook, 3TB Harddisk) usually work well.

It is however very annoying that the TV periodically "forgets" that has a wired LAN connection.
This has the effect, that eg. the connection to the TWONKY-server cannot be established.
The menu then displays a screen (in German):

"Schalten Sie Ihren Computer ein uns starten Sie Ihre Medienserver-Anwendung.
Der Fernseher sucht kontinuerlich nach einem Medienserver-Programm"

with only one option "Stoppen" (=stop) for infinit time (some 10 minutes).
(If this is done, of course no connection is established. )
My mediaserver is still running, however.

The only possibility to get it running again, is to completely set up the internet connection again.
I assume, this is a firmware error.
Could you please fix it, and inform me when it is fixed?

kind regards

I have to add to my post from yesterday, that I had installed the newest firmware version (auto-loaded on configuration)
QF1EU-0.150.82.0 (generation date 17/12/2012)

Yesterday night I downloaded the newest version from the Philips website (0.150.83.0, date published 4.2.2013),
but the problem still remains. In the middle of a photo show from the TWONKY-server, it stops and
displays the screen, which I have described in the last posting.
