yesterday we wanted to watch tv, switched it on as usual, and it was gone in 25 secs. tried again - gone.
I tried to read many forums and watched many videos, the issue appears pretty the same as described here viewtopic.php?t=9517
Within the 25 secs everything is working fine, network is accessible. sound and picture is ok, menu is accessible - all good. Even Service Menu is accessible, but it also goes off in 25 secs.
Is there any way to get it fixed?
