i'am dealing since today morning with a strange behaviour of my TV, sometimes it shuts down, the red light blinks for a few seconds and then it turns on again automatically. Now it's doing this all 10 or 15 minutes

i already made a firmware upgrade and the procedure mentioned on the user manual for a similar issue (Switch the TV off and on again with the switch at the bottom of
the TV. Check if there is enough space for ventilation. Wait until the
TV has cooled down.)

but the problem seems to remain.

a help would be great...

best regards
