Unfortunately, only for a few days, a TV that works

Have purchased for the kitchen this TV. The features speak for themselves, in particular the integrated satellite receiver was the selection criterion!
Installation was a bit tricky:
- When tuning the new stations are eg DasErste not found right away, by manually adding the correct transponder it worked after all
- The Order of the stations in the desired order was very time consuming.

Features:
- First everything worked,
- But, the switching time between the programs was eternal, even if you switch between the functions and the TV turns on, it takes forever until he "raised" is.

The main shortcoming is that he no longer went to a couple of days:
- TV 1 has made limp after 2 days. The stand-by light did not go on. But I have found no explanation. Then I sent him back.
- Unit No.2 was was already after only two days on the doorstep. This has then held for about 3 weeks to the same problem arises.

Very unfortunate, will now try out a different model and hope I have more success.
