Are there negative stars?

Bought the TV was in another mail-order in July 2014. Picture and sound are OK (if it works sometimes) but that's it.

The device has to date never worked satisfactorily. Software errors wherever you look. Unfortunately, I've been waiting too long to return - your own fault. But I had hoped that this can be eventually resolved times.
Earnings after numerous updates, communications with the Philips service center and new installations is now that it no longer works and must be returned for repair. Actually, I wanted to give the TV back to the dealer, but did not want to have him.

Who is a masochist, the device may feel like buying. For all other however AWAY !!!
The software is currently a disaster and can not be solved well.
