The unit was purchased as a gift for an elderly person (it was aware of a device with on-site service selected with very good reviews - unfortunately the manufacturer's service quality was not involved in the decision). It was set up (though it takes time, but there are basically no major problems - after about 7 - 8 hours all use already) - unfortunately it was after 48 hours already again completely broken - could not even Wedren booted and then comes the odyssey which is not even after more than a month still far too late. The Samsung Onsite Service deserves its name not - it exists purely and not left - the staff are indeed very well trained and always friendly and polite on the phone, but that's all that is available to decision-making competence. It is a service ticket opened and then you have to wait for days until you are called by the appropriate service company. The service company itself is outsourced and locally no one comes from the technical service - the unit is only picked up by a shipping company and that can take, because it was reported that only one person is - that is, you need to pick up appointment a 2nd, physically healthy person who helps when removing packaging, and transport. In addition, you must provide a full and detailed description of the fault by e-mail as a customer - ..... ?????? (I'm not a Fersehtechniker why I need to know wass is defective, for me it is important that the purchased part functions as described) .... but that is of importance because probably only being tested and replaced, what the customer indicates defective - more functional tests no longer see well instead - just as the rest of the procedure can be explained - the unit came after another week allegedly repaired back - now a month has passed - was again fully furnished in about 8 hours and was then suddenly the CI + module no longer decipher. So, several CI + modules to test concerned, the unit several times completely reset, re-set (one day work again) always the same result - was several times on the phone with the customer service and eventually (already unnerved) remote maintenance with the Samsung technicians (network yes every set) agreed. TV has been switched off and shortly before remote maintenance again - the unit had now again lost all channels and settings, and is well again defective - the switched technicians had neither the time, nor the inclination to start a diagnostic and really trying remote maintenance - he exhibited simply pick a new ticket from. Requests to Samsung view to securing exchange of new, unusable equipment to a functioning new device, are completely blocked and are fruitless, now to be repaired again - service company does not even call after 2 days - completion of repair is well again in the week field lie. Meanwhile, it does not matter if the device is ever work - far too much frustration associated with it - no one will have more fun with it. CONCLUSION: It was my first and because of the experience made so far and last Samsung device - a good company proves Always in an emergency - I've learned that the ratings of the manufacturer service purchasing decision a big laboratory autoclave are much more important than good equipment reviews - a Monday device may occur is important, as it will be dealt by the manufacturer.
