Bought Formuler 4k S, it work 2 weeks without any problems.
Now reciever losts signal in 1-2 minutes after power on. It's very overhead near sat cabel in.
I reset setting and changed firmware. Nothing helped. Is it hardware problem?
I can not find official service center in Moscow, Russia.
Did you check your sat cable first? Maybe short circuit at the end of the cable. Try to refresh your end of cable and check nothing do short circuit.
Yes. I tried with other sat antena and cabel in other house.
Ok, could be problem with the Tuner if you always lost the signal. Heat can be normal, it depends always how much heat. Go to your dealer and change the Box, you have Guarantee.
