Problems with TNT boxes
Over the last few years , there have been a number of small but annoying little problems, easily sorted out, but when it happens, it looks like disaster.
This particular problem has come up several times: TNT box ( mainly the older standard definition types ) loses all channels and will not retune. Keeps going round the loop, apparently tuning but getting no results. There is no indication of signal, so these faults are sometimes reported as “no signal” or “dish faulty”. A quick check with a meter showed the signal was fine.
All that is required is to do a factory reset:
Remove the card
Go to main menu
Choose factory ( Usine) reset ALL
Afterwards, the box will perform its initialisation and look for software update. Ensure it completes this without any interruption, I cannot emphasise this enough, there is a risk of complete memory corruption if the update process is not completed. A box in that condition is useless, you can send it back to France for repair, but so far the procedure and the download is not available online and the cost to send away is high.
Once complete the box will tune in again and work as normal.
